Cyclosporiasis outbreaks: What to know about the foodborne illness and symptoms

NBC NewsIndependentCenterFactual 88Objective 803 days ago

Health officials in Michigan have identified lettuce or salad greens as potential sources of a cyclosporiasis outbreak, a parasitic infection causing severe diarrhea and other gastrointestinal symptoms. While investigations have pointed to lettuce as a commonly implicated product, the specific type of produce, grower, or supplier remains unidentified. The outbreak has affected over 2,600 individuals in Michigan alone, with nearly 3,000 total cases reported across 31 U.S. states. According to the CDC, 86 people have been hospitalized due to the illness, though the true number may be higher as symptoms can take up to a week to manifest. Health authorities recommend avoiding pre-packaged salads, washing lettuce thoroughly, discarding outer leaves, and cooking vegetables when possible to reduce risk.

A cyclosporiasis outbreak caused by the parasite Cyclospora has affected nearly 7,000 people across 34 U.S. states this summer. Michigan health officials identified lettuce and salad greens as a potential source, advising consumers to buy whole heads and discard outer leaves. However, no specific grower or supplier has been confirmed, and the CDC remains uncertain whether this is a single outbreak or multiple unrelated clusters. The lack of clear answers has led to widespread misinformation online, including false remedies like vinegar rinses and warnings against eating berries. As the situation unfolds, some businesses, like Taco Bell, have removed lettuce from menus without official recalls, raising concerns about the reliability of information. The article highlights systemic issues in food safety, including reduced surveillance and traceability efforts, which hinder accurate identification of contamination sources.
