Midwest cyclosporiasis outbreak traced to shredded lettuce at Taco Bell
Health officials have linked a surge in cyclosporiasis cases across several Midwestern states to shredded iceberg lettuce served at Taco Bell restaurants, and have issued new safety recommendations for leafy greens.
Health authorities have identified shredded iceberg lettuce served at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio and West Virginia as the likely source of a Midwest cyclosporiasis outbreak. The finding was reported by an ABC News source familiar with the investigation.
The Michigan Department of Health and Human Services said confirmed cases in the state rose to 4,312, an increase of 1,003 since July 14, and noted 102 hospitalizations. While lettuce and salad greens are the focus of the investigation, officials said no specific grower or supplier has been identified and other foods cannot be ruled out.
The department issued updated guidance recommending consumers buy whole heads of lettuce rather than pre-washed, bagged varieties, discard the outer two to three layers of leaves, and wash the inner leaves under running water. Cooking greens to at least 158 °F (70 °C) is advised because the parasite is resistant to routine chemical disinfection.
Officials reminded the public that cooking, peeling, and thorough washing are the most effective ways to reduce the risk of cyclospora infection. People experiencing frequent watery diarrhea are urged to seek medical care and request testing for cyclospora, as standard stool tests may miss the parasite. Treatment typically involves antibiotics, rest and adequate hydration.
