How do you keep unrefrigerated milk from spoiling? Frogs, of course! For centuries before refrigeration, legend goes that Russians put frogs in their milk to keep it from spoiling. Russian scientists decided to test this wives' tale. They indeed found the skin of many frogs does secrete compounds known as antimicrobial peptides, which have antibacterial properties similar to antibiotics. A compound secreted by the North American mink frog appears to fight the stubborn "Iraqibacter," an infection common in wounded soldiers fighting in Iraq. Likewise, secretions from the foothilll four-legged frog may be able to fight the MRSA staph skin infection. The Russian brown frog--considered a tasty delicacy and possibly the frog used in the milk legend--turns out to contain a cocktail of 76 peptides with possible medical benefits. So what are you waiting for? Dropping a frog in your milk not only extends its longevity but might just cure your next infection. Of course, your milk may taste a little froggy.
