Cyclospora Outbreak Surges to 45 States as Lettuce Recall Expands

A Cyclospora cayetanensis outbreak, known for causing explosive diarrhea, has surged to roughly 18,000 confirmed or probable cases across 45 states since May, with hundreds of hospitalizations and no deaths reported. Investigations point to shredded iceberg lettuce from central Mexico—used by Taco Bell—which led to recalls by Taylor Farms, though officials say other foods (and possibly multiple sources) may be involved. The outbreak’s rise is being tracked by the CDC and FDA, and scientists note the long incubation period (up to two weeks) and the difficulty of linking cases to a single food item. Prevention tips include cooking produce to at least 158°F, thorough washing, and avoiding recalled lettuce; health authorities urge continued vigilance as cases may continue to climb through late summer.
