Milk
This was originally the front page of my master thesis (at least after the university mandated official front page). The full thesis is available here: https://nmbu.brage.unit.no/nmbu-xmlui/handle/11250/2678490
It’s in norwegian, so it might be hard to understand. Sorry about that. But I can confirm that cows milk can contain antibiotic resistant bactieria, which was great for my thesis but also kind of scary.
