Cyclospora Outbreak Map: Michigan Leads Cases; Taylor Farms Recalls Lettuce in 27 States
A widespread cyclosporiasis outbreak has infected at least 11,276 people across 46 U.S. states in 2026, according to Georgetown University's Health Security Operations Center. The parasitic infection causes prolonged watery diarrhea. Michigan and Ohio report the highest case counts, with the Midwest and mid-Atlantic regions most affected. Taylor Farms voluntarily recalled iceberg lettuce sourced from central Mexico, distributed from June 29 to July 16 in 27 states. The CDC has confirmed 1,645 domestic cases but notes over 5,100 more require analysis. Experts warn that multiple outbreaks may be concurrent, including one possibly linked to cilantro in New York. The parasite is resistant to disinfectants; cooking food to at least 158°F is recommended to kill it. The outbreak's end remains uncertain, as contaminated food must be removed from circulation or cooler temperatures must kill the parasites.
