FDA issues warning to Kellogg over listeria bacteria at Eggo plant

The U.S. Food and Drug Administration sent a warning letter to the Kellogg Co. after government testing showed the company's Georgia facility that manufactures Eggo waffles was contaminated with the listeria bacteria and had numerous sanitation violations.

The letter, just made public, is a potential public relations nightmare as the company refills freezer cases short on Eggo products after the discovery of listeria in buttermilk waffles at the plant last summer and subsequent flooding. The contamination and flooding forced the company to pull products from the market and then halted production.
