ABSTRACT

The discussion of biological effects of ionizing radiation in Chapter 4 has already touched on certain questions related to the microbiological safety of irradiated foods. In the present chapter these questions will be considered in more detail.

In foods some microorganisms survive a nonsterilizing dose of radiation. As described previously, different species or strains of microorganisms differ in their radiation resistance. The surviving microflora will therefore differ in composition from the flora present prior to radiation treatment.
