A Cyclospora outbreak linked to recalled iceberg lettuce has affected 1,947 individuals across nine states in the U.S. This outbreak, sourced from central Mexico, is among the largest in U.S. history, though it has yet to exceed the 2019 record.
Health officials expect the number of cases to rise due to delays in infection confirmation. Agencies like the CDC and FDA are investigating the outbreak, which traces back to iceberg lettuce from Taylor Farms de Mexico. A voluntary recall was initiated on July 17, advising consumers to discard or return the potentially contaminated lettuce.
Understanding Cyclospora
Cyclospora cayetanensis is a microscopic parasite causing cyclosporiasis, affecting the small intestine. Infection occurs by ingesting contaminated food or water, often fresh produce such as leafy greens. Symptoms, appearing about a week post-exposure, include watery diarrhea, appetite loss, weight loss, stomach cramps, and fatigue. Left untreated, symptoms may persist or recur over weeks or months. Healthy individuals typically recover with antibiotics.
Historical Outbreaks
Cyclospora was identified as a North American foodborne illness in the mid-1990s due to a Guatemalan raspberry-linked outbreak. It led to a CDC national notification designation. Further notable outbreaks in 2013 were tied to salad mixes and cilantro from Mexico.
The largest outbreaks occurred later: salad mix at McDonald’s and fresh produce in 2018 with 2,299 cases, and the 2019 basil outbreak from Mexico with 2,408 cases.
Future Case Increases
The CDC warns of future confirmed cases due to delays in illness attribution, despite recall actions. The outbreak investigations include unrelated national cases, and some recover without testing.
The FDA traceback points to Taylor Farms’ central Mexico iceberg lettuce suppliers. Consumers should continue avoiding recalled products.
Taylor Farms’ Response
Taylor Farms prioritizes food safety, stating none of their products tested positive for Cyclospora. The company removed implicated products, issued a vast recall, and suspended sourcing from the affected region. Independent experts are reviewing their safety practices.
By July 24, 2026, no product tests confirmed Cyclospora presence according to the FDA. Taylor Farms emphasizes their commitment to food safety transparency.
