Parasitic outbreak of cyclosporiasis linked in Michigan to lettuce

Key Points:

• Michigan is experiencing a cyclosporiasis outbreak that has sickened over 2,600 residents, believed to be linked to infected lettuce or salad greens, though other food items have not been ruled out.
• Health officials have not yet identified a specific type of produce, grower, or supplier as the definitive source, and investigations are ongoing with more than 1,000 affected individuals interviewed.
• Cyclospora, the parasite causing the illness, leads to symptoms like watery diarrhea, nausea, and stomach cramps, and is contracted through contaminated food or water.
• The Michigan Department of Health and Human Services recommends consumers buy whole heads of lettuce instead of pre-washed or bagged varieties, discard outer leaves, and thoroughly wash inner leaves to reduce risk.
• The outbreak is part of a larger national issue, with 843 cases reported across 31 states since May, and officials caution that the investigation will take time due to the outbreak's scale.
