- U.S. health officials declared the largest cyclospora food poisoning outbreak in U.S. history over on Friday, though nearly 13,000 reported cases were tied to the multistate outbreak
- The FDA is confident all recalled iceberg lettuce linked to the outbreak is off the market, and investigators traced the contamination to Taylor Farms, which recalled iceberg lettuce grown in central Mexico
- The recalled products were shipped to major restaurant chains including Yum Brands' Taco Bell, Pizza Hut, and KFC, after investigators initially zeroed in on Taco Bell-served lettuce
- Michigan was the hardest-hit state, recording the most reported cases and both U.S. deaths tied to the outbreak, which spanned 21 states
- The broader 2025 surge has produced nearly 20,000 lab-confirmed cyclospora cases since May 1—more than 16 times the same period last year and surpassing the previous U.S. record of 4,700 cases set in 2019
- The contamination pathway remains a mystery; cyclospora spreads through human feces and can infect produce via contaminated soil or water, but investigators haven't determined how sewage tainted enough food to cause the outbreak
- The FDA has ended its on-site inspections and sample collection at iceberg lettuce growers and the processing facility in Mexico, though sample analysis is still pending
Why it matters: With nearly 20,000 cases since May 1 and two deaths in Michigan, the outbreak exposed a structural weakness: U.S. regulators were conducting fewer international inspections even as contaminated produce from central Mexico reached major restaurant chains, and the root cause of the sewage contamination that sickened 13,000 people remains unidentified.
