IOWA CITY, Iowa (AP) – Federal prosecutors have filed charges against an Iowa egg company and two executives blamed in a 2010 salmonella outbreak that sickened thousands of people. Disgraced egg industry titan Austin “Jack” DeCoster and his son Peter DeCoster were charged Wednesday with introducing adulterated food into interstate commerce, a misdemeanor. A charging document says the pair sold shell eggs that were poisonous for several months in 2010.

Their company, Quality Egg LLC, is charged with introducing misbranded food into interstate commerce, a felony. The document says Quality Egg sold products for years with labeling that “made the eggs appear to be not as old as they actually were.” The company is also charged with bribing a U.S. Department of Agriculture Inspector.

The outbreak led to an unprecedented recall of 550 million eggs.
