@tsarstepan,
This was done several years ago by another team of HS kids. The fact that nobody has upped any inspection requirements and food safety still seems to be pretty much of a joke, I am concerned.
PCR testing and data bases have gotten waaay better in just a few years so we could be uncovering the mysteries of food production as routine testing. Sheep milk cheese (like brie) is being passed off by some (probably) highly processed double cream cow cheese is a crime.
