Texas-based Blue Bell Creameries issued a voluntary recall Monday night for all of its products on the market after two samples of chocolate chip cookie dough ice cream tested positive for listeriosis.
The company "can't say with certainty" how the bacteria was introduced to the manufacturing line, Blue Bell's chief executive Paul Kruse said in a statement.
"We're committed to doing the 100 percent right thing, and the best way to do that is to take all of our products off the market until we can be confident that they are all safe," Kruse said.
The first recall in the family-owned creamery's 108-year history was issued last month after the U.S. Centers for Disease Control and Prevention linked ice cream contaminated with listeriosis to three deaths at a Kansas hospital. Five others in Kansas and Texas were sickened with the disease.
