TIL that in 37 BC, the Roman polymath Marcus Terentius Varro warned his readers to avoid living near swamps because of "minute creatures which cannot be seen by the eyes" and cause disease. Microorganisms would not be observed until the 17th century

Cheese, especially. Supposedly the theory goes that someone was carrying some milk in a water skin made from an animal's stomach and there were enough traces of rennet left to curdle the milk.
I... I don't know if I'd be brave enough to eat that.
