What is the standard temperature for all coolers (including walk-in, reach-in, chef's base, and refrigerated table with drop-in section)?

• A. 32-36
• B. 34-38
• C. 40-44
• D. 28-32

Answer: (B)

Keeping cooler temperatures in the safe refrigeration zone is essential to slow bacterial growth while preserving the quality of dairy, produce, and other perishable items. The best target is the mid-30s Fahrenheit, which stays below 40°F to keep foods safe, yet above freezing to prevent freezing of sensitive items. This balance protects flavor and texture and minimizes the risk of rapid bacterial growth. If the temperature drops too low into freezing territory, items can be damaged by freezing and moisture loss; if it rises above safe refrigeration standards, bacteria can multiply more quickly. The other ranges either approach freezing too closely or sit in a zone that's too warm for safe storage, making the mid-30s range the right choice.
