Iceberg lettuce sold at Taco Bell linked to cyclospora outbreak, sources say
Shredded iceberg lettuce supplied by Taylor Farms and sold at some Taco Bell restaurants has been linked to a multistate outbreak of cyclosporiasis, a source familiar with the investigation told CNN Thursday.
The Washington Post also reports that two sources familiar with the matter also say lettuce sold at some of the popular restaurant’s locations have been linked to the outbreak.

Cases of the intestinal illness caused by a microscopic parasite are surging across the US, with nearly 7,000 cases confirmed or under investigation since May 1, according to data published Tuesday by the CDC. Confirmed cases alone are more than six times higher than they were at this time last year, and there have been at least 141 hospitalizations.
The outbreak linked to the lettuce, however, is considered to be a regional one, centered in the Midwest.
The CDC has identified at least 400 cases associated with the outbreak across four states – Michigan, Ohio, West Virginia and Kentucky – and the source told CNN that those states are where the affected Taco Bell locations are. However, they noted that the produce may have also gone to other places.
The Michigan state health department has reported more than 4,300 cases of cyclospora during the outbreak investigation. Michigan said it has interviewed more than 1,000 people as part of its investigation and had previously noted that lettuce or salad greens may be a potential source for the outbreak.
The state health department said that it “cannot say with certainty that every illness is linked to the same source of exposure” but that the concentrated, sharp increase in cases “strongly suggests that the vast majority of these illnesses are associated with the same outbreak.” This would make it the largest cyclospora outbreak in the US on record.
Neither Taco Bell nor Taylor Farms has responded to CNN’s request for comment Thursday.

Cyclosporiasis is not usually spread directly from person to person. Instead, people can become infected by consuming contaminated food or water. Previous outbreaks have been linked to fresh produce, the CDC says.
People with cyclosporiasis may have symptoms that include watery diarrhea, cramping and bloating for weeks.
Federal health officials said there are multiple investigations underway, some tied to the large outbreak in the Midwest, some involving single states and some involving cases not yet tied to any cluster.
Taylor Farms supplies grocery stores and restaurants across the country, although it’s unclear exactly how many of its products and which locations may be affected.
Taco Bell said Tuesday that it was removing some ingredients from its menu at some restaurant locations as a precaution.
“While authorities continue their broader review, Taco Bell has voluntarily and temporarily removed limited ingredients at select restaurants as a precautionary measure,” Taco Bell Corp. said in a statement. “We will continue to closely monitor the situation and follow the guidance of public health authorities.”
Taylor Farms produce has also been linked with previous illness outbreaks, including E. coli cases tied to slivered onions in 2024 and cyclospora cases linked with lettuce in 2013.
