US Confirms Over 4,100 Cyclosporiasis Cases Linked to Mexican Lettuce

The United States has confirmed more than 4,100 cases of cyclosporiasis, an intestinal parasitic infection causing diarrhea, linked to contaminated lettuce originating from Mexico. The Centers for Disease Control and Prevention (CDC) reported over 2,500 new infections in the past week alone, bringing the total number of confirmed cases to 4,173 across 41 states since May 1. Health Secretary Robert F. Kennedy Jr. declared the outbreak "under control," noting that the source has been identified and product recalls have been initiated. The FDA had previously retracted a positive test for the parasite in iceberg lettuce from Taylor Farms' Mexican subsidiary, but a large-scale recall of affected products, including 35 items distributed across 27 states, remains in effect. Consumers are urged to discard any recalled products. The current outbreak is significantly larger than last year's, with confirmed or suspected cases reportedly 27 times higher than in the same period in 2025.
