Blue Bell ice-cream’s listeria outbreak has been going on for five years.
Blue Bell facilities in Texas and Oklahoma that were found to have Listeria contamination show links to cases dating back 2010.
According to The Centers for Disease Control and Prevention, further genetics tests link the Listeria bacteria to at least six listeriosis cases with several strains of listeria monocytogenes involved in the outbreak.
Since the outbreak Blue Bell has recalled all of its products and recommend consumers to not eat and throw away any Blue Bell products in refrigerators or freezers.
The outbreak has killed three people in Kansas, and has left seven others hospitalized.
Blue Bell CEO Paul Kruse said they can’t say with certainty how listeria was introduced into their facilities but continue to work to eliminate the problem.
Blue Bell says the recalled products are distributed to retail outlets across the US and internationally.
Dr Robert Tauxe, an expert on foodborne diseases at CDC said the company is doing the right thing by closing their facilities, doing deep clean and recalling products.
“It is not the biggest outbreak, not by any means, but it is probably the longest outbreak of listeria,” said Tauxe.
