Federal health officials declared an end to the largest cyclospora food poisoning outbreak in U.S. history, which sickened 12,883 people across 21 states and was linked to contaminated lettuce from Taylor Farms. The FDA says its investigation remains ongoing despite the outbreak being declared over.
Michigan health officials cleared shoppers to resume normal lettuce consumption after cyclospora parasite infections linked to tainted lettuce began declining. The outbreak had prompted widespread warnings and consumer anxiety about salad greens.
A major cyclosporiasis outbreak has infected over 11,000 Americans, with Michigan reporting more than 10,000 cases. FDA officials are defending the safety of the U.S. food supply while experts point to vulnerabilities in the food safety tracking system.
The U.S. Food and Drug Administration announced it is investigating a new outbreak of cyclosporiasis involving 72 reported cases. The source of the parasitic infection, which causes severe gastrointestinal illness, has not yet been identified and is separate from previously recalled lettuce.
The FDA apologized and confirmed that laboratory results showing cyclospora parasite in Taylor Farms lettuce samples were false positives after re-testing, as investigation into the outbreak affecting over 5,000 cases continues.
California-based produce supplier Taylor Farms is voluntarily recalling all iceberg lettuce sourced from central Mexico following a cyclosporiasis outbreak that has sickened thousands of people, primarily in Michigan and nearby states.

Michigan health officials reported 4,312 cases of cyclosporiasis as of Thursday, marking an increase of 550 cases in one day. Investigators are still working to identify the source of the unusually large outbreak of the intestinal illness.
Michigan health officials reported 3,309 cases of cyclosporiasis on Tuesday, an increase of 669 cases since Monday, with the parasitic illness outbreak resulting in 44 hospitalizations. The diarrhea-causing infection is part of a broader outbreak affecting 31 states.
