According to two letters sent to the FDA in mid-February, 2016, Blue Bell thinks they have identified where the Listeria monocytogenes bacteria were living in two of its plants last year. But the problem areas were redacted in the letters that the FDA published recently, to “protect trade secrets.” The company found the pathogenic bacteria in equipment at its Brenham, Texas plant and thinks it spread in the drainage system of the plant in Broken Arrow, Oklahoma.
