A California company has found a breakthrough when making raw milk safe to consume

‘Tamarack Biotics’ has secured initial FDA acceptance of using UV light for milk safety

A California company, Tamarack Biotics, is working to elevate milk safety, but they are not using traditional sources, like heat. Instead, they are using ultraviolet light.

“It’s kind of difficult to pasteurize milk with ultraviolet light because it doesn’t penetrate into the milk, so you have to do it in very thin films and with very high turbulence to renew the surface frequently, and that enables you to kill all the bad bugs and milk very effectively. In fact, we are more effective than heat at killing all the bad bugs,” said Tamarack Biotics CEO Bob Comstock.

The company has secured initial FDA acceptance for their design.
