(UPDATED COVERAGE, Sept. 16) Expo Fresh LLC, San Diego, and Taylor Farms are voluntarily recalling roma tomatoes because of potential salmonella contamination discovered during a routine sampling by government officials.

A recall notice dated Sept. 12 was posted on the Food and Drug Administration website late Sept. 15. Robert Schachtel, sales manager at Expo Fresh, said earlier that day the company had notified all of its customers who received roma tomatoes from the single implicated lot: No. 23914-214.

No illnesses have been reported in connection with the implicated roma tomatoes, Schachtel said. He referred additional questions to the company’s attorney, who was not immediately available.

Among those receiving the recalled roma tomatoes were Taylor Farms, Salinas, Calif., which issued a recall on Sept. 13 for the tomatoes and salads containing them.

Susan England, Taylor Farms quality assurance manager, said Sept. 16 that Taylor Farms “has corralled” almost all of the romas and related products it had shipped.

“We got the word late Thursday (Sept. 11) from Expo Fresh,” England said. “We immediately began notifying our customers.”

Taylor Farms distributed the tomatoes to Costco locations in Los Angeles and Hawthorne, Calif., Tacoma and Lynnwood, Washington, and Las Vegas, according to the recall notice on the FDA website. England said a Costco label example posted on the FDA website with the recall information is not the correct Costco label.

Taylor Farms also recalled Sicilian Vegetable Salad sold at deli counters at Safeway, Vons and Pavilions grocery stores in California, Nevada and Arizona. The salad kits for the deli salad contained the recalled roma tomatoes, according to news reports. The kits had use-by dates of Sept. 20 and 21.

Notices posted on the Web by Royal Food Service, Atlanta, and US Foods, Rosemont, Ill., reported the recalled roma tomatoes were shipped in 25-pound boxes.

Initial reports from US Foods and Royal Food Service also said some of the romas may have been shipped under the Lipman Produce label. However, Lipman chief operating officer Darren Micelle said Sept. 16 those reports were mistaken because the recall doesn't involve Lipman tomatoes.

Some media reports indicated only roma tomatoes packed on Sept. 5 and 6 are included in the recall, but the notice on the FDA site did not specify packing dates for the recalled products.
