The joint investigation found that certain Blue Bell Creameries ice cream products, including bars, scoops and cookies, were the likely source for some or all of these illnesses. Upon further investigation the CDC said Blue Bell ice cream had evidence of Listeria bacteria in its Oklahoma manufacturing plant as far back as March 2013. The outbreak led to 3 deaths in Kansas.Blue Bell was the nations third most popular ice cream brand. The items came from the companys production facility in Broken Arrow, Oklahoma . The CDC stated that all five of the sickened individuals, including the three older people who died, were receiving treatment at the same Kansas hospital before developing the listeriosis, suggesting their infections with the Listeria bacteria were nosocomial (acquired, while eating the products, in the hospital). Their pre-existing weakened conditions might help to explain the higher mortality rate in these cases (60%, versus the more normal 20–30%).On April 20, 2015, Blue Bell issued a voluntary recall of all its products, citing further internal testing that found Listeria monocytogenes in an additional half gallon of ice cream from the Brenham facility. 2015–18 European listeriosis outbreak
