Irradiation does not prevent cross-contamination

Irradiation flogs come out every food scare.  On closer examination, the PCA plant that produced the salmonella peanut butter did in fact include a sterilization step - simply using a different form of sterilization would not fix the fundamental problems.  Until we get rid of the emphasis on profit in the food chain, corrupt practices, filthy conditions and improper storage will continue to the advantage of the producer and the detriment of the consumer.
