Which category of foods requires Time / Temperature Control to prevent hazards?

• A. Non-perishable foods
• B. TCS foods
• C. Frozen foods
• D. Dried foods

Answer: (B)

Foods that require Time/Temperature Control for Safety are those that can support rapid growth of harmful microorganisms if left at unsafe temperatures. These foods are typically moist, nutrient-rich, and have a neutral to mildly acidic pH, which lets bacteria multiply quickly when they sit in the temperature danger zone (about 41°F to 135°F, or 5°C to 57°C). To prevent hazards, they must be kept hot at 135°F (57°C) or above, or cold at 41°F (5°C) or below, and they should be cooked, cooled, reheated, and held with careful temperature and time management. Examples include dairy, eggs, meats, poultry, seafood, cooked grains, cut or prepared produce, and foods with sauces or gravies.

Non-perishable foods are shelf-stable because their moisture or water activity is too low to support growth, frozen foods are kept at temperatures that stop growth, and dried foods have very low moisture, which also limits microbial growth. These characteristics mean they don’t rely on strict time/temperature control to prevent hazards in the same way TCS foods do.
