IOWA CITY, Iowa (AP) — An Iowa company and two executives are expected to plead guilty to selling tainted eggs that were responsible for a 2010 salmonella outbreak that sickened thousands and led to an unprecedented recall of 550 million eggs, according to court documents filed Wednesday.

Disgraced egg industry titan Austin “Jack” DeCoster and son Peter DeCoster are charged with introducing adulterated food into interstate commerce, a misdemeanor that carries a maximum sentence of one year in jail. A charging document filed by federal prosecutors alleges that their company, Quality Egg LLC, sold eggs tainted with salmonella from early 2010 until the August 2010 recall and that the DeCosters were the responsible corporate officers.
