Final answer:
Most fresh vegetables should be stored at a refrigerator temperature of 40°F (4°C) to inhibit bacterial growth and extend their freshness.
Step-by-step explanation:
The temperature at which most fresh vegetables should be stored is 40°F (4°C). This is to prevent the rapid multiplication of bacteria and other microorganisms, which tend to grow most rapidly between 4°C and 60°C (40°F and 140°F). Refrigeration at or below 4°C helps inhibit bacterial growth, keeping vegetables fresh for a longer period. Ensuring good ventilation along with the correct refrigeration helps in maintaining the quality and safety of fresh produce.
