1. The dangerous range of temperature between 40 degrees F and 140 degrees F when most bacteria can grow and reproduce rapidly to infective doses.
2. Those areas most prone to breakdowns in good handwashing and gloving practices.

DEVIATION
Failure to meet any critical limit.*

DIARRHEA
Three or more loose stools within a 24-hour period. Bacteria, parasites or viruses can cause diarrhea.

DILUTION

DISINFECTION
The reduction (by chemicals or physical methods) of the number of microorganisms in the environment, to a level safe for food preparation and consumption.*
