Blue Bell says it has found "suspected listeria species" at its Brenham facility.
The Texas-based company did not specify which facility was affected in a statement released Thursday, but it stressed that none of its products have tested positive for the infection.
The company says it expects to find small indications of listeria from time to time, but their top priority is eliminating potential sources of contamination. The company credits its new testing system for detecting what it calls "microbiological indications" of listeria. Story at WFAA.com.
