The US cyclosporiasis outbreak has expanded to nine states, with the CDC investigating over 11,500 suspected cases. This unprecedented outbreak, linked to shredded iceberg lettuce from Taco Bell, underscores the importance of food safety and awareness.
What Is Cyclosporiasis?
Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. It spreads when people consume food or water contaminated with feces containing the parasite. Symptoms include explosive, watery, and relapsing diarrhea that can last for weeks if untreated.
Outbreak Details and Expansion
The CDC reports 4,173 laboratory-confirmed domestic cases and an additional 7,400 under investigation. Initially concentrated in Indiana, Kentucky, Michigan, Ohio, and West Virginia, the investigation now includes Illinois, Oklahoma, Pennsylvania, and Kansas. The contaminated lettuce was supplied by Taylor Farms de Mexico, which issued a voluntary recall. The FDA is also probing 72 separate cases not yet linked to a specific product.

| Illness | Source | Typical Duration | Key Symptoms |
|---|---|---|---|
| Cyclosporiasis | Contaminated produce (e.g., lettuce, berries) | Weeks to months if untreated | Watery diarrhea, fatigue, weight loss |
| Salmonellosis | Undercooked poultry, eggs, produce | 4-7 days | Diarrhea, fever, abdominal cramps |
| E. coli O157:H7 | Undercooked beef, contaminated veggies | 5-10 days | Bloody diarrhea, severe cramps, vomiting |
Key Takeaways
- Cyclosporiasis is a parasitic infection often linked to raw produce.
- The current outbreak is the largest on record, with cases in nine U.S. states.
