Taylor Farms is issuing a recall of some lots of tomatoes and salad kits that include them because they may be contaminated with Salmonella.

Taylor Farms of Tracy issued the voluntary recall Saturday night for Expo Fresh Roma tomatoes shipped to Costco locations in Los Angeles and Hawthorne in California, Tacoma and Lynwood in Washington, and Las Vegas in Nevada. Only tomatoes listed as packed on September 5 or September 6 are affected.

The recall also includes Sicilian Vegetable Salad served at deli counters at Safeway, Vons and Pavilions grocery stores in California, Nevada and Arizona with use-by dates of September 20 and September 21. The kits for the salad contained the tomatoes.

The company says the Salmonella was found in routine testing. No illnesses have yet been reported.
