The Food and Drug Administration (FDA) announced yesterday that it has narrowed down the source of the five-state Cyclospora outbreak to shredded iceberg lettuce served at Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio, and West Virginia. 

Michigan officials assessed 190 of the food exposures from Taco Bell and informed the Centers for Disease Control and Prevention (CDC) of their results. The vast majority of the people, 90%, admitted to eating iceberg lettuce from one of the restaurants. The CDC used data from 1,644 people who had cyclosporiasis from May 13, 2026, to July 13, 2026, and visited a Taco Bell to pinpoint the source of the outbreak. 

California-based Taylor Farms said today in a statement, “Taylor Farms de Mexico is voluntarily removing all iceberg lettuce sourced from central Mexico from the U.S. market. While the FDA traceback is indicating a specific independent farm that represents less than 1% of the U.S.’s iceberg lettuce supply as the potential source of the outbreak, we have removed all iceberg lettuce from the region indefinitely.”

Taylor Farms sells more than $7 billion in produce annually and makes more than 40% of salad kits available in the United States, according to the New York Times. 

In the past, Taylor Farms has been linked to other foodborne illness outbreaks, including when 631 people in 25 states became ill with cyclosporiasis after eating salad mix in 2013, according to NBC News. Two years ago, 104 people in 14 states contracted Escherichia coli after eating onions, which were connected to the company, on McDonald’s hamburgers.

The FDA discovered that the lettuce came from one supplier in Mexico and it is working with the company to determine if any contaminated lettuce remains on the market. The FDA also noted that Taco Bell agreed to pull lettuce from that supplier from its restaurants. 

While the FDA confirmed the shredded lettuce has been distributed in these five states, it is possible the lettuce was shipped to other locations, as well. Still, not every Taco Bell in these states received the tainted lettuce.
