My husband was served a steak in a Cracker Barrel restaurant that looked blue in the daylight. Their food comes to them from a central location (China?) already cooked and all they do is warm it up. (as told to us by the server). He didn’t eat it and we aren’t going back there.
It is possible that the place is off limit to Geiger counters.:-)
Wow! Thanks for posting... really makes you wonder “where does our food come from?” Scary stuff.
