Aug. 14 (UPI) -- U.S. health officials said they have begun inspections at the Mexican processing plant of the U.S. food distributor Taylor Farms as they deal with a continuing cyclosporiasis outbreak that has spread across 17 states.

The Food and Drug Administration and the Centers for Disease Control and Prevention announced Thursday they have "initiated an onsite inspection and sampling" at Taylor Farms de Mexico's facility in Guanajuato, Mexico, located about 185 miles northwest of Mexico City.

Taylor Farms, based in Salinas, Calif., voluntarily recalled all iceberg lettuce from that area on July 17, including shredded lettuce used in Taco Bell products and in salad kits sold in some grocery stores.

Taco Bell also said it was removing shredded lettuce supplied by Taylor Farms in affected states.
