Final answer:
Potentially hazardous foods on their way for delivery to your establishment must be kept at or below 4 degrees C (40 degrees F) to inhibit bacterial growth.
Step-by-step explanation:
Potentially hazardous foods on their way for delivery to your establishment must be kept at or below 4 degrees C (40 degrees F) to inhibit bacterial growth. This is because bacteria generally multiply most rapidly at temperatures between 4 and 60 degrees C (40 and 140 degrees F). Perishable foods that remain within that temperature range for more than two hours may become dangerous to eat because of rapid bacterial growth.
