'Explosive Diarrhea' Parasite Cyclospora Sickens Thousands in US; Taco Bell Investigated
Over 5,000 people in the US have been infected with Cyclospora, a parasite causing severe diarrhea. The outbreak has been linked to salad greens, and Taco Bell has voluntarily recalled some produce. Federal budget cuts hinder investigation efforts.
Widespread Cyclospora Outbreak
The United States is experiencing a major outbreak of cyclosporiasis, caused by the microscopic parasite Cyclospora cayetanensis. Symptoms include watery, explosive diarrhea, nausea, cramping, and fatigue. The CDC has confirmed 1,645 cases since May 1, with over 5,000 total infections reported, including 141 hospitalizations. No deaths have occurred.
Taco Bell and Produce Under Scrutiny
Michigan has the highest number of cases at 2,640. State health officials point to lettuce and other salad greens as potential sources. According to The Washington Post, federal and state investigators are looking into Taco Bell after the chain voluntarily recalled lettuce, cilantro, onion, pico de gallo, and guacamole at certain locations.
Investigation Challenges Amid Budget Cuts
The parasite has a long incubation period (up to two weeks) and is not detectable by standard diarrheal tests. Complicating matters, the FDA lost over 240 consumer safety specialists last year due to federal cuts, and the CDC scaled back its FoodNet surveillance program. Experts note that tracking Cyclospora is notoriously difficult due to the short shelf life of fresh produce and uneven contamination distribution.
Expert Advice
While the CDC and FDA do not currently recommend avoiding specific foods, experts advise thorough washing of produce. In high-case areas, immunocompromised individuals should consider avoiding raw greens. The investigation is ongoing, with officials warning that previous outbreaks have been traced to leafy greens, raspberries, and herbs.
