WASHINGTON — Federal health agencies have traced a massive multistate outbreak of Cyclospora infections to shredded iceberg lettuce, prompting a major international supplier to pull its products from the U.S. market.
There is exactly one confirmed case of cyclosporiasis reported in Lawrence County, two in Jackson County, six in Monroe County, two cases in Orange County, and three in Washington County, according to state health data as of Friday, July 17.
Taylor Farms de Mexico announced a voluntary withdrawal of all iceberg lettuce sourced from central Mexico on July 17, 2026. The move follows an intensive traceback investigation by the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC), which converged on the company as the single supplier of contaminated lettuce linked to widespread illnesses.
The outbreak has sickened at least 1,644 people across five states—Indiana, Kentucky, Michigan, Ohio, and West Virginia—resulting in 94 hospitalizations. Illness onset dates range from May 13 to July 13, 2026. Epidemiological data highlighted a strong connection to Taco Bell locations in those states, where 90% of interviewed patients reported consuming meals containing iceberg lettuce.
Major Retail Chains and Restaurants Affected
In tandem with the market withdrawal, Taylor Fresh Foods initiated a sweeping recall of retail and food service products distributed between June 29 and July 16, 2026.
The recall heavily impacts Walmart stores across 15 states, where the following Marketside-brand items are being pulled from shelves:
- Marketside Iceberg Salad (12-oz and 24-oz): Best if Used By dates from 7/18/2026 to 8/3/2026.
- Marketside Shredded Lettuce (8-oz and 16-oz): Best if Used By dates from 7/18/2026 to 8/3/2026.
Taco Bell announced that it has entirely ceased using lettuce from Taylor Farms de Mexico as of July 17. The fast-food chain’s impacted locations are concentrated in Indiana, Kentucky, Michigan, Ohio, and West Virginia. However, health officials warn that broader distribution channels could expand the advisory’s scope.
The scope of known product distribution from this recall spans 28 states, including large portions of the Midwest, South, and East Coast.
Surveillance Catches Contaminated Sample at Border
Underscoring the ongoing risk, the FDA revealed that a sample of shredded iceberg lettuce from Taylor Farms de Mexico collected during targeted import surveillance at the border tested positive for Cyclospora.
While Taylor Farms confirmed that this specific positive lot was detained at the border and did not enter commercial streams, the company is actively auditing its records to ensure no portion of the implicated lot reached consumer homes. Border screening has been heavily increased for all fresh produce arriving from the central Mexico region.
Understanding Cyclosporiasis Symptoms
Cyclospora is a microscopic parasite that causes cyclosporiasis, an intestinal illness. The infection is uniquely frustrating for patients because its symptoms can fluctuate significantly.
Key Signs of Infection: Most infected individuals experience severe, watery diarrhea with frequent bowel movements. Other common symptoms include loss of appetite, significant weight loss, stomach cramps, bloating, increased gas, nausea, and fatigue. Some individuals remain entirely asymptomatic.
If left untreated, cyclosporiasis can lead to severe dehydration and long-term complications lasting from a few days to more than a month. The illness is notorious for a relapse pattern, where symptoms appear to clear up only to return weeks later. Immunocompromised individuals face a much higher risk of prolonged, severe illness requiring hospitalization.
Action Steps for Consumers and Retailers
The FDA has issued strict directives to control the spread of the parasite:
- Discard Immediately: Consumers, restaurants, and retailers holding any recalled Taylor Fresh Foods or Marketside iceberg products should throw them away immediately. Retailers are offering full refunds at the point of purchase.
- Verify Restaurant Sources: Diners are advised not to eat iceberg lettuce at Taco Bell or other restaurants in the affected regions unless the establishment can explicitly confirm the lettuce did not originate from Taylor Farms de Mexico.
- Sanitize Surfaces: Any refrigerator drawers, countertops, or containers that came into contact with the recalled lettuce must be thoroughly washed and sanitized to eliminate the risk of cross-contamination.
- Seek Medical Care: Anyone exhibiting symptoms who consumed shredded iceberg lettuce within the past two weeks should contact their healthcare provider immediately.
Federal authorities note that case counts are expected to rise as state laboratories process outstanding patient samples.
