Factors affecting bacterial multiplication
Food
Microorganisms require nutrients found
in potentially hazardous food to grow
➢ Proteins
➢ Carbohydrates
Acidity
Pathogenic bacteria grow well in food
that is slightly acidic or neutral
(pH of 4.6 to 7.5)
Temperature
Most microorganisms grow well at
temperatures between 41˚F and 135˚F
(5˚C and 57˚C)
