A significant listeria outbreak has been reported in California and Nevada, resulting in hospitalizations of at least 10 individuals. The outbreak is linked to ready-to-eat foods, particularly sandwiches and snacks sold in several states including Arizona, California, Nevada, and Washington. In response to the health risks, Fresh & Ready Foods has voluntarily recalled their ready-to-eat sandwiches and snack items due to possible contamination with Listeria monocytogenes. Authorities are urging consumers to be cautious and monitor any symptoms related to listeria infection.
