Does boiling milk kill viruses?
BOILING AND PASTEURIZATION
Boiling water kills or inactivates viruses, bacteria, protozoa and other pathogens by using heat to damage structural components and disrupt essential life processes (e.g. denature proteins). Boiling is not sterilization and is more accurately characterized as pasteurization.
Is it OK for milk to boil?
Boiling raw milk kills microbes and makes the milk safe to drink. Pasteurized milk is safe to drink cold, but boiling may extend its shelf life. If you just need to heat milk for cooking or to enjoy a warm cup, scalding it is faster and easier.
