No sicknesses have yet been connected to a Taylor Farms recall of several lots of tomatoes and salad kits for possible Salmonella contamination. The Tracy-based Taylor Farms, located in California’s San Joaquin County, is one of the nation’s biggest producers of salad makings. On Saturday, Sept. 13, Taylor Farms issued a recall for Expo Fresh Roma tomatoes it shipped to Costco locations in Los Angeles and Hawthorne, CA; Tacoma and Lynnwood, WA, and Las Vegas, NV. It involves only those tomatoes listed as packed on Sept. 5 or 6, 2014. Included in the recall, however, is Sicilian Vegetable Salad sold at deli counters at Safeway, Vons, and Pavilions grocery stores in California, Nevada, and Arizona, with use-by dates of Sept. 20 and 21, 2014. The kits are for the salads containing tomatoes. Taylor Farms said the possible Salmonella contamination was discovered during routine testing.
