Stomach Bug Outbreak Continues to Grow Nearing 28,000 Cases Nationwide

This compares to just 1,180 cases reported during the same period last year, meaning this year's outbreak is running more than 13 times the historical pace.

The CDC's national case count has grown to 15,716 laboratory-confirmed cases since May 1, with an additional 11,841 cases under investigation — bringing the total to roughly 27,500 nationwide.

Officials cautioned that because of a roughly six-week reporting lag, the national total will likely keep rising even as case growth slows.

New infections now appear to be slowing. In Michigan—the hardest-hit state, with more than 13,900 cases—the state health department said new case reports and diarrhea-related ER visits are declining, and it has lifted its earlier advisory against bagged salad mixes, telling residents they can resume normal lettuce and salad-green habits.

There have been 740 hospitalizations nationally. Two people have died, both in Michigan among people with underlying health conditions.

Since May 1, the CDC has logged 13,895 lab-confirmed cases of the parasitic illness acquired in the U.S., plus at least 10,455 additional cases that are not yet confirmed or are still under investigation, bringing the combined total above 24,000 across 47 states. By comparison, just 1,180 cases were reported in the same period last year.

The largest known outbreak of cyclosporiasis in U.S. history is showing signs of slowing, even as the total case count continues to climb, health officials say.

The company said it has suspended all iceberg lettuce sourcing and production at its central Mexico facility and commissioned an independent review of its food-safety processes.

Taylor Farms said that, according to the FDA, there were no confirmed positive Cyclospora sample results from product testing as of Aug. 5, even as epidemiologic and traceback data continued to point to its iceberg lettuce.

The FDA is investigating six separate cyclosporiasis outbreaks in total. Officials caution that not all cases are linked to a single nationwide source — several smaller, distinct outbreaks may be occurring simultaneously.

Nationally, cases have now been reported in 47 states, with 517 hospitalizations and 2 deaths.

The CDC is expanding the largest known cyclosporiasis outbreak — linked to Taylor Farms lettuce — to 15 states, adding Arkansas, Iowa, Missouri, Nebraska, New Hampshire, and North Carolina, according to The Washington Post. Missouri alone has reported more than 1,000 cases.

As of August 5, the death toll remains at two — both reported in Michigan on August 3 — with no additional deaths confirmed nationally.

Additionally, Michigan's case count has grown to 11,508 as of the state's latest update, up from 11,234 on August 3. 193 people have been hospitalized since the outbreak began.

The CDC's laboratory-confirmed case count has grown to 10,468 since May 1, up from 6,707 just days earlier. An additional 12,255+ cases are under investigation, bringing the total estimated case count to more than 22,700 nationwide.

Officials said that both of the people who died had "significant underlying health conditions" that may have been impacted by the illness and ensuing dehydration.

Additionally, the first two deaths in this outbreak have been reported in Michigan.

Michigan's case count has grown to 11,234 as of August 3, with 193 hospitalizations, per MDHHS.

Federal health officials continue to investigate, believing there could be multiple cyclosporiasis outbreaks from different sources beyond the one linked to Taylor Farms iceberg lettuce, according to Harvard T.H. Chan School of Public Health.

Michigan's case count has grown to 10,386 as of July 30, with 193 hospitalizations, per MDHHS.

This is now considered the largest known outbreak of cyclosporiasis in US history, per The Hill.

Michigan remains the hardest hit with more than 10,077 cases, followed by Ohio with more than 2,600 reported cases. There have been 423 hospitalizations nationally and no deaths.

The CDC added Oregon, South Dakota, Vermont, and Delaware to its list of states reporting cases in its latest update.

Cases have now been reported in 45 states, with only Hawaii, Maine, Montana, New Mexico, and South Carolina reporting no cases connected to the domestic outbreak, per the CDC's July 28 update.

Michigan remains the hardest-hit state with 9,680 cases and 160 hospitalizations. Ohio, North Carolina, Illinois, Indiana, New York, Oklahoma, West Virginia, Arkansas, and Missouri have also reported cases in the hundreds or thousands.

The CDC's national surveillance count has grown to 6,707 laboratory-confirmed cases since May 1, with more than 11,500 additional illnesses still awaiting confirmation. States report a combined total of at least 17,812 cases — nearly 18,000 people, or four to five times the total case count seen in all of 2025.

Taylor Farms maintains there have been no confirmed positive test results for cyclospora in its products as of July 24. The company said it acted quickly, removing all potentially implicated product from the marketplace once questions were raised.

Michigan's case count has topped 9,200 as of July 27, up from 8,176 just days earlier, per state health officials.

Michigan alone has reported 8,176 cases as of July 23 — up from 6,571 — with 160 hospitalizations, per MDHHS.

The CDC's Taco Bell-specific outbreak has grown to 1,947 confirmed cases across 9 states as of July 24 — up from 1,644. Four states have been added to the outbreak: Illinois, Kansas, Oklahoma, and Pennsylvania. Illness onset dates range from June 22 through July 20.

Reuters reported an additional 72 people with the illness in a new cluster not previously linked to the current outbreak.

Per ABC News, reporting numbers have an average six-week delay between case reporting.

An update from the CDC has increased the number of confirmed cases to over 11,500, now spanning 41 states.

MDHHS recommends buying whole heads of lettuce rather than pre-washed bagged lettuce or pre-mixed salad kits. Before preparation, discard the outer two to three layers of leaves and wash remaining inner leaves thoroughly under clean running water.

HHS Secretary Robert F. Kennedy Jr. Said Tuesday the cyclosporiasis outbreak is "under control" and cast doubt on the link to Taylor Farms lettuce and Mexico, while the FDA's voluntary recall of Taylor Farms iceberg lettuce from central Mexico remains in effect.

North Carolina reported 307 cases as of July 17. Wake County has reported the highest number of cases in the state, with 295 as of July 20.

The CDC expects illnesses to continue increasing through the end of August, when the typical Cyclospora season ends. Cases have been identified in 34 states.

Michigan cases have risen to 6,571 as of July 21, up from 6,148 the previous day, per MDHHS. Cases remain highest in Monroe, Lenawee, Washtenaw, Wayne, Shiawassee, Jackson, Oakland and Livingston counties.

New York state has reported 576 cases since May 1 — up from 470 earlier this month, per NYSDOH Commissioner Dr. Jim McDonald. Approximately 70% of New York cases are from the New York City area. "New York isn't one of the five states linked to the Taco Bell-specific cluster, so we still don't know the source" for New York cases, McDonald said.

The FDA is continuing to test lettuce samples and produce at the southern border. So far, no positive test results have been found. The investigation remains ongoing and officials say multiple clusters may have separate sources.

Taylor Farms said the FDA apologized, noting "FDA has not identified a single positive product test result for Cyclospora." The company confirmed it is no longer sourcing iceberg lettuce from central Mexico for the remainder of the growing season and is continuing to work with public health officials.

The FDA announced Sunday that a previous laboratory test identifying Cyclospora in a Taylor Farms lettuce sample was a false positive. "The finding does not represent true amplification," the FDA said in a statement. However, the FDA clarified the false positive "does not change the basis for FDA's ongoing outbreak investigation or the overwhelming epidemiological data supporting the current voluntary recall by Taylor Farms," per NPR.

Consumers who purchased recalled iceberg lettuce should discard it immediately. Full refunds are available at the location of purchase. Contact Taylor Farms customer care at [855-455-0098](tel:855-455-0098) Monday through Friday, 8 a.m. to 5 p.m. PST.

The FDA has increased border screening for products implicated in the outbreak. Additional brands, restaurants, or distribution channels may be identified as the investigation continues.

Taylor Farms said it has stopped receiving product from the implicated lot, suspended distribution of iceberg lettuce from Central Mexico, and notified its customers. The company is continuing to work with the FDA, CDC, and state authorities.

The recall covers multiple iceberg lettuce and lettuce blend products sold under several brand codes including CV, MARK, MKTSD, TF, SY, PK, JB, and SUB. Retail products include Iceberg Salad (12 oz, 24 oz) and Shredded Lettuce (8 oz, 16 oz) with use-by dates ranging from July 18 to August 3, 2026.

Taylor Farms distributed the implicated shredded iceberg lettuce from June 29 through July 16 across 27 states - AL, AR, CT, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, MI, MO, MS, NC, NH, NJ, OH, OK, PA, SC, TN, TX, VA, and WI.

Do not eat shredded iceberg lettuce from Taylor Farms at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia.

Of those interviewed, 90% reported eating iceberg lettuce at Taco Bell before becoming ill.

The FDA and CDC have confirmed 1,644 cases linked specifically to Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia. 94 people have been hospitalized. No deaths have been reported in the Taco Bell-specific outbreak.

On July 17, Taylor Farms announced a voluntary recall of all iceberg lettuce sourced from central Mexico from the US market.

The FDA has officially confirmed that Taylor Farms is the single supplier of shredded iceberg lettuce linked to the 5-state Taco Bell outbreak, per its traceback investigation.

This is not the first time Taylor Farms has been connected to a food safety outbreak. The company was linked to a 2013 cyclosporiasis outbreak affecting 631 people in 25 states, and a 2024 E. coli outbreak tied to McDonald's Quarter Pounders that killed one person.

Michigan now has 4,312 confirmed cases and 102 hospitalizations as of Thursday — up from 3,762 earlier this week. Indiana has emerged as part of the multi-state outbreak, joining Michigan, Ohio, West Virginia, and Kentucky.

"We believe public health is a shared responsibility among restaurants, their suppliers, and authorities," Taco Bell said in a statement.

Taco Bell said it has voluntarily removed the suspected lettuce from its supply chain nationwide "indefinitely" and will replace it in selected states within the next day.

The FDA is investigating iceberg lettuce supplied to Taco Bell by Taylor Farms as a possible source of the outbreak, per NBC News. Taylor Farms did not immediately respond to a request for comment.

MDHHS is urging restaurants and commercial kitchens in southeast Michigan to take extra precautions with fresh produce — washing under clean running water and cooking whenever possible. "If you can cook it or peel it, it's much safer," health officials said.

The CDC is investigating clusters of cases linked across Michigan, Ohio, West Virginia, and Kentucky.

Michigan cases have grown to 3,762 as of July 15th, up significantly from 2,600+ earlier this week, per MDHHS.

Taco Bell has pulled ingredients including, but not limited to lettuce, pico de gallo, cilantro-based items and guacamole.

Taco Bell said in a statement that it has "voluntarily and temporarily removed limited ingredients at select restaurants as a precautionary measure," while noting that public health authorities have not officially confirmed a link to Taco Bell or any specific ingredient, supplier, restaurant, or retailer.

Taco Bell is being investigated by federal and state health officials for a potential role in the outbreak, per the Washington Post. Some patients told investigators they had eaten at Taco Bell — though others said they had not.

Michigan alone has reported 3,309 cases as of July 14 — over 65 times its annual average of 40-50 cases per year.

As of July 14, nearly 7,000 confirmed and probable cases of cyclosporiasis have been reported across 34 states, per the CDC and state health departments. No deaths have been reported at this time.

More than 1,000 patient interviews have been completed as part of the ongoing investigation.

Other food items cannot be completely ruled out as a source, health officials cautioned.

"Although we do not have a definite product identified as the source of the outbreak, we want to let Michiganders know what we have learned so far so they can take steps to protect their families," said Dr. Natasha Bagdasarian, chief medical executive for MDHHS.

The Michigan Department of Health and Human Services (MDHHS) announced Monday that early investigation results "point to lettuce or salad greens as a potential source for this outbreak." No specific produce, grower, or supplier has been identified.

Michigan cases have surged to over 2,600 — up from 1,562 just days ago. Michigan typically records only 40-50 cases of cyclosporiasis annually.

Local, state, and federal authorities including the CDC and FDA are investigating several clusters of cases across more than one state. Investigations to identify the source are ongoing.

Multiple states have reported an increase in cases over the last two weeks compared to the same period in 2025. The CDC anticipates case counts will continue to rise due to a 6-week reporting lag between illness onset and case reporting.

Cases have been reported in people aged 5 to 88-years-old, according to the CDC.

Michigan, which has the highest case count of any state, has reported 1,562 total cases as of July 10, per the Michigan Department of Health and Human Services. 44 Michigan cases have required hospitalization. The source of the outbreak has not been identified. MDHHS updates case counts daily Monday through Friday.

Officials urge washing all produce thoroughly under running water, buying whole heads of lettuce rather than pre-bagged mixes, and discarding outer leaves. Anyone with sudden, ongoing diarrhea should see a provider and ask specifically for cyclosporiasis testing, since standard stool panels can miss it.

Health officials have not identified a source. Contaminated fresh produce is the leading hypothesis; past cyclosporiasis outbreaks have been linked to basil, cilantro, raspberries, snow peas, and bagged salad greens. No recall has been issued.

Other states are also reporting rising counts, including Ohio (about 177), New York, and Illinois. The CDC's most recent national surveillance count is 145 cases across 17 states through June 16—a figure that predates and does not include the Michigan surge.

Michigan remains the epicenter, with cases concentrated in the southeast: Monroe, Lenawee, Washtenaw, Wayne, Shiawassee, Jackson, Oakland, and Livingston counties. The state normally sees about 50 cases in an entire year.

Michigan's case count is now at 1,251 as of July 9, per MDHHS. 44 of those cases were hospitalized.

In a press release, the Houston Health Department has reported 16 confirmed cases of cyclosporiasis in the City of Houston, in addition to 18 confirmed cases via the Harris County Public Health Department.

In Michigan, 36 people have been hospitalized. No deaths have been reported nationally.

A total of 21 states are included: Alabama, Alaska, Colorado, Connecticut, Florida, Georgia, Illinois, Kentucky, Louisiana, Massachusetts, Michigan, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia, West Virginia, and Wisconsin.

Health officials in Michigan have reported over 700 cases in a recent surge of people sickened across the state.

Cyclosporiasis causes intestinal illnesses, with symptoms that can persist between periods of brief recovery.

The cause has not been linked to a single source, and officials expect a peak seasonality of people sickened by the parasite in the summertime.

The CDC is tracking an outbreak of the parasite cyclosporiasis across multiple states.

Incident reported at United States.

This compares to just 1,180 cases reported during the same period last year, meaning this year's outbreak is running more than 13 times the historical pace.

Since May 1, the CDC has logged 13,895 lab-confirmed cases of the parasitic illness acquired in the U.S., plus at least 10,455 additional cases that are not yet confirmed or are still under investigation, bringing the combined total above 24,000 across 47 states. By comparison, just 1,180 cases were reported in the same period last year.

The largest known outbreak of cyclosporiasis in U.S. history is showing signs of slowing, even as the total case count continues to climb, health officials say.

The company said it has suspended all iceberg lettuce sourcing and production at its central Mexico facility and commissioned an independent review of its food-safety processes.

Taylor Farms said that, according to the FDA, there were no confirmed positive Cyclospora sample results from product testing as of Aug. 5, even as epidemiologic and traceback data continued to point to its iceberg lettuce.

The FDA is investigating six separate cyclosporiasis outbreaks in total. Officials caution that not all cases are linked to a single nationwide source — several smaller, distinct outbreaks may be occurring simultaneously.

Nationally, cases have now been reported in 47 states, with 517 hospitalizations and 2 deaths.

The CDC is expanding the largest known cyclosporiasis outbreak — linked to Taylor Farms lettuce — to 15 states, adding Arkansas, Iowa, Missouri, Nebraska, New Hampshire, and North Carolina, according to The Washington Post. Missouri alone has reported more than 1,000 cases.

As of August 5, the death toll remains at two — both reported in Michigan on August 3 — with no additional deaths confirmed nationally.

Additionally, Michigan's case count has grown to 11,508 as of the state's latest update, up from 11,234 on August 3. 193 people have been hospitalized since the outbreak began.

The CDC's laboratory-confirmed case count has grown to 10,468 since May 1, up from 6,707 just days earlier. An additional 12,255+ cases are under investigation, bringing the total estimated case count to more than 22,700 nationwide.

Officials said that both of the people who died had "significant underlying health conditions" that may have been impacted by the illness and ensuing dehydration.

Additionally, the first two deaths in this outbreak have been reported in Michigan.

Michigan's case count has grown to 11,234 as of August 3, with 193 hospitalizations, per MDHHS.

Federal health officials continue to investigate, believing there could be multiple cyclosporiasis outbreaks from different sources beyond the one linked to Taylor Farms iceberg lettuce, according to Harvard T.H. Chan School of Public Health.

Michigan's case count has grown to 10,386 as of July 30, with 193 hospitalizations, per MDHHS.

This is now considered the largest known outbreak of cyclosporiasis in US history, per The Hill.

Michigan remains the hardest hit with more than 10,077 cases, followed by Ohio with more than 2,600 reported cases. There have been 423 hospitalizations nationally and no deaths.

The CDC added Oregon, South Dakota, Vermont, and Delaware to its list of states reporting cases in its latest update.

Cases have now been reported in 45 states, with only Hawaii, Maine, Montana, New Mexico, and South Carolina reporting no cases connected to the domestic outbreak, per the CDC's July 28 update.

Michigan remains the hardest-hit state with 9,680 cases and 160 hospitalizations. Ohio, North Carolina, Illinois, Indiana, New York, Oklahoma, West Virginia, Arkansas, and Missouri have also reported cases in the hundreds or thousands.

The CDC's national surveillance count has grown to 6,707 laboratory-confirmed cases since May 1, with more than 11,500 additional illnesses still awaiting confirmation. States report a combined total of at least 17,812 cases — nearly 18,000 people, or four to five times the total case count seen in all of 2025.

Taylor Farms maintains there have been no confirmed positive test results for cyclospora in its products as of July 24. The company said it acted quickly, removing all potentially implicated product from the marketplace once questions were raised.

Michigan's case count has topped 9,200 as of July 27, up from 8,176 just days earlier, per state health officials.

Michigan alone has reported 8,176 cases as of July 23 — up from 6,571 — with 160 hospitalizations, per MDHHS.

The CDC's Taco Bell-specific outbreak has grown to 1,947 confirmed cases across 9 states as of July 24 — up from 1,644. Four states have been added to the outbreak: Illinois, Kansas, Oklahoma, and Pennsylvania. Illness onset dates range from June 22 through July 20.

Reuters reported an additional 72 people with the illness in a new cluster not previously linked to the current outbreak.

Per ABC News, reporting numbers have an average six-week delay between case reporting.

An update from the CDC has increased the number of confirmed cases to over 11,500, now spanning 41 states.

MDHHS recommends buying whole heads of lettuce rather than pre-washed bagged lettuce or pre-mixed salad kits. Before preparation, discard the outer two to three layers of leaves and wash remaining inner leaves thoroughly under clean running water.

HHS Secretary Robert F. Kennedy Jr. Said Tuesday the cyclosporiasis outbreak is "under control" and cast doubt on the link to Taylor Farms lettuce and Mexico, while the FDA's voluntary recall of Taylor Farms iceberg lettuce from central Mexico remains in effect.

North Carolina reported 307 cases as of July 17. Wake County has reported the highest number of cases in the state, with 295 as of July 20.

The CDC expects illnesses to continue increasing through the end of August, when the typical Cyclospora season ends. Cases have been identified in 34 states.

Michigan cases have risen to 6,571 as of July 21, up from 6,148 the previous day, per MDHHS. Cases remain highest in Monroe, Lenawee, Washtenaw, Wayne, Shiawassee, Jackson, Oakland and Livingston counties.

New York state has reported 576 cases since May 1 — up from 470 earlier this month, per NYSDOH Commissioner Dr. Jim McDonald. Approximately 70% of New York cases are from the New York City area. "New York isn't one of the five states linked to the Taco Bell-specific cluster, so we still don't know the source" for New York cases, McDonald said.

The FDA is continuing to test lettuce samples and produce at the southern border. So far, no positive test results have been found. The investigation remains ongoing and officials say multiple clusters may have separate sources.

Taylor Farms said the FDA apologized, noting "FDA has not identified a single positive product test result for Cyclospora." The company confirmed it is no longer sourcing iceberg lettuce from central Mexico for the remainder of the growing season and is continuing to work with public health officials.

The FDA announced Sunday that a previous laboratory test identifying Cyclospora in a Taylor Farms lettuce sample was a false positive. "The finding does not represent true amplification," the FDA said in a statement. However, the FDA clarified the false positive "does not change the basis for FDA's ongoing outbreak investigation or the overwhelming epidemiological data supporting the current voluntary recall by Taylor Farms," per NPR.

Consumers who purchased recalled iceberg lettuce should discard it immediately. Full refunds are available at the location of purchase. Contact Taylor Farms customer care at [855-455-0098](tel:855-455-0098) Monday through Friday, 8 a.m. to 5 p.m. PST.

The FDA has increased border screening for products implicated in the outbreak. Additional brands, restaurants, or distribution channels may be identified as the investigation continues.

Taylor Farms said it has stopped receiving product from the implicated lot, suspended distribution of iceberg lettuce from Central Mexico, and notified its customers. The company is continuing to work with the FDA, CDC, and state authorities.

The recall covers multiple iceberg lettuce and lettuce blend products sold under several brand codes including CV, MARK, MKTSD, TF, SY, PK, JB, and SUB. Retail products include Iceberg Salad (12 oz, 24 oz) and Shredded Lettuce (8 oz, 16 oz) with use-by dates ranging from July 18 to August 3, 2026.

Taylor Farms distributed the implicated shredded iceberg lettuce from June 29 through July 16 across 27 states - AL, AR, CT, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, MI, MO, MS, NC, NH, NJ, OH, OK, PA, SC, TN, TX, VA, and WI.

Do not eat shredded iceberg lettuce from Taylor Farms at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia.

Of those interviewed, 90% reported eating iceberg lettuce at Taco Bell before becoming ill.

The FDA and CDC have confirmed 1,644 cases linked specifically to Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia. 94 people have been hospitalized. No deaths have been reported in the Taco Bell-specific outbreak.

On July 17, Taylor Farms announced a voluntary recall of all iceberg lettuce sourced from central Mexico from the US market.

The FDA has officially confirmed that Taylor Farms is the single supplier of shredded iceberg lettuce linked to the 5-state Taco Bell outbreak, per its traceback investigation.

This is not the first time Taylor Farms has been connected to a food safety outbreak. The company was linked to a 2013 cyclosporiasis outbreak affecting 631 people in 25 states, and a 2024 E. coli outbreak tied to McDonald's Quarter Pounders that killed one person.

Michigan now has 4,312 confirmed cases and 102 hospitalizations as of Thursday — up from 3,762 earlier this week. Indiana has emerged as part of the multi-state outbreak, joining Michigan, Ohio, West Virginia, and Kentucky.

"We believe public health is a shared responsibility among restaurants, their suppliers, and authorities," Taco Bell said in a statement.

Taco Bell said it has voluntarily removed the suspected lettuce from its supply chain nationwide "indefinitely" and will replace it in selected states within the next day.

The FDA is investigating iceberg lettuce supplied to Taco Bell by Taylor Farms as a possible source of the outbreak, per NBC News. Taylor Farms did not immediately respond to a request for comment.

MDHHS is urging restaurants and commercial kitchens in southeast Michigan to take extra precautions with fresh produce — washing under clean running water and cooking whenever possible. "If you can cook it or peel it, it's much safer," health officials said.

The CDC is investigating clusters of cases linked across Michigan, Ohio, West Virginia, and Kentucky.

Michigan cases have grown to 3,762 as of July 15th, up significantly from 2,600+ earlier this week, per MDHHS.

Taco Bell has pulled ingredients including, but not limited to lettuce, pico de gallo, cilantro-based items and guacamole.

Taco Bell said in a statement that it has "voluntarily and temporarily removed limited ingredients at select restaurants as a precautionary measure," while noting that public health authorities have not officially confirmed a link to Taco Bell or any specific ingredient, supplier, restaurant, or retailer.

Taco Bell is being investigated by federal and state health officials for a potential role in the outbreak, per the Washington Post. Some patients told investigators they had eaten at Taco Bell — though others said they had not.

Michigan alone has reported 3,309 cases as of July 14 — over 65 times its annual average of 40-50 cases per year.

As of July 14, nearly 7,000 confirmed and probable cases of cyclosporiasis have been reported across 34 states, per the CDC and state health departments. No deaths have been reported at this time.

More than 1,000 patient interviews have been completed as part of the ongoing investigation.

Other food items cannot be completely ruled out as a source, health officials cautioned.

"Although we do not have a definite product identified as the source of the outbreak, we want to let Michiganders know what we have learned so far so they can take steps to protect their families," said Dr. Natasha Bagdasarian, chief medical executive for MDHHS.

The Michigan Department of Health and Human Services (MDHHS) announced Monday that early investigation results "point to lettuce or salad greens as a potential source for this outbreak." No specific produce, grower, or supplier has been identified.

Michigan cases have surged to over 2,600 — up from 1,562 just days ago. Michigan typically records only 40-50 cases of cyclosporiasis annually.

Local, state, and federal authorities including the CDC and FDA are investigating several clusters of cases across more than one state. Investigations to identify the source are ongoing.

Multiple states have reported an increase in cases over the last two weeks compared to the same period in 2025. The CDC anticipates case counts will continue to rise due to a 6-week reporting lag between illness onset and case reporting.

Cases have been reported in people aged 5 to 88-years-old, according to the CDC.

Michigan, which has the highest case count of any state, has reported 1,562 total cases as of July 10, per the Michigan Department of Health and Human Services. 44 Michigan cases have required hospitalization. The source of the outbreak has not been identified. MDHHS updates case counts daily Monday through Friday.

Officials urge washing all produce thoroughly under running water, buying whole heads of lettuce rather than pre-bagged mixes, and discarding outer leaves. Anyone with sudden, ongoing diarrhea should see a provider and ask specifically for cyclosporiasis testing, since standard stool panels can miss it.

Health officials have not identified a source. Contaminated fresh produce is the leading hypothesis; past cyclosporiasis outbreaks have been linked to basil, cilantro, raspberries, snow peas, and bagged salad greens. No recall has been issued.

Other states are also reporting rising counts, including Ohio (about 177), New York, and Illinois. The CDC's most recent national surveillance count is 145 cases across 17 states through June 16—a figure that predates and does not include the Michigan surge.

Michigan remains the epicenter, with cases concentrated in the southeast: Monroe, Lenawee, Washtenaw, Wayne, Shiawassee, Jackson, Oakland, and Livingston counties. The state normally sees about 50 cases in an entire year.

Michigan's case count is now at 1,251 as of July 9, per MDHHS. 44 of those cases were hospitalized.

In a press release, the Houston Health Department has reported 16 confirmed cases of cyclosporiasis in the City of Houston, in addition to 18 confirmed cases via the Harris County Public Health Department.

In Michigan, 36 people have been hospitalized. No deaths have been reported nationally.

A total of 21 states are included: Alabama, Alaska, Colorado, Connecticut, Florida, Georgia, Illinois, Kentucky, Louisiana, Massachusetts, Michigan, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia, West Virginia, and Wisconsin.

Health officials in Michigan have reported over 700 cases in a recent surge of people sickened across the state.

Cyclosporiasis causes intestinal illnesses, with symptoms that can persist between periods of brief recovery.

The cause has not been linked to a single source, and officials expect a peak seasonality of people sickened by the parasite in the summertime.

The CDC is tracking an outbreak of the parasite cyclosporiasis across multiple states.

Incident reported at United States.

This compares to just 1,180 cases reported during the same period last year, meaning this year's outbreak is running more than 13 times the historical pace.

The CDC's national case count has grown to 15,716 laboratory-confirmed cases since May 1, with an additional 11,841 cases under investigation — bringing the total to roughly 27,500 nationwide.

Officials cautioned that because of a roughly six-week reporting lag, the national total will likely keep rising even as case growth slows.

New infections now appear to be slowing.

The FDA is investigating six separate cyclosporiasis outbreaks in total. Officials caution that not all cases are linked to a single nationwide source — several smaller, distinct outbreaks may be occurring simultaneously.

Nationally, cases have now been reported in 47 states, with 517 hospitalizations and 2 deaths.

The CDC is expanding the largest known cyclosporiasis outbreak — linked to Taylor Farms lettuce — to 15 states, adding Arkansas, Iowa, Missouri, Nebraska, New Hampshire, and North Carolina, according to The Washington Post. Missouri alone has reported more than 1,000 cases.

As of August 5, the death toll remains at two — both reported in Michigan on August 3 — with no additional deaths confirmed nationally.

Additionally, Michigan's case count has grown to 11,508 as of the state's latest update, up from 11,234 on August 3. 193 people have been hospitalized since the outbreak began.

The CDC's laboratory-confirmed case count has grown to 10,468 since May 1, up from 6,707 just days earlier. An additional 12,255+ cases are under investigation, bringing the total estimated case count to more than 22,700 nationwide.

Officials said that both of the people who died had "significant underlying health conditions" that may have been impacted by the illness and ensuing dehydration.

Additionally, the first two deaths in this outbreak have been reported in Michigan.

Michigan's case count has grown to 11,234 as of August 3, with 193 hospitalizations, per MDHHS.

Federal health officials continue to investigate, believing there could be multiple cyclosporiasis outbreaks from different sources beyond the one linked to Taylor Farms iceberg lettuce, according to Harvard T.H. Chan School of Public Health.

Michigan's case count has grown to 10,386 as of July 30, with 193 hospitalizations, per MDHHS.

This is now considered the largest known outbreak of cyclosporiasis in US history, per The Hill.

Michigan remains the hardest hit with more than 10,077 cases, followed by Ohio with more than 2,600 reported cases. There have been 423 hospitalizations nationally and no deaths.

The CDC added Oregon, South Dakota, Vermont, and Delaware to its list of states reporting cases in its latest update.

Cases have now been reported in 45 states, with only Hawaii, Maine, Montana, New Mexico, and South Carolina reporting no cases connected to the domestic outbreak, per the CDC's July 28 update.

Michigan remains the hardest-hit state with 9,680 cases and 160 hospitalizations. Ohio, North Carolina, Illinois, Indiana, New York, Oklahoma, West Virginia, Arkansas, and Missouri have also reported cases in the hundreds or thousands.

The CDC's national surveillance count has grown to 6,707 laboratory-confirmed cases since May 1, with more than 11,500 additional illnesses still awaiting confirmation. States report a combined total of at least 17,812 cases — nearly 18,000 people, or four to five times the total case count seen in all of 2025.

Taylor Farms maintains there have been no confirmed positive test results for cyclospora in its products as of July 24. The company said it acted quickly, removing all potentially implicated product from the marketplace once questions were raised.

Michigan's case count has topped 9,200 as of July 27, up from 8,176 just days earlier, per state health officials.

Michigan alone has reported 8,176 cases as of July 23 — up from 6,571 — with 160 hospitalizations, per MDHHS.

The CDC's Taco Bell-specific outbreak has grown to 1,947 confirmed cases across 9 states as of July 24 — up from 1,644. Four states have been added to the outbreak: Illinois, Kansas, Oklahoma, and Pennsylvania. Illness onset dates range from June 22 through July 20.

Reuters reported an additional 72 people with the illness in a new cluster not previously linked to the current outbreak.

Per ABC News, reporting numbers have an average six-week delay between case reporting.

An update from the CDC has increased the number of confirmed cases to over 11,500, now spanning 41 states.

MDHHS recommends buying whole heads of lettuce rather than pre-washed bagged lettuce or pre-mixed salad kits. Before preparation, discard the outer two to three layers of leaves and wash remaining inner leaves thoroughly under clean running water.

HHS Secretary Robert F. Kennedy Jr. Said Tuesday the cyclosporiasis outbreak is "under control" and cast doubt on the link to Taylor Farms lettuce and Mexico, while the FDA's voluntary recall of Taylor Farms iceberg lettuce from central Mexico remains in effect.

North Carolina reported 307 cases as of July 17. Wake County has reported the highest number of cases in the state, with 295 as of July 20.

The CDC expects illnesses to continue increasing through the end of August, when the typical Cyclospora season ends. Cases have been identified in 34 states.

Michigan cases have risen to 6,571 as of July 21, up from 6,148 the previous day, per MDHHS. Cases remain highest in Monroe, Lenawee, Washtenaw, Wayne, Shiawassee, Jackson, Oakland and Livingston counties.

New York state has reported 576 cases since May 1 — up from 470 earlier this month, per NYSDOH Commissioner Dr. Jim McDonald. Approximately 70% of New York cases are from the New York City area. "New York isn't one of the five states linked to the Taco Bell-specific cluster, so we still don't know the source" for New York cases, McDonald said.

The FDA is continuing to test lettuce samples and produce at the southern border. So far, no positive test results have been found. The investigation remains ongoing and officials say multiple clusters may have separate sources.

Taylor Farms said the FDA apologized, noting "FDA has not identified a single positive product test result for Cyclospora." The company confirmed it is no longer sourcing iceberg lettuce from central Mexico for the remainder of the growing season and is continuing to work with public health officials.

The FDA announced Sunday that a previous laboratory test identifying Cyclospora in a Taylor Farms lettuce sample was a false positive. "The finding does not represent true amplification," the FDA said in a statement. However, the FDA clarified the false positive "does not change the basis for FDA's ongoing outbreak investigation or the overwhelming epidemiological data supporting the current voluntary recall by Taylor Farms," per NPR.

The FDA has increased border screening for products implicated in the outbreak. Additional brands, restaurants, or distribution channels may be identified as the investigation continues.

Taylor Farms said it has stopped receiving product from the implicated lot, suspended distribution of iceberg lettuce from Central Mexico, and notified its customers. The company is continuing to work with the FDA, CDC, and state authorities.

The recall covers multiple iceberg lettuce and lettuce blend products sold under several brand codes including CV, MARK, MKTSD, TF, SY, PK, JB, and SUB. Retail products include Iceberg Salad (12 oz, 24 oz) and Shredded Lettuce (8 oz, 16 oz) with use-by dates ranging from July 18 to August 3, 2026.

Taylor Farms distributed the implicated shredded iceberg lettuce from June 29 through July 16 across 27 states - AL, AR, CT, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, MI, MO, MS, NC, NH, NJ, OH, OK, PA, SC, TN, TX, VA, and WI.

Do not eat shredded iceberg lettuce from Taylor Farms at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia.

Of those interviewed, 90% reported eating iceberg lettuce at Taco Bell before becoming ill.

The FDA and CDC have confirmed 1,644 cases linked specifically to Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia. 94 people have been hospitalized. No deaths have been reported in the Taco Bell-specific outbreak.

On July 17, Taylor Farms announced a voluntary recall of all iceberg lettuce sourced from central Mexico from the US market.

The FDA has officially confirmed that Taylor Farms is the single supplier of shredded iceberg lettuce linked to the 5-state Taco Bell outbreak, per its traceback investigation.

This is not the first time Taylor Farms has been connected to a food safety outbreak. The company was linked to a 2013 cyclosporiasis outbreak affecting 631 people in 25 states, and a 2024 E. coli outbreak tied to McDonald's Quarter Pounders that killed one person.

Michigan now has 4,312 confirmed cases and 102 hospitalizations as of Thursday — up from 3,762 earlier this week. Indiana has emerged as part of the multi-state outbreak, joining Michigan, Ohio, West Virginia, and Kentucky.

"We believe public health is a shared responsibility among restaurants, their suppliers, and authorities," Taco Bell said in a statement.

Taco Bell said it has voluntarily removed the suspected lettuce from its supply chain nationwide "indefinitely" and will replace it in selected states within the next day.

The FDA is investigating iceberg lettuce supplied to Taco Bell by Taylor Farms as a possible source of the outbreak, per NBC News. Taylor Farms did not immediately respond to a request for comment.

MDHHS is urging restaurants and commercial kitchens in southeast Michigan to take extra precautions with fresh produce — washing under clean running water and cooking whenever possible. "If you can cook it or peel it, it's much safer," health officials said.

The CDC is investigating clusters of cases linked across Michigan, Ohio, West Virginia, and Kentucky.

Michigan cases have grown to 3,762 as of July 15th, up significantly from 2,600+ earlier this week, per MDHHS.

Taco Bell has pulled ingredients including, but not limited to lettuce, pico de gallo, cilantro-based items and guacamole.

Taco Bell said in a statement that it has "voluntarily and temporarily removed limited ingredients at select restaurants as a precautionary measure," while noting that public health authorities have not officially confirmed a link to Taco Bell or any specific ingredient, supplier, restaurant, or retailer.

Taco Bell is being investigated by federal and state health officials for a potential role in the outbreak, per the Washington Post. Some patients told investigators they had eaten at Taco Bell — though others said they had not.

Michigan alone has reported 3,309 cases as of July 14 — over 65 times its annual average of 40-50 cases per year.

As of July 14, nearly 7,000 confirmed and probable cases of cyclosporiasis have been reported across 34 states, per the CDC and state health departments. No deaths have been reported at this time.

More than 1,000 patient interviews have been completed as part of the ongoing investigation.

Other food items cannot be completely ruled out as a source, health officials cautioned.

"Although we do not have a definite product identified as the source of the outbreak, we want to let Michiganders know what we have learned so far so they can take steps to protect their families," said Dr. Natasha Bagdasarian, chief medical executive for MDHHS.

The Michigan Department of Health and Human Services (MDHHS) announced Monday that early investigation results "point to lettuce or salad greens as a potential source for this outbreak." No specific produce, grower, or supplier has been identified.

Michigan cases have surged to over 2,600 — up from 1,562 just days ago. Michigan typically records only 40-50 cases of cyclosporiasis annually.

Local, state, and federal authorities including the CDC and FDA are investigating several clusters of cases across more than one state. Investigations to identify the source are ongoing.

Multiple states have reported an increase in cases over the last two weeks compared to the same period in 2025. The CDC anticipates case counts will continue to rise due to a 6-week reporting lag between illness onset and case reporting.

Cases have been reported in people aged 5 to 88-years-old, according to the CDC.

Michigan, which has the highest case count of any state, has reported 1,562 total cases as of July 10, per the Michigan Department of Health and Human Services. 44 Michigan cases have required hospitalization. The source of the outbreak has not been identified. MDHHS updates case counts daily Monday through Friday.

Officials urge washing all produce thoroughly under running water, buying whole heads of lettuce rather than pre-bagged mixes, and discarding outer leaves. Anyone with sudden, ongoing diarrhea should see a provider and ask specifically for cyclosporiasis testing, since standard stool panels can miss it.

Health officials have not identified a source. Contaminated fresh produce is the leading hypothesis; past cyclosporiasis outbreaks have been linked to basil, cilantro, raspberries, snow peas, and bagged salad greens. No recall has been issued.

Other states are also reporting rising counts, including Ohio (about 177), New York, and Illinois. The CDC's most recent national surveillance count is 145 cases across 17 states through June 16—a figure that predates and does not include the Michigan surge.

Michigan remains the epicenter, with cases concentrated in the southeast: Monroe, Lenawee, Washtenaw, Wayne, Shiawassee, Jackson, Oakland, and Livingston counties. The state normally sees about 50 cases in an entire year.

Michigan's case count is now at 1,251 as of July 9, per MDHHS. 44 of those cases were hospitalized.

In a press release, the Houston Health Department has reported 16 confirmed cases of cyclosporiasis in the City of Houston, in addition to 18 confirmed cases via the Harris County Public Health Department.

In Michigan, 36 people have been hospitalized. No deaths have been reported nationally.

A total of 21 states are included: Alabama, Alaska, Colorado, Connecticut, Florida, Georgia, Illinois, Kentucky, Louisiana, Massachusetts, Michigan, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia, West Virginia, and Wisconsin.

Health officials in Michigan have reported over 700 cases in a recent surge of people sickened across the state.

Cyclosporiasis causes intestinal illnesses, with symptoms that can persist between periods of brief recovery.

The cause has not been linked to a single source, and officials expect a peak seasonality of people sickened by the parasite in the summertime.

The CDC is tracking an outbreak of the parasite cyclosporiasis across multiple states.
