Which food contamination is best prevented by cooking to safe temperatures

Cooking to safe temperatures will inactivate any kind of bacterial contamination, which was present. There is a need to keep the food safe from the danger zone, that is, between 40 degrees to 140 degrees F, as bacteria develop briskly in the mentioned range.  

There is a need to cook the food to safe internal temperatures. Just as the food looks done it does not mean that it is done. The best means to find that the meat, egg dishes, and poultry are cooked safely is to utilize a food thermometer.

As not cooking the food to safe temperatures signifies that bacteria may still be thriving within and may lead to illness on consumption.
