Cases of cyclosporiasis have now spread to 37 counties in Florida, with reported illnesses spiking by nearly 100 in just one week this month.

U.S. health officials are investigating a new outbreak involving the diarrhea-causing parasite cyclospora.

The Food and Drug Administration has opened investigations into three new foodborne illness outbreaks, with federal health officials working to identify the source of each.

Federal health officials have remained focused on lettuce from Taylor Farms as the source of a multistate outbreak despite inaccurate test results reported over the weekend.

Taylor Farms has expanded a voluntary recall of its iceberg lettuce products sourced from central Mexico because of a potential link to the multistate cyclospora outbreak that has sickened people across the U.S. The California-based company said products with the potential to be contaminated with the diarrhea-causing parasite were shipped to 27 states including Texas, Florida, Pennsylvania and Illinois.

Federal health officials have identified lettuce from Mexico served by Taco Bell locations across five U.S. states as a source of the widespread outbreak of diarrhea-causing parasite cyclospora.

A parasite that causes extreme diarrhea, seen in recent outbreaks across the country, has been documented in over 25 counties in Florida -- and cases nearly doubled in one week, according to state data.

Infections from the diarrhea-causing parasite cyclospora are surging, with 2026 already the nation's worst year for reported cases.

JACKSONVILLE, Fla. - A Georgia man is suing Coopers Hawk Winery & Restaurant, a Mexico-based logistics company and a Jacksonville produce wholesaler for more than $15,000 in damages, saying he got sick for several weeks after dining at the restaurant. Defendants named in the latest lawsuit include Siga Logistics, the Morelos, Mexico, company that produced the basil; The Garden Produce, the wholesaler that distributed it; and Coopers Hawk, where the basil was eventually served. A manager at Cooper's Hawk referred a reporter to a previous statement provided by the restaurant. The lawsuit follows a previous suit, filed July 12 by Lekeysha Bentley, which alleged Bentley got sick a few days after eating at Cooper's Hawk. Most of those cases appear to have happened in Jacksonville with a local attorney saying 100 customers claim to have gotten sick after dining at Coopers Hawk.
