A parasitic infection called cyclosporiasis has sickened over 22,000 Americans since May 1, with confirmed cases in 47 states and probable cases still under investigation. The largest outbreak, affecting 15 states, traces to shredded iceberg lettuce supplied by Taylor Farms de Mexico to Taco Bell. Two deaths in Michigan and 517 hospitalizations have been reported, though the parasite is rarely fatal in the U.S.

The lettuce outbreak spans 15 states and keeps growing

As of August 6, the FDA confirmed 6,358 cyclosporiasis cases linked to Taylor Farms lettuce across 15 states: Michigan, Ohio, Missouri, Illinois, Indiana, Arkansas, Iowa, Nebraska, New Hampshire, and North Carolina. The outbreak began June 22, nearly a month before Taylor Farms issued a voluntary recall on July 17. The FDA expects cases to continue rising for up to six weeks after exposure because symptoms take time to develop and diagnose. Taco Bell removed all implicated lettuce from its supply chain.

Taylor Farms has a pattern of contamination incidents

Taylor Farms de Mexico is now linked to its second major cyclospora outbreak at the same facility, plus at least three other E. coli or cyclospora incidents over the past decade, according to a CNN investigation. The company has repeatedly downplayed responsibility and claimed its own testing found no parasites, though health experts note that contaminated produce is often consumed before testing occurs. FDA inspections have flagged sanitation problems at Taylor Farms facilities across the U.S., including pooling water testing positive for listeria in Colorado and improperly disinfected equipment in Tennessee.

Multiple outbreaks are under investigation beyond the lettuce cluster

The FDA is investigating six separate cyclospora outbreaks nationwide. Only one is definitively linked to Taylor Farms lettuce. The other five sources remain unknown, and food safety experts believe multiple sources are driving the surge. Cases could continue through the end of August. Public health officials are examining whether lettuce from other suppliers or entirely different produce items are involved in clusters outside the 15-state outbreak zone.

What cyclosporiasis does and how to treat it

Cyclosporiasis is a parasitic infection causing watery diarrhea, stomach cramps, nausea, fatigue, and weight loss. Symptoms typically begin 7 days after infection but can take up to 14 days to appear. Without treatment, symptoms last days to over a month and may relapse. The parasite spreads through food or water contaminated with feces. Antibiotics like Bactrim, Septra, or Cotrim treat the infection. Most people recover fully, though death is rare and typically occurs in people with serious underlying health conditions.

Final Thoughts

With over 22,000 cases across 47 states and the FDA investigating six separate outbreaks, consumers face ongoing risk beyond the recalled Taylor Farms lettuce. Health officials expect case numbers to rise through late August as diagnoses lag exposure by weeks.
