***Sorry. I used to teach food handling safety to young airmen,***
USAF I presume? The worst case of runs I ever saw was at Walker AFB in Roswell NM back in 1967.
We had two chow lines. One for the main dinner and one for fast food. One day I went in and the main dinner line was packed! I went to the fast food hamburger line.
The next day everyone who ate the main dinner had the runs bad! Those who went through the fast food line missed it.
The cause was traced to bad pork steaks in the main dinner line.
It was funny while working on a B-52 to see a top Sgt suddenly run like h#!! behind the blast fence, then beg one of the airmen to run and get him some toilet paper.
Yep. I was USAF active the first time, reserve after 9/11. Services was the only job I could get after 9/11 because of hearing loss. Turns out I loved the kitchen.
I'm harsh on sanitation and dates/temps for foods. You can't fight a war sitting on a toilet.
