The CDC and FDA are now tracking two separate Cyclospora outbreaks that together have produced nearly 7,000 confirmed cases, with one clearly tied to Taylor Farms iceberg lettuce sold through restaurants and stores. The numbers have climbed quickly, and health officials continue to investigate how far the contamination reached. For gardeners who rely on fresh greens, the scale of the problem has prompted fresh questions about where their salad ingredients come from.
The Numbers Behind the Surge
One outbreak linked to Taylor Farms iceberg lettuce has produced 1,947 confirmed illnesses across nine states, with 98 hospitalizations and no reported deaths. Illness onsets in that cluster run through July 20. The second outbreak accounts for 4,173 laboratory-confirmed domestic cases, plus more than 7,400 additional suspected cases still under review, many reported from Michigan and Ohio. State totals already exceed the federal confirmed count in places. Michigan alone lists 8,176 cases with 160 hospitalizations so far, while Ohio reports more than 2,000. Officials note that not every state case may trace to the same source, and federal counting of new Cyclospora infections stopped after July 1, 2025.
Taylor Farms Recall and Distribution
Taylor Farms recalled iceberg lettuce from its central Mexico growing operations after traceback pointed to the product. The items reached restaurants, including Taco Bell, and retailers such as Walmart across more than two dozen states plus Mexico. Taco Bell stopped using the lettuce last week, while other customers have not issued public statements. FDA sampling initially appeared to detect Cyclospora in one Taylor Farms product, but the agency later called the result a false positive. Traceback and illness patterns still converge on the shredded iceberg from those Mexican fields. The recall now extends to Mexico as well, even after Mexican health officials reported negative tests from the plant.
What Remains Unclear
A specific source for the larger second outbreak has not been identified. Illness dates for both clusters now run from June 22 through July 20, a shift from earlier windows that removed roughly six weeks of cases from the official definition. The change reflects new data and the time needed to confirm whether individual illnesses belong to the outbreaks. Distribution may have reached additional states beyond those already named. Michigan and Ohio case counts continue to rise as more patient interviews are completed, leaving the final picture incomplete.
Symptoms and When to Seek Care
Cyclospora infection typically brings watery diarrhea, severe abdominal pain, nausea, vomiting, body aches, and fatigue. Symptoms appear two to 14 days after exposure and can last for weeks without treatment. Specific laboratory tests are required for diagnosis, and antibiotics are the standard therapy. The parasite spreads only through contaminated human waste on food or water. Unlike some bacterial pathogens, it does not come from animal feces. Most people recover, though hospitalization occurs in a notable share of confirmed cases. – Wash all produce thoroughly, even if pre-washed.
– Consider peeling or cooking items when possible.
– Track any symptoms after eating bagged or restaurant salads.
Growing Greens at Home
Many gardeners are turning to their own raised beds or containers for lettuce and other leafy greens. Home production removes the long supply chain that can introduce contamination during harvest, processing, or transport. Varieties suited to containers mature in weeks, and successive plantings keep fresh leaves available through much of the season. Soil, water, and handling remain under the grower’s direct control. Simple steps such as using clean containers, fresh potting mix, and regular harvesting reduce the chance of introducing the parasite. For those who value both flavor and peace of mind, a small salad garden offers a practical alternative while the current investigations continue.
