Federal and state health officials are reportedly investigating Taco Bell as a potential source of a widespread cyclosporiasis outbreak that has sickened at least 2,640 people in Michigan alone. The investigation comes as cases nationwide are surging significantly above typical levels, with 38 states confirming domestic and international cases.
Health officials in Michigan have identified lettuce or salad greens as a possible source, though no specific grower or supplier has been identified. Dr. Natasha Bagdasarian, chief medical executive of the Michigan Department of Health and Human Services, stated that early information frequently points to lettuce as a common product under investigation.
Last week, Taco Bell removed several ingredients from its menu, including lettuce, pico de gallo, guacamole, and cilantro onion, citing a "nationwide recall." Notices posted at some U.S. locations, including in Michigan, informed customers that items normally containing these ingredients would be served without them. The company has not publicly confirmed the reason for the ingredient removal or whether it is connected to the outbreak. No official food recalls have been issued in relation to the cyclosporiasis cases.
Cyclosporiasis is an intestinal infection caused by the cyclospora parasite. Symptoms, which typically appear about a week after exposure, include sudden and severe gastrointestinal issues such as diarrhea, cramping, nausea, vomiting, and fatigue. The infection can last for over a month if untreated, with symptoms potentially recurring. It is typically contracted by consuming contaminated food or beverages, often linked to feces. Human-to-human transmission is rare.
While the Centers for Disease Control and Prevention (CDC) data shows over 1,500 cases requiring further analysis, 38 state health departments have reported nearly 4,000 confirmed cases. Michigan, which typically sees 40 to 50 cases annually, is experiencing an unprecedented surge. Health officials are emphasizing the need for greater coordination between state and federal agencies to identify the outbreak's source.
Previous cyclosporiasis outbreaks in the U.S. have been linked to bagged salad mixes, fresh cilantro, basil, raspberries, snow peas, and green onions. The CDC recommends preventing infection by avoiding food and water at risk of fecal contamination and adhering to general food safety practices. Treatment usually involves a course of antibiotics, though most individuals with healthy immune systems recover without medical intervention.
