Cyclosporiasis Outbreak Linked to Taco Bell Lettuce Supplier 2026

The cyclosporiasis outbreak linked to Taco Bell lettuce from Taylor Farms has raised concerns across the U.S., with federal health officials investigating the source of the parasitic illness that has sickened thousands. As of late July, the CDC reported 1,645 lab-confirmed cases and 145 hospitalizations, with a backlog of 5,100 cases still under analysis.

What Is Cyclosporiasis?

Cyclosporiasis is an intestinal infection caused by the parasite Cyclospora cayetanensis. It leads to watery, explosive diarrhea, fatigue, and stomach cramps. The illness is typically spread through contaminated food or water, especially fresh produce like lettuce.

How It Spreads

The parasite is not contagious from person to person. Instead, people contract it by consuming food or water contaminated with microscopic parasite oocysts. Iceberg lettuce from Taylor Farms, supplied to Taco Bell, is now under scrutiny as a potential vehicle.

CDC Data and Current Status

The CDC expects the outbreak to continue into August, with the true number of infections likely higher due to mild cases going unreported. Gwen Biggerstaff, deputy director of the CDC’s division of foodborne diseases, noted, “We’re seeing an unusually high number of cyclosporiasis cases this summer.”

Taco Bell’s Response

Taco Bell voluntarily removed potentially impacted lettuce from select states and is replacing it within 24 hours. The company stated, “Based on ongoing conversations with public health officials, and out of an abundance of caution, Taco Bell has taken immediate action.” The ingredient has been indefinitely removed from the national supply chain.
