The only way to reduce the amount of germs to safe levels in TCS foods is by

• A. Cooking to the required temperatures
• B. Adding spices
• C. Holding at room temperature
• D. Marinating in oil

Answer: (A)

Heating foods to their required internal temperatures is the method that reliably lowers the number of germs in TCS foods to safe levels. When food reaches the specified temperature for the right amount of time, heat denatures microbial proteins and destroys or inactivates most pathogens that can cause illness. This direct kill effect is why cooking is the primary safety measure.

Adding spices won’t kill germs; they only flavor. Holding foods at room temperature gives bacteria freedom to multiply to dangerous levels. Marinating in oil doesn’t reliably kill microbes either. Safe handling also means proper cooling and storage after cooking to keep the food safe.
