What temperature does bacteria die cold?

“The easiest way is at minus 80 degrees.” But while freezing doesn’t defeat pathogens, heat will. Bacteria die if they’re heated to 165F.

At what temperature do germs die?

140 degrees FahrenheitHot temperatures can kill most germs — usually at least 140 degrees Fahrenheit.
