d. They can be concentrated in an organism’s fat tissues.

This is referred to as biomagnification -- the POPs become more concentrated as they move from one animal to another. This is a main concern because even trace amounts, in animals at the bottom of the food chain, can cause toxicity to animals at the top of the food chain.

All of these are TCS foods except Raw unwashed asparagus.

While any food can serve as a host for pollutants, some foods are more conducive to the development of infections than others. These are TCS foods.

In order to stop germs from growing, food must get through the temperature risk zone quickly. The food must be cooled from 135°F to 70°F in just two hours, then to 41°F or lower in the following four hours.

Food must be discarded or reheated and then cooled again if 70°F is not attained in two hours. No more than six hours may pass during the entire cooling process.

As long as the meal was properly prepared and cooled before reheating, it can be served right away at any temperature.

To learn more about TCS foods refer to:
