What happens to bacteria in -18 degrees
Bacteria are dormant in the freezer (still alive)
What happens to bacteria at 1-4 degrees
Bacteria multiply slowly in the fridge
What happens to bacteria in 5-63 degrees
DANGER ZONE!!!!
Bacteria multiply rapidly between 5-63 degrees
What happens to bacteria between 64-100 degrees
Bacteria are destroyed between 64-100 degrees
What does dormant mean?
Dormant means inactive. The bacteria are alive, but not actively growing or multiplying.
What is also essential along with food,moisture and warmth
Time
What happens to bacteria in 20 minutes
