BRENHAM, Texas – The Center for Disease Control and Prevention has released its final report on the Blue Bell Listeria outbreak.
It found 10 people were infected with the bacteria in Arizona, Kansas, Oklahoma, and Texas from January 2010 to January 2015.
All 10 people were hospitalized, and three of them in Kansas died.
New documents released by the FDA on Wednesday indicated Blue Bell may have found the source of Listeria contamination at its Oklahoma plant — ingredients that were stored in an unsanitary room.
But the source of bacteria at its other two plants remained a mystery.
In April, Blue Bell recalled all of its products.
The CDC warns people could still get infected because the recalled products may still be in the freezers of consumers.
Blue Bell has said it is completely reassessing and revamping its plant operations to make sure its products are safe in the future.
The outbreak has seriously hurt the company, which temporarily closed factories in Oklahoma and Texas and laid off more than 1,400 workers in May.
Blue Bell did not say when they plan to resume production and be available in stores.
