8/19/2026, 10:10:09 PM
Core Event: Nationwide Rise in Cyclosporiasis Cases
The CDC reports 15,716 laboratory-confirmed cases, 828 hospitalizations and two deaths across 47 states, D.C., and Puerto Rico. The latest weekly update added 1,821 cases.
Background & Context: Lettuce Recall and Earlier Outbreak
The largest cluster is tied to iceberg lettuce grown in central Mexico and supplied by Taylor Farms de Mexico. The product reached at least 31 states, including Taco Bell and Walmart Marketside lettuce. A voluntary recall was issued on July 17. Federal investigators have linked 9,481 illnesses, 398 hospitalizations and two deaths (both in Michigan) to the recalled lettuce.
Data & Statistics
- CDC total: 15,716 cases; 828 hospitalizations; 2 deaths.
- State reports: Michigan – 13,909 cases, 2 deaths; Ohio – 5,526 cases; Florida – 407 cases (May 1–early August).
- Outbreak-specific: 9,481 illnesses, 398 hospitalizations, 2 deaths (Michigan).
- Hospitalization trends: Michigan reports 314 hospitalizations, up from 279 the previous week; Ohio and other states show similar increases.
Official Statements & Responses
- The CDC notes cyclosporiasis symptoms include watery diarrhea, nausea, abdominal cramps, fever and fatigue, with onset 2 days to 2 weeks after exposure.
- Routine stool tests may miss Cyclospora; the CDC advises specific testing for persistent gastrointestinal symptoms.
- The FDA inspected Taylor Farms de Mexico with Mexican authorities, reinforcing the recall and confirming expired best-by dates.
- Michigan’s health department dropped its earlier recommendation to buy whole heads of lettuce on July 1, now urging standard food-safety practices.
- Florida’s health department, which averages 246 annual cases (2015-2025), notes recent counts have exceeded 500 and will release an update later in August.
Conflicting Reports & Gaps
- CDC vs. state counts: CDC’s 15,716 confirmed cases exclude probable cases; Michigan and Ohio report higher totals that combine confirmed and probable infections.
- CDC vs. CBS12: CBS12 cites 13,895 laboratory-confirmed cases through early August, while the CDC’s later update lists 15,716, reflecting different cut-offs.
- Hospitalization figures: CDC reports 828 nationwide; CBS12 reports 740; Michigan alone reports 314, showing variation in data collection.
Impact and Public Health Guidance
The outbreak highlights fresh-produce supply-chain vulnerability. Hospitalizations and deaths are concentrated among older adults, pregnant individuals and immunocompromised patients. Officials advise consumers to avoid the recalled lettuce, wash fresh greens thoroughly, and seek medical care for prolonged diarrhea.
What’s Next
Federal agencies will keep weekly CDC updates. State health departments will continue bulletins and adjust food-safety recommendations as case numbers change. The FDA’s investigation of the lettuce supply chain remains ongoing, with further sampling planned with Mexican regulators.
