Final answer:
Food products in the Temperature Danger Zone should be discarded after 4 hours.
Step-by-step explanation:
When a food product is in the Temperature Danger Zone (TDZ), it means it is in the temperature range of 41°F to 135°F (5°C to 57°C). This temperature range is favorable for the growth of bacteria and can lead to foodborne illnesses. It is important to discard any food product that has been in the TDZ for more than 4 hours to prevent the risk of bacterial growth and food poisoning.
