SNHD Temperature Danger Zone 2

Question 1

What is the temperature range of the Temperature Danger Zone (TDZ) according to Nevada food safety regulations?

Accepted Answer

41°F to 135°F (5°C to 57°C)

Answer

The Temperature Danger Zone in Nevada follows the FDA Food Code: 41°F to 135°F (5°C to 57°C). Bacteria multiply most rapidly in this range, potentially doubling every 20 minutes under ideal conditions.

Question 2

TCS food left in the Temperature Danger Zone for more than how many cumulative hours must be discarded?

Accepted Answer

4 hours

Answer

TCS food that has been in the Temperature Danger Zone for a cumulative total of more than 4 hours must be discarded. After 4 hours, bacterial populations may have reached dangerous levels that cannot be corrected by cooking.

Question 3

A pot of soup is removed from the stove and placed on a counter at room temperature (72°F) to cool before refrigeration. What is wrong with this practice?

Accepted Answer

Cooling at room temperature keeps the soup in the TDZ for too long, allowing dangerous bacterial growth

Answer

Cooling TCS food at room temperature keeps it in the Temperature Danger Zone for an extended period, allowing bacteria to multiply to dangerous levels. Nevada regulations require the two-stage cooling method for hot TCS foods.

Question 4

Which of the following foods is a TCS (Temperature-Controlled for Safety) food that must be kept out of the Temperature Danger Zone?

Accepted Answer

Sliced cantaloupe

Answer

Sliced cantaloupe is a TCS food. Once cut, the protective rind is removed, the water activity and pH of the flesh support bacterial growth, and the food must be kept cold at or below 41°F.

Question 5

During a buffet service, hot TCS foods must be held at a minimum temperature of:

Accepted Answer

135°F (57°C)

Answer

Hot TCS foods must be held at a minimum internal temperature of 135°F (57°C) during buffet or steam table service to keep them out of the Temperature Danger Zone.
