Michigan Cyclospora Outbreak: Cases Surge 10x in Weeks

Michigan is currently experiencing a severe cyclosporiasis outbreak, with the number of reported cases surging dramatically. As of July 14, health officials have identified more than 3,309 cases statewide. This represents a tenfold increase in just under two weeks, with cases now exceeding 65 times Michigan's annual average.

Officials believe that lettuce and salad greens are the primary sources contributing to this widespread infection. The Michigan Department of Health and Human Services is actively investigating, with early data from over 1,000 interviewed cases suggesting a strong link to these produce items. While over 30 other states are also reporting cases, Michigan is currently leading in the number of infections.

To mitigate risk, health experts recommend thorough washing of produce, favoring whole heads of lettuce over bagged greens, and cooking vegetables when possible, as heat effectively kills the parasite. No deaths have been reported in connection with this outbreak, and the Centers for Disease Control and Prevention continues to monitor the situation nationally.
