A cyclosporiasis outbreak originating from contaminated Taylor Farms iceberg lettuce from Mexico has sickened over 20,000 people across 47 U.S. states and killed at least 2 people in Michigan as of early August 2026. The outbreak occurred after RFK Jr., as head of health initiatives, reportedly scaled back CDC disease tracking and food inspector staffing by roughly 3,000 employees since 2025, including removing cyclospora from mandatory reporting requirements. Health officials have linked the primary outbreak to lettuce distributed to Taco Bell locations and retail stores, though experts warn multiple sources may be involved and cases continue to climb.

“For someone who comes into an urgent care and cyclosporiasis is their only issue, it's relatively easy to treat. But for people who are struggling with other illnesses, it stands to reason that there are some patients that might not be able to withstand the dehydration that can come with severe cyclosporiasis.”
