People Dropped Frogs In Milk

Before refrigerators were invented, most people’s diets were very different. There’s a lot of food that just isn’t practical if you can’t keep it cold. For example, milk goes bad quite quickly without a fridge to put it in, so most people just didn’t drink it that often.

But not the Russians. The Russians found a different solution. They put frogs in their milk.

In some parts of Russia, people would drop frogs into buckets of milk to keep it from spoiling. That sounds a little strange, but oddly enough, it actually worked. The frogs’ skins were coated in an antibiotic peptide that kept bacteria from contaminating the milk, which actually made it safe to drink for a longer time.

Not that the Russians knew that. We didn’t figure that out until about five years ago. The people who did this had no idea that the frogs were keeping their milk from going bad until just recently. They were just dropping frogs into milk for reasons that no one can quite explain.
