Federal officials hunted for the source of a 16-state salmonella outbreak linked to three types of raw tomatoes, while the list of supermarkets and restaurants yanking those varieties from shelves and dishes grew.
McDonald’s, Wal-Mart, Burger King, Kroger, Outback Steakhouse, Winn-Dixie and Taco Bell were among the companies that voluntarily withdrew red plum, red Roma or round red tomatoes unless they were grown in certain states and countries. In addition, officials at the Los Angeles Unified School District ù the nation’s second largest ù said Monday they have "indefinitely suspended" serving uncooked tomatoes. The FDA is investigating the source of the outbreak, agency spokeswoman Kimberly Rawlings said. "We are working hard and fast on this one and hope to have something as quickly as possible," Rawlings said Monday. Cherry tomatoes, grape tomatoes, tomatoes sold with the vine still attached and homegrown tomatoes are likely not the source of the outbreak, federal officials said.
