According to the Centers for Disease Control (CDC), the listeria outbreak that prompted Blue Bell Creameries to recall their entire product line dates to 2010, reports CNN.
After weeks of gradual recalls, the company recalled all its ice cream, frozen yogurt, sherbet and other frozen treats sold in 23 states because they could be contaminated with Listeria monocytogenes. The bacteria can cause serious and sometimes fatal infections in young children, the elderly and others with weak immune systems.
The CDC recommends consumers do not eat any Blue Bell brand products. Blue Bell has now had several positive tests for Listeria in different places and plants.
Blue Bell CEO and President Paul Kruse promised to make sure all products are safe before they go back on sale.
