Week 7: Gamma Rays and Microbial Genetics For this discussion, I chose Topic 1 Pro Gamma Irradiation of Food.  Would you eat gamma-irradiated strawberries?  Gamma-irradiation does extend the shelf-life but after some time, mold does begin to grow. Where does the mold come from?  Was the mold already present on the strawberries and the growth slowed by the gamma irradiation?  If gamma irradiation becomes the standard for processing produce, over time will the constant radiation e...
