The Department of Justice has started an investigation into Blue Bell after its ice cream was linked to a deadly Listeria outbreak earlier this year that killed three people, according to CBS News.
An FDA investigation found Listeria in all three of Blue Bell's production plants located in Alabama, Oklahoma and Texas. Records indicated that the company knew one plant was contaminated at least as early as 2013.
The FDA investigation uncovered other troubling problems, including condensation dripping directly into ice cream and unsanitary equipment. Last April, Blue Bell shut down all three production facilities, and all ice cream was recalled.
