July 17 (UPI) -- Taylor Farms announced Friday it is removing all iceberg lettuce sourced from central Mexico from the U.S. market, after federal officials said they traced the cyclosporiasis outbreak that's caused illness in thousands of people to lettuce supplied to Taco Bell restaurants in five states.

The U.S. Centers for Disease Control and Prevention and the Food and Drug Administration said their investigators found the shredded iceberg lettuce came from Taylor Farms, a supplier that also sells salad kits in grocery stores.

In a statement, the company said it is voluntarily removing all of its Mexico-sourced iceberg lettuce, adding the outbreak is not associated with any of its salad kits.

"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," the company statement said.
