A scheme was developed to isolate the most radiation resistant vegetative microbial cells occurring in beef. Selection of pure cultures and enrichment provided 16 apparently different isolates with higher radiation resistance than spores of Clostridium botulinum. Most of these bacteria were found to be Moraxella or Acinetobacter. They grew over a temperature range of 2 - 50 C. Preliminary data indicated the isolates to be relatively sensitive to heat and to limited oxygen. It would appear these organisms are rather widespread and frequent in nature.
