Apparently there's a thing being used called Food Irradiation.
When I was working in a meat store I got lots of people coming in and asking too many questions about irradiation, seemingly as an excuse to then launch into a rant about the food industry.
I agreed with half of what they said, but I needs to get paid, and big brother corporation gave me a damn script to talk about, so stop trying to fight the good fight against an hourly minimum wage associate!
It's not like I can somehow stop the cattle industry from stuffing corn down the throats of thousands of cows a year.
"Oh! You prefer grass-fed beef... Sorry.... Lemme just go grab the grass fed product from its hiding place in the back! I save it for people who bitch the most and don't buy anything."
