Federal health officials have conducted on-site inspections at a Taylor Farms processing facility in Mexico as part of their investigation into a nationwide cyclospora outbreak tied to contaminated lettuce. The U.S. Food and Drug Administration (FDA) confirmed this week that investigators traveled to the facility to review operations, weather records, satellite imagery, and testing materials. The inspections follow weeks of public health alerts linking the outbreak to shredded iceberg lettuce distributed by Taylor Farms de Mexico.
FDA confirms facility inspection as outbreak investigation intensifies
The FDA’s visit to the Taylor Farms facility in central Mexico marks a critical step in tracing the source of the cyclospora outbreak, which has sickened 9,481 people across 17 states since May 1, 2026, according to the latest data from the U.S. Centers for Disease Control and Prevention (CDC). The outbreak has resulted in 398 hospitalizations and two confirmed deaths, both reported in Michigan. The recalled lettuce, distributed to restaurants and food service providers, was traced back to Taylor Farms’ operations in Mexico and was subject to a voluntary recall on July 17, 2026. The FDA has stated that the recalled products’ best-by dates have passed, and they should no longer be available in stores or restaurants.
Outbreak spreads to 17 states as health officials urge caution
The number of affected states increased to 17 this week, with Maine and Massachusetts added to the list of locations reporting cases. The FDA’s Thursday update confirmed that the outbreak includes individuals who reported exposure to processed iceberg lettuce from Taylor Farms de Mexico, served or purchased at various locations. The CDC has recorded 13,895 laboratory-confirmed cyclospora cases nationwide in 2026, though the actual number is likely higher due to underreporting and limited testing for the parasite.
Cyclosporiasis, the illness caused by cyclospora, typically presents with symptoms such as watery diarrhea, loss of appetite, weight loss, cramping, bloating, increased gas, nausea, and fatigue. Symptoms can persist for weeks or months if untreated. The parasite is difficult to remove from produce, particularly delicate items like leafy greens or berries, and thrives in warm weather conditions.
FDA and CDC outline investigation priorities
The FDA, in coordination with the CDC and Mexican authorities, is conducting on-site inspections to reconstruct the conditions under which the contaminated lettuce was grown and processed. Investigators are reviewing weather records, satellite imagery, and testing materials, as well as examining the facility’s fields. The agency has faced criticism for the delay in visiting the Mexico site, with former health officials and food safety experts noting that inspectors had not visited the facility in the past seven years.
The FDA has initiated 21 foodborne illness outbreak investigations in 2026, a sharp increase compared to previous years. Cyclospora accounts for 13% of these investigations, trailing only salmonella, E. coli, and listeria. Health officials emphasize that the current outbreak is the largest recorded in the U.S., with cases reported in at least 47 states this year. The FDA and CDC continue to interview additional cases to determine the full scope of the outbreak and identify any additional contaminated sources.
Public health response and consumer guidance
The recalled lettuce products, which included iceberg lettuce sold under the Taylor Farms brand, were distributed to multiple states, including Alabama, Arkansas, Connecticut, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, and others. Consumers who may still have the recalled products are advised to discard them. Health officials recommend thorough washing of produce and seeking medical attention if symptoms of cyclosporiasis develop.
The FDA has not yet responded to requests for further comment outside of regular working hours. The agency continues to work with state and local partners to monitor the situation and provide updates as the investigation progresses.
