Overview
- Federal updates released late this week show about 6,700 laboratory-confirmed cyclosporiasis cases and more than 11,500 additional suspected reports that are under review, totaling over 18,000 illness reports.
- Michigan has reported the largest state total with more than 10,000 confirmed cases, making it the hardest-hit area in the multistate event.
- Investigators have linked a large multistate cluster to shredded iceberg lettuce supplied by Taylor Farms and served at some Taco Bell locations, prompting voluntary recalls and product removals.
- Health officials say the parasite is hard to confirm because it cannot be easily cultured, yields limited DNA for genomic fingerprinting, and testing backlogs slow lab confirmation, and there have been hundreds of hospitalizations but no deaths.
- Officials are pursuing multiple parallel investigations into other possible produce sources, public guidance urges safer handling and cooking of greens, and the outbreak has already cut lettuce sales and triggered legal action and supply‑chain changes.
