A food safety scare just got bigger. The microscopic parasite was present in shredded iceberg lettuce from Taylor Farms, a large produce distributor that supplies Walmart, Target, Whole Foods, and Taco Bell.
Symptom onset for the majority of patients linked to the contaminated lettuce occurred from June 22 to July 20, though initial cases emerged in mid-May. That lag matters. Cyclospora has a long incubation period, meaning the contaminated lettuce was already on store shelves and in restaurant kitchens weeks before anyone knew there was a problem. The crop that caused it is long gone by now.
But for a parasite that normally infects only roughly 200 to 1,000 people across the entire country in a given year, this spike is massive - well above the usual annual count, with thousands of illnesses recorded nationwide.

The outbreak is already linked to a specific product line. The FDA indicated that the large produce distributor supplied the Taco Bell locations frequented by the patients with the contaminated iceberg lettuce. The produce company has faced public backlash over how it handled the recall.
Critics pointed out that the recall notice used confusing acronyms, making it difficult for consumers to determine whether they purchased or consumed any affected items. On Sunday, the FDA announced a false positive test result on lettuce from Taylor Farms; in response, the company released a statement claiming the agency had issued an apology.
Subsequently, the FDA denied having apologized, and Taylor Farms removed its post from X, though the statement remains on the company's website. The FDA continues to regard Taylor Farms' iceberg lettuce as the probable origin of the outbreak.
Taylor Farms is a key supplier of lettuce and other vegetables to large retailers like Walmart, Target, and Whole Foods, along with restaurant chains such as Taco Bell.
Health officials are still hunting for the exact source of the parasite. On Thursday, Mexican health officials reported that tests on lettuce and water samples taken from the Taylor Farms facility in central Mexico came back negative for cyclospora. Nevertheless, this negative finding does not invalidate the FDA's previous determination that Taylor Farms de Mexico is the probable culprit. Separately, the FDA is probing another cyclosporiasis outbreak that has been tied to an as-yet-unknown food item or items.
Federal authorities are working to identify the parasite's origins and limit its transmission, all while facing criticism over their handling of the outbreak and recent staff reductions that, according to some specialists, have hindered containment efforts. For consumers and businesses watching the situation, the timeline for resolution remains uncertain. The investigation is still open, and the case count continues to climb.
