America’s biggest food distributor just cut ties with lettuce grown in central Mexico, after a parasite outbreak tied to that produce sickened thousands and is linked to two deaths.
Story Snapshot
- Sysco, the nation’s largest food distributor, stopped buying iceberg lettuce from Mexico and from supplier Taylor Farms, its chief executive confirmed.
- The Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC) link the outbreak to iceberg lettuce sourced from central Mexico.
- Taylor Farms de Mexico recalled all iceberg lettuce from that region on July 17, affecting nearly 30 states.
- The outbreak has grown into one of the largest cyclosporiasis events on record, with more than 4,000 lab-confirmed cases.
A Major Distributor Pulls Back From Mexican Lettuce
Sysco chief executive Kevin Hourican said the company has stopped buying iceberg lettuce from Taylor Farms and from Mexico entirely. Sysco supplies restaurants, schools, and hospitals nationwide, so the decision ripples far beyond grocery store shelves.
Hourican tied the move directly to the federal investigation into cyclosporiasis, a parasitic illness that causes days of watery diarrhea, cramping, and fatigue in infected people.

The FDA and CDC say their investigation points to iceberg lettuce sourced from central Mexico and recalled by Taylor Farms de Mexico. Taylor Farms voluntarily pulled all iceberg lettuce from that region off the U.S. market on July 17, a recall that eventually covered products in 27 states with best-by dates stretching into early August.
How the Outbreak Grew and Spread Through Restaurants
The first public thread connected shredded iceberg lettuce to Taco Bell locations in several states before investigators widened the scope. Case counts climbed fast.
The CDC reported more than 4,100 domestically acquired, lab-confirmed cyclosporiasis cases since May 1, making this one of the largest such outbreaks the country has ever tracked. Health officials eventually linked cases across nine states to the same supply chain.
Two deaths have been reported in connection with the outbreak, according to coverage of the crisis, though officials continue investigating the full scope of illnesses and any additional contributing factors.
Taco Bell, Walmart, and other retailers pulled affected lettuce from their supply chains once the FDA identified Taylor Farms de Mexico as the common thread running through multiple state health department reports.
A Disputed Test Result Complicates the Timeline
Not every detail in this outbreak has been simple. On July 20, the FDA acknowledged that one positive lab sample from Taylor Farms lettuce was actually a false positive, walking back a specific finding while still standing by the broader recall.
The agency was clear that this correction did not change its underlying conclusion that shredded iceberg lettuce from central Mexico remained the likely source of contamination.
Some reporting has noted that, as of certain update dates, there were no confirmed positive product samples tied to the outbreak, even as the recall stayed in place. That gap reflects a real challenge in cyclosporiasis investigations.
The parasite is notoriously hard to trace because it is not routinely tested for the way bacterial contaminants are, and symptoms can take more than a week to appear after exposure.
That delay makes pinpointing an exact contaminated batch difficult even when the broader traceback data all point the same direction. Reuters reported that authorities linked the outbreak to Taylor Farms-sourced lettuce while also noting investigators were still looking at other potential sources, a normal part of narrowing down a sprawling, multistate food safety case.
Why the Distinction Still Matters for Families and Businesses
None of this walks back the core finding driving Sysco’s decision. Federal health officials still say the traceback evidence converges on iceberg lettuce grown in central Mexico and processed by Taylor Farms.
A single retracted lab result does not erase the pattern of illness reports, restaurant exposure clusters, and recall data that led both regulators and a major distributor to act with real urgency.
For everyday families, the practical takeaway is straightforward. Recalled lettuce should not be purchased or served, and restaurants sourcing from affected supply chains have already made changes.
Businesses like Sysco choosing caution over profit, even before every lab test is finalized, reflects the kind of responsibility consumers should expect from companies handling the nation’s food supply.

Federal investigators continue refining the picture, and updates from the FDA and CDC are expected as case counts are finalized. Consumers should watch for further recall notices and check with retailers about affected lot numbers before assuming any iceberg lettuce on shelves today is part of the recalled product.
