Which of the following environmental conditions would increase the survival and reproduction of most food microorganisms?

A. low amount of humidity

B. high temperature

C. a temperature between 40 F and 140 F

D. All of the above

C. a temperature between 40 F and 140 F

Explanation:

Food microorganisms such as bacteria require favorable conditions for optimal growth and survival.

Option A (low amount of humidity) would not increase the survival and rapid reproduction of most food microorganisms. Rather, they need a moisture to grow rapidly. Average to high relative humidity would favor adequate moisture necessary for rapid growth.

Option B (high temperature) would decrease the survival and reproduction of most food organisms. Some food microorganisms can be destroyed by high temperature

Option C would increase the survival and reproduction of most food microorganisms such as bacteria. Temperature between between 40°F and 140°F is referred to as the "danger zone". Within this range, food microorganisms such as bacteria grow and reproduce rapidly in moist foods.
