- The CDC has confirmed 1,947 cases tied to people who ate at Taco Bell in the nine affected states, with at least 98 hospitalizations and no deaths reported.
- State health departments report a much higher total, with close to 12,000 confirmed or suspected cases nationwide. Michigan alone has counted nearly 8,000 cases.

What Cyclospora Is
Cyclospora is a tiny parasite that spreads through water contaminated with human feces. It clings to fresh produce like lettuce, herbs and fruit, which makes it hard to wash off completely. Once someone eats contaminated food, the parasite can cause an illness called cyclosporiasis, which brings watery diarrhea, stomach cramps, nausea and fatigue that can last for weeks if untreated.
Why This Outbreak Is So Large
Health officials say this year’s outbreak season, which typically runs from May through August, started unusually early and has produced far more cases than the same period last year. The CDC has sent staff to Ohio, one of the hardest-hit states, to help local investigators trace how the contamination spread. Because Cyclospora infections can take up to six weeks to confirm, officials expect the case count to keep rising even as new lettuce is pulled from stores.
How to Protect Yourself
Check any iceberg lettuce in your home against the Taylor Farms recall list before eating it, including lettuce served at restaurants and fast food chains. If you’ve eaten iceberg lettuce recently and have persistent diarrhea lasting more than a few days, contact a doctor. Cyclosporiasis is typically treated with a course of antibiotics, and most people recover fully once treated.
