Taco Bell lettuce linked to cyclospora outbreak across five Midwest states
At least 1,644 confirmed or suspected cases of cyclosporiasis across five states with 141 hospitalizations; symptoms include severe watery diarrhea, cramping, and bloating lasting weeks.
The largest cyclospora outbreak in US history, unfolding in real time

Why does lettuce keep showing up in these outbreaks? Is there something about how it's grown or handled?
Mimi
Lettuce is eaten raw, which means there's no cooking step to kill parasites or bacteria. Once it's contaminated in the field or during processing, it stays that way until someone eats it. That's why fresh produce outbreaks tend to be so widespread—one contaminated batch can reach thousands of people before anyone realizes there's a problem.
Mark
Taylor Farms has been involved in outbreaks before. How does a supplier stay in business after multiple incidents?
Mimi
Size and geography work in their favor. They supply so many restaurants and stores across the country that any single outbreak, even a large one, affects only a portion of their business. And the food industry's memory is short—unless a company is repeatedly implicated in the same type of failure, they can usually recover. But this pattern does raise questions about their safety protocols.
Mark
What does it mean that Michigan has 4,300 cases but only 1,644 are officially linked to Taco Bell?
Mimi
The state is still investigating. Some of those cases might be from other sources entirely—maybe contaminated lettuce from a grocery store, or a different outbreak altogether. The health department is being careful not to overstate the connection until they have solid evidence. But the timing and concentration suggest most of them are probably related.
Mark
How long will people stay sick?
Mimi
Weeks, potentially. The parasite causes your intestines to become inflamed, and that takes time to resolve even with treatment. For most people it's not dangerous, but it's genuinely miserable—imagine severe stomach cramps and diarrhea that won't quit for a month.
Mark
What happens to Taylor Farms now?
Mimi
That depends on what the FDA finds. If contaminated lettuce is still in the supply chain, there could be recalls and legal action. But the company's real vulnerability is reputational. Consumers remember these incidents, and restaurants get nervous about their suppliers. One more outbreak and they could lose significant business.
Der Puls
- A parasitic illness is spreading across Indiana, Kentucky, Michigan, Ohio, and West Virginia at a pace that has overwhelmed local health departments and sent 141 people to hospitals.
- Michigan alone has logged more than 4,300 cases under investigation, suggesting the true scale of the outbreak may dwarf the confirmed numbers.
- Taylor Farms, the supplier at the center of the contamination, has a prior history with food safety failures — including E. coli and cyclospora-linked incidents — raising urgent questions about systemic gaps in produce safety.
- Taco Bell has pulled the affected lettuce from its entire national supply chain and is racing to replace it within 24 hours, but the contaminated product had already been widely distributed before the warning was issued.
- The FDA is still working to determine whether tainted lettuce remains in circulation elsewhere, while health officials urge anyone who ate at these locations and fell ill to report their symptoms immediately.
A microscopic parasite has quietly moved through the food supply, turning an ordinary fast food meal into a public health crisis spanning five Midwestern states. Shredded iceberg lettuce served at Taco Bell locations — grown in Mexico and distributed by Taylor Farms — has been linked to what may be the largest cyclospora outbreak in American history, with nearly 1,644 confirmed or suspected cases and 141 hospitalizations. The event is a reminder that the distance between a farm and a dinner table is rarely as simple as it appears, and that the invisible world of pathogens does not respect the boundaries of convenience or scale.
Federal health officials this week warned the public not to eat shredded iceberg lettuce at Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio, and West Virginia, after the ingredient was linked to a cyclospora outbreak that may be the largest in American history. At least 1,644 cases have been confirmed or are under investigation across the five states, with 141 hospitalizations recorded. Michigan alone has reported more than 4,300 cases as part of the broader inquiry. Since May 1, nearly 7,000 cases of cyclosporiasis have been confirmed or investigated nationally, though the current crisis appears concentrated in this Midwest cluster.
The lettuce was grown in Mexico and supplied by Taylor Farms, a major national produce distributor with a documented history of food safety incidents, including E. coli cases tied to slivered onions in 2024 and a prior cyclospora-linked lettuce outbreak in 2013. The company did not respond to requests for comment. Cyclosporiasis, caused by a microscopic parasite in contaminated food or water, does not pass between people but produces weeks of severe watery diarrhea, cramping, and bloating — symptoms that have strained health resources across the region.
Michigan health officials interviewed more than 1,000 people to trace the source, and while they cannot confirm with absolute certainty that every case shares the same origin, the concentrated geographic and temporal spike points strongly to a single exposure. Taco Bell moved quickly once the link was established, voluntarily removing the lettuce from its full national supply chain and promising replacement product from a different supplier within 24 hours.
The FDA is continuing to investigate whether any contaminated lettuce remains in circulation at other locations or retailers. Health officials are asking anyone who ate lettuce at Taco Bell in the five affected states and developed gastrointestinal symptoms to contact their local health department.
Federal health officials issued an urgent warning this week: do not eat shredded iceberg lettuce at Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio, and West Virginia. The lettuce has been linked to a cyclospora outbreak that is spreading across the Midwest with alarming speed, potentially marking the largest outbreak of this parasitic illness in American history.
The numbers are staggering. At least 1,644 cases have been confirmed or are under investigation across the five affected states, with Michigan alone reporting more than 4,300 cases as part of the broader investigation. The CDC and FDA have documented at least 141 hospitalizations. Nationally, the picture is even wider: since May 1, nearly 7,000 cases of cyclosporiasis have been confirmed or are being investigated across the country, though most of the current outbreak appears concentrated in this Midwest cluster.
The contaminated lettuce came from Taylor Farms, a major produce supplier that sources products to grocery stores and restaurants nationwide. The lettuce was grown in Mexico. Taylor Farms did not respond to requests for comment, but the FDA is now working to determine whether additional contaminated product remains in the supply chain. The company's involvement in food safety issues is not new—Taylor Farms produce has been linked to previous outbreaks, including E. coli cases tied to slivered onions in 2024 and cyclospora cases associated with lettuce in 2013.
Cyclosporiasis is caused by a microscopic parasite that contaminates food or water; it does not spread directly between people. Those infected experience watery diarrhea, cramping, and bloating that can persist for weeks. The illness is not typically severe enough to be life-threatening, but the sheer volume of cases has strained public health resources and sent people to hospitals across the region.
Michigan's state health department has been at the center of the investigation, interviewing more than 1,000 people to trace the source. Officials acknowledged they cannot say with absolute certainty that every case stems from the same exposure, but the sharp, concentrated spike in illnesses strongly suggests the vast majority are connected. The timing and geography of the outbreak point unmistakably to a single source.
Taco Bell responded quickly once the connection became clear. The company announced it had voluntarily removed the affected lettuce from select states and is removing the ingredient from its entire supply chain indefinitely. Replacement lettuce from a different supplier will arrive within 24 hours in the affected states. The speed of the response underscores how seriously the company is treating the situation, though it also highlights how widely distributed the contaminated product may have been before the warning went out.
The FDA continues investigating whether contaminated lettuce from this supplier remains on shelves or in restaurant kitchens elsewhere in the country. Multiple investigations are underway simultaneously—some tied to this large Midwest outbreak, others involving single states, and still others tracking cases not yet connected to any known cluster. As the investigation unfolds, health officials are asking anyone who consumed lettuce from Taco Bell in these five states during the relevant period and developed gastrointestinal symptoms to contact their local health department.
