Bacterial growth follows a regular pattern that consists of four (4) phases:
Lag Phase
- Bacteria exhibits little or no growth.
- Last only a few hours in room temperature and can be decrease by keeping food out of the temperature danger zone.
Log Phase
- Bacteria double in numbers in every 15 to 30 minutes.
Stationary Phase
- Number of bacteria is steady as the new organisms being produced is equal to number of organisms that are die.
Death Phase
- Bacteria die off rapidly because they lack nutrients and are poisoned by their own wastes.
