Houston, TX, July 20, 2026 —
Health officials have confirmed cases of Cyclospora infection in several Houston-area counties, prompting public awareness regarding a multi-state outbreak linked to shredded iceberg lettuce.
The intestinal illness has been identified in Fort Bend, Montgomery, Brazoria, and Galveston counties, according to local health authorities. The U.S. Food and Drug Administration (FDA) is actively investigating the outbreak, which has a wider reach across multiple states.
While an initial test on a specific sample of shredded lettuce returned a positive result for Cyclospora, it was later determined to be a false positive. Despite this, the FDA remains engaged in ensuring that any lettuce subject to recall is effectively removed from store shelves to prevent further spread of the parasite.
Cyclospora is a microscopic parasite that can cause gastrointestinal illness in humans. It is commonly found in soil and water and can contaminate fresh produce, particularly items like pre-cut lettuce and berries, which are challenging to wash thoroughly due to their texture and form.
Symptoms of Cyclospora infection typically include diarrhea, loss of appetite, frequent, urgent bowel movements, bloating, gas, stomach cramps, nausea, fatigue, and vomiting. Some individuals may experience these symptoms for weeks or even months if left untreated.
Health departments are advising residents to be aware of the situation and to seek medical attention if they develop symptoms consistent with Cyclospora infection. Practicing good hygiene, such as thorough handwashing before and after preparing food, is also recommended.
