The cyclosporiasis outbreak has expanded to nine states as the CDC investigates over 7,400 suspected cases, making it the largest on record. This parasitic infection, linked to shredded iceberg lettuce from Taco Bell, has sickened thousands across the Midwest and beyond.
Understanding Cyclosporiasis and Its Symptoms
Cyclosporiasis is caused by the Cyclospora cayetanensis parasite, which contaminates raw produce through fecal matter. Symptoms include explosive, watery diarrhea that can relapse for weeks, along with nausea, cramps, and fatigue. The illness typically occurs in summer months, and the CDC has confirmed 4,173 laboratory-tested cases so far.
How the Outbreak Spread
The investigation began in five states—Indiana, Kentucky, Michigan, Ohio, and West Virginia—where Taco Bell restaurants served contaminated iceberg lettuce. The FDA later added Illinois, Oklahoma, Pennsylvania, and Kansas to the probe, bringing the total to nine. The supplier, Taylor Farms de Mexico, issued a voluntary recall.

| Indiana | 52 | Taco Bell lettuce |
| Kentucky | 41 | Taco Bell lettuce |
