Cyclosporiasis outbreak: How to wash produce
More than 1,200 people have been sickened in Michigan, and officials say the parasite is hard to track as cases are investigated in 29 states.
According to The Associated Press, cyclosporiasis cases were confirmed or being investigated in 29 states as of Thursday. Cases are surging in Michigan, where more than 1,200 people have been sickened and 40 hospitalized.
Caused by the parasite Cyclospora, the illness typically spreads through fresh produce in hot weather rather than person-to-person. Experts note it is not considered a life-threatening disease.
Symptoms can appear two to 14 days after exposure, including frequent watery diarrhea and nausea. Public health agencies note one study found the parasite is "stickier" than other bacteria, limiting washing effectiveness.
To reduce risk, public health officials suggest avoiding prewashed bagged salad mixes. Consumers can instead choose thoroughly washed whole heads of lettuce or canned and frozen alternatives that remain nutrient-dense.
The outbreak is not considered a national health emergency. University professor Kali Kniel urged people not to panic, as registered dietitian Danielle Crumble Smith noted frozen vegetables remain a "great, very nutrient-dense option.
