The plight of Blue Bell Creameries continued today as a report from the U.S. Food and Drug Administration (FDA) discloses the company was aware that a deadly bacteria was present on the surfaces of its machines as early as 2013. Blue Bell ice cream has killed three people in Texas, and made people ill in Oklahoma, Arizona, and Kansas.

All the various products from the company have since been recalled as the Listeria bacteria has been found in all of its plants in Texas, Oklahoma, and Alabama. 3,800 employees continue to be laid off indefinitely.

According to the FDA, Listeria was recorded throughout Blue Bell Creameries’ Broken Arrow, Oklahoma production facility a total of five times in 2013, 10 times in 2014 and once in January 2015. The bacteria was noted on a drain, on a floor and at a “half gallon filler.”

The FDA report scolded the company for failing to effectively control “recurring microbiological contaminations.” Despite the continued positive test, Blue Bell Creameries failed to take action, it says.

Bill Marler, a food safety attorney, said that the newly released inspection reports referred to Blue Bell’s lack of action as “shameful” and amongst the worse he’s seen during his 20 years in practice. Marler represents two people who contracted Listeria from Blue Bell ice cream.

In a statement, Blue Bell Creameries acknowledged the presence of  Listeria at is Broken Arrow facility but that “we thought our cleaning process took care of any problems.” The company says it is now re-evaluating all of its operations.

Last month, 200 devotees of Blue Bell ice cream held a prayer vigil in support of the company and those who have fallen dead and ill. A pastor in Brenham, site of the company’s headquarters, referred to the ice cream as “our beloved product.”
