I can’t believe no one has said this, but butter going [rancid](https://foodcrumbles.com/food-spoilage-rancidity-and-food-chemistry/) is a result of a chemical reaction resulting from exposure to oxygen, not due to microbes. Butter, being pure fat, usually cannot support life very well. But the lipids can get oxidized by air causing unpleasant tasting molecules. Chemical reactions happen slower at colder temps, which is why it won’t really happen in the fridge but will happen very quickly on a very hot day.
