A parasite capable of causing extreme diarrhea has been found in 18 states, with a particularly large outbreak in Michigan. Though the source of the infections has yet to be identified, experts recommend taking precautions with fresh produce and practicing good hygiene to reduce the risk of contracting the disease.
What’s cyclosporiasis? It’s a type of food poisoning caused by the parasite Cyclospora cayetanensis. It can cause “watery, and sometimes explosive, diarrhea and other stomach problems,” as well as a low-grade fever in some cases, said the Cleveland Clinic. Symptoms can start any time between two and 14 days after consuming contaminated food or water. The parasite is more common in tropical countries, but in mid-June, 145 cases were reported in the U.S.
There has been growing concern about cyclosporiasis because Michigan, which “typically identifies about 50 cases of cyclosporiasis in a year, has reported at least 170 cases” in under two weeks, said CNN. There’s “currently no evidence of a single, multistate Cyclospora outbreak linking all cases,” said the CDC. Instead, researchers are “working to identify various potential clusters and sources of illness in multiple states.”
Investigators have yet to pinpoint the cause of the current outbreak. But the most likely culprits are “cilantro, basil” and other plants that you “might put in a salad or use as a garnish,” as well as “strawberries, blueberries, melons” and other “things that grow in fields,” said David Freeman, a professor emeritus of infectious diseases at the University of Alabama at Birmingham, to CNN.
What can be done? Taking precautions is key to preventing illness. Cooked food is safer than fresh produce, as heat can kill the parasite. Washing produce can also help reduce the chance of ingesting the parasite. “Bleach doesn’t kill the parasite,” said CNN. “Handwashing with soap and water and a follow-up with an alcohol-based hand sanitizer are safer bets.”
If you contract cyclosporiasis, antibiotics can help clear the infection. If not treated, symptoms may “last for a month or longer,” said the Cleveland Clinic. “With proper diagnosis and treatment, most people feel better after a week or two,” but you may “still have occasional bouts of diarrhea for up to a month.”
