On Friday FDA released another update to its investigation of the Salmonella Infantis outbreak linked to Del Monte vegetable trays. The agency has been unable to find a single source or contamination point for the outbreak, but it also states that it’s not likely that these trays are either on store shelves or in consumers’ homes. The illness cases have been isolated to five people in Minnesota and Wisconsin, with the last illness onset reported on May 15. No hospitalizations or deaths have been reported.
