Milk is drank all over the world and therefore, I would imagine that the whole world has problems keeping their milk fresh after it leaves the cow (or goat or whatever). Not everyone around the world has a refrigerator or ice box or even ice. If you didn't have a way of keeping your milk cold, how would you go about keeping it fresh?
It was reported that people living in Russia and Finland would drop living frogs in milk to keep it fresh. OK, you may never drink milk again. . . actually, it has been many, many years since I have drank milk. I prefer to get my milk in ice-cream (grin).
Sometimes these odd customs, when checked out by science, have some basis after all and this one is no exception. The Moscow State University did some research and discovered that amphibians' skin secretions are loaded with peptides. These peptides are antimicrobial compounds and they are as potent against Salmonella and Staphylococcus bacteria as prescription antibiotics. So, now I am going to have to learn how to milk a frog's skin. While I try to figure that out I want you all to have a great day, you hear?
