The U.S. Department of Justice is investigating an outbreak of listeria involving Blue Bell ice cream. The probe has implications here in Alabama. Blue Bell Ice Cream’s plant in Sylacauga was among those shut down due to the presence of listeria. The U.S. Justice Department wants to know when company officials knew the potentially dangerous bacterial outbreak was present and how Blue Bell responded. Records indicated that the company knew one plant was contaminated at least as early as 2013. The ice cream maker shut down all of its factories in April. The Food and Drug Administration later confirmed listeria in all of Blue Bell’s plants, including the one in Alabama. The DOJ is cracking down on companies that produce dangerous food products.
