A parasite outbreak that began with contaminated lettuce at Taco Bell has ballooned into the largest cyclosporiasis investigation in history, with authorities now tracking more than 11,500 suspected cases across nine states.
The Centers for Disease Control and Prevention confirmed 4,173 laboratory-verified cases this week and is investigating an additional 7,400 suspected infections. The expansion marks a dramatic escalation from the original five-state cluster that prompted food safety alerts in early summer.
Iceberg lettuce supplied by Taylor Farms de Mexico has been identified as the source of infections in Indiana, Kentucky, Michigan, Ohio and West Virginia. The company issued a voluntary recall after the link became clear. Investigation efforts now extend to Illinois, Kansas, Oklahoma and Pennsylvania as officials work to determine whether additional shipments from the same supplier caused illness elsewhere.
Cyclosporiasis results from infection by cyclospora, a single-celled parasite that contaminates raw produce when it comes into contact with human feces. The illness triggers severe, watery diarrhea that can persist for weeks or longer. No specific medications target the infection, making prevention through food safety the critical line of defense.
The FDA is separately investigating 72 cyclosporiasis cases that have not yet been connected to a specific food product or supplier. Previous regional outbreaks have traced infections to parsley and cilantro, highlighting the vulnerability of raw produce across the food supply.
Health officials are urging consumers who purchased iceberg lettuce from the affected distributor during the summer months to avoid consumption and report any symptoms of severe diarrhea to local health departments. The investigation remains ongoing as the CDC works to identify any additional contaminated sources.
Author James Rodriguez: "This is the kind of outbreak that exposes how fragile our food safety systems are when produce travels internationally and sits in distribution for days before reaching plates."
