Which characteristic makes a food a time/temperature control for safety (TCS) food?

• A. Low Moisture Content
• B. High pH
• C. High Moisture Content
• D. Freeze-Dried

Answer: (C)

Time/temperature control for safety (TCS) foods are those that can support rapid growth of pathogens if not kept at safe temperatures, and the key factor that makes a food TCS is its moisture availability. High moisture content means more water activity is available for microbes to grow, so these foods require strict time/temperature controls to prevent bacterial multiplication. Foods with low moisture or dried forms have little water for microbes and are not considered TCS. While pH can influence growth, it isn’t the defining characteristic here, and freeze-dried products have very little moisture and aren’t TCS unless they’re rehydrated to a moist state.
