Cyclospora outbreaks grow in the Midwest, CDC investigates
7 reported1 unconfirmed
The Centers for Disease Control and Prevention report multiple states have seen an increase in cases of cyclosporiasis, an intestinal illness caused by the Cyclospora parasite. The outbreak is hitting Ohio and Michigan the hardest, with Michigan reporting more than 1,500 cases, compared to its typical annual total of about 50. Nationwide, cases have been reported in 31 states, and 86 people have been hospitalized. No deaths have been reported. The CDC has initiated a traceback investigation, but the source of the outbreak is not yet known. Prior outbreaks have been linked to fresh produce such as raspberries, leafy greens, and herbs. Food safety experts say heating food to 158 degrees Fahrenheit is the most effective way to kill the parasite, though rinsing produce under warm water may also help.
