I've been following the recent info on the expired food at the school cafeterias and I want to weigh in with my two cents.
Back in the late 70's & 80's, I was employed at the Health Dept. and one of my jobs was to inspect the school cafeterias. We were trained to check the dates on all food products to be sure that they were safe to serve. If we found one or two items with expired dates, we were to have the cafeteria manager open them, and then throw them in the trash. If we found a large quantity of an item, such as a crate of milk cartons, they were tagged, the manager was to call the supplier, while we were there, to have them come and get the crate and replace it. The out of date items had to be destroyed by the supplier (as I watched). This did not happen often. Back then the cafeteria workers actually prepared the meals and they were extremely conscientious of these issues. (Plus the food was MUCH better). As to out of date food being taken out of packages, rinsed and then re-packaged, this is not a safe practice. Rinsing off out of date food will not remove bacteria.
I'm sure the rules have changed since I was a food inspector and are more strict now. I can not imagine the Health Dept. encouraging the practice of rinsing off out of date food products and repackaging them
Thanks for letting me add my thoughts.
