At least 1,947 people infected with Cyclospora who had exposure to Taco Bell have been reported in nine states. Michigan and Ohio are together reporting more than 10,000 cyclosporiasis cases. FDA is investigating three other outbreak clusters.
The growing collection includes scientific publications and guidances on detection and viability methods, agricultural water monitoring and treatment, mitigation strategies, and the biology and epidemiology of the parasite.
Several senators have written letters to U.S. Health Secretary Kennedy urging Cyclospora surveillance to be restored to the FoodNet program. Experts say that FoodNet cuts, although problematic, did not cause the current outbreak.
By the same time last year, CDC had only reported 249 confirmed, domestically acquired Cyclospora infections across the entire U.S. States’ reports may include both probable and confirmed cases.
Between 1,600 and 5,000 people are sick in a five-state cyclosporiasis outbreak, according to CDC and Michigan officials. Iceberg lettuce supplied by Taylor Farms of Mexico to companies like Taco Bell and Walmart has been identified as the vehicle of infection. FDA has rescinded a previous positive product sample finding.
The outbreak cluster includes more than 1,600 people in Indiana, Kentucky, Michigan, Ohio, and West Virginia. Outside of the outbreak cluster, Michigan and other parts of the U.S. continue to experience elevated rates of Cyclospora infections compared to previous years.
Public health experts say the ongoing cyclosporiasis situation exposes growing weaknesses in national foodborne illness surveillance, highlighting how funding and program cuts and CDC staff attrition could undermine outbreak detection and delay response, affecting public health communication and consumer confidence in food safety.
In a letter, Senator Amy Klobuchar urged CDC and FDA to fully restore food safety programs that have been affected under the Trump Administration and continue supporting state public health agencies with the resources needed to detect, investigate, and respond to foodborne illness outbreaks.
More than 400 cases in Michigan, Ohio, Kentucky, and West Virginia appear to be epidemiologically linked, although a food source has not been confirmed. Michigan alone reports more than 3,300 Cyclospora infections.
Per CDC, 843 domestically acquired cyclosporiasis cases have been confirmed in 31 states, plus another 1,500 pending analysis. Michigan alone has reported more than 2,600 cases and is looking at lettuce as a potential vehicle of illness.
