FDA investigates new cyclospora outbreak

The U.S. United States — Food and Drug Administration announced on July 22, 2026, that it is investigating a new outbreak of cyclospora parasite infections, with 72 cases linked to an unknown source. This adds to a surge of cases centered in the Midwest, previously linked to Taylor Farms lettuce, which led to a recall. The FDA is also examining several other ongoing cyclospora clusters. The outbreaks have impacted consumer confidence and investor sentiment, causing stock declines for Sweetgreen, Chipotle Mexican Grill, and Yum! Brands, though none of these companies have been directly linked to the new outbreak. The CDC reports thousands of infections across 41 states this summer, with at least 300 hospitalizations. The parasite is difficult to trace, and the FDA's investigation continues.
