The foodborne gastrointestinal illness has emerged in 31 states, causing hospitalizations for 86 individuals, according to federal health officials.

A microscopic examination of a stool sample, stained with a modified acid-fast stain, showed four Cyclospora cayetanensis oocysts. This parasitic infection, known as cyclosporiasis, often leads to severe diarrhea.

Investigation in Michigan

Lettuce or salad greens may be linked to Michigan’s outbreak, as stated by Dr. Natasha Bagdasarian, the state’s chief medical executive. “Early information has shown lettuce as a common product that regularly comes up during the investigation,” said Dr. Bagdasarian.

The Michigan Department of Health and Human Services noted insufficient information to identify the specific produce, grower, or supplier. Other food items are still under consideration.

Michigan has reported 2,640 cases, the majority in the country. The Centers for Disease Control and Prevention (CDC) report approximately 3,000 cases nationwide.

Understanding Cyclosporiasis

This parasitic illness often presents flu-like symptoms such as severe fatigue, body aches, and progresses to watery diarrhea. Symptoms commonly include excess gas, stomach cramps, and nausea. Dehydration can pose a serious risk. Treatment involves fluids and antibiotics.

Michigan health officials advise against prepackaged salads. Consumers should purchase individual heads of lettuce, rinse them thoroughly, discard outer layers, and cook vegetables when possible.
