What is Cyclosporiasis?

Cyclosporiasis is a parasitic infection caused by the Cyclospora cayetanensis parasite. It is typically spread through contaminated food or water. Symptoms include watery diarrhea, often described as explosive, along with loss of appetite, weight loss, stomach cramps, bloating, gas, nausea, and fatigue.

According to the CDC, symptoms usually appear about one week after exposure. The infection can last from a few days to several weeks if left untreated. Antibiotics are effective in treating cyclosporiasis.

Is Lettuce Safe to Eat in Iowa?

Only the recalled lettuce from Taylor Farms de Mexico is considered unsafe. Other brands of lettuce from other sources are safe to eat. The FDA recommends checking the list of recalled products, which includes Marketside brand lettuce sold at Walmart stores in Iowa.

For extra caution, consumers can stick to cooked fruits and vegetables until the investigation concludes. Taco Bell stopped using lettuce from Taylor Farms de Mexico on July 17, but Iowa locations were not specifically mentioned in the recall.

What Should Iowans Do?
