Bacteria Love… FAT TOM

Bacteria thrive in ideal environmental conditions They die when their environment changes. These general environmental conditions are abbreviated as… I love this guy! F.A.T. T.O.M.

Food Acid Temperature Time Oxygen Moisture What is FAT TOM?

Food Bacteria are living things that need food to survive. They thrive on many types of food…

Ideal pH for bacterial growth Acid Ideal pH for bacterial growth Neutral: about 6 - 8 Acid Neutral Base pH scale

Acid Acid Neutral Base pH scale

DANGER ZONE Temperature 135°F Hot Hold 41°F Cold Hold 212°F water boils Temperature 135°F Hot Hold DANGER ZONE 74°F room temp 41°F Cold Hold 32°F water freezes

Temperature 135°F Hot Hold

Temperature 41°F Cold Hold

Temperature Freezer -6°F - 0°F Refrigerator 34°F-40°F

Temperature Cooling has to be quick Ice bath, ice stack, blast chiller

Time 4 hours DANGER ZONE After time is up, food must be thrown out!

O Oxygen 2 Eukaryotic bacteria need Oxygen to live. Prokaryotic bacteria are anaerobic Example?

Moisture H O 2 Bacteria can’t live without water.
