Before refrigeration, Russians kept the milk fresh by dropping live brown frogs straight into their milk buckets. The frog’s presence kept milk from spoiling, but no one knew why.

The skin of brown frogs, Rana temporaria, releases a unique secretion packed with potent antibacterial and anti-fungal peptides, making it a natural defence mechanism against both bacteria and fungi.
