Federal health officials have expanded their investigation into a significant cyclosporiasis outbreak, now linking the illness to shredded iceberg lettuce served at Taco Bell restaurants across nine states. The Centers for Disease Control and Prevention and the Food and Drug Administration confirmed that the outbreak, which has sickened 1,947 people, now includes Illinois, Kansas, Oklahoma, and Pennsylvania, joining Indiana, Kentucky, Michigan, Ohio, and West Virginia. While there have been no reported deaths, at least 98 people have required hospitalization due to the infection.
Cyclosporiasis is a gastrointestinal illness caused by the microscopic parasite Cyclospora cayetanensis. The parasite typically enters the body through the consumption of contaminated food or water. Symptoms often include watery diarrhea, fatigue, loss of appetite, and stomach cramps. Because these symptoms can mimic other common illnesses, health officials emphasize that routine stool tests do not always screen for the parasite, and patients may need to specifically request testing if they suspect an infection.
In response to the investigation, Taylor Farms de Mexico, the supplier identified by federal authorities, initiated a voluntary recall of all iceberg lettuce sourced from central Mexico. The recall encompasses products distributed to retail stores, restaurants, and various food service customers. Taco Bell has confirmed that it ceased using lettuce from the affected supplier as of July 17, 2026.
Investigators are continuing to interview patients to track the movement of the contaminated product through the supply chain. Officials warn that the total number of cases is likely higher than the current tally, as some individuals may recover without seeking medical care. Furthermore, because it can take up to six weeks to confirm whether a specific case is linked to this outbreak, experts anticipate that the number of confirmed illnesses will continue to rise in the coming weeks.
