Trader Joe's Company of Monrovia, California is voluntarily expanding the recall of the Trader Joe’s Chocolate Chip Chewy Coated Granola Bars (SKU 82818) to include all code dates, manufactured by Bloomfield Bakery, a subsidiary of Ralcorp Holdings, Inc. because it has the potential to be contaminated with Salmonella, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Healthy persons infected with Salmonella often experience fever, diarrhea, nausea, vomiting and abdominal pain.
