Fresh-cut roma tomatoes grown in Mexico and distributed to Costco by Boskovich Farms Inc. may have been contaminated with salmonella and are part of a voluntary recall Expo Fresh LLC initiated in September.

Coral Beach of The Packer reports Boskovich was not named in the Sept. 12 recall notice on the Food and Drug Administration’s website. However, the Oxnard, Calif., company and its diced roma tomatoes were included in the agency’s Oct. 7 weekly enforcement report.

No illnesses have been reported in connection to the tomatoes, according to the FDA. The recall was initiated after a routine sampling by government officials returned positive results for salmonella.
