Cooking is the thermal heating of foods at sufficient temperature over time to kill microorganisms in the food.
The following are the requirements for the different foods:
Plant food for hot holding: 135°F – Temp Unchanged – Hold for 15 seconds (See table below)
Beef (BEEF STEAK), Fish, Seafood, and Eggs: 145°F – Temp Unchanged – Hold for 15 seconds (See table below)
Pork: 145°F – PORK CHOPS-- Temp Unchanged – Hold for 15 seconds (See table below)
Poultry, Food Containing Poultry, Stuffed Meats or Stuffing Containing Meat, Casseroles, or Food Containing Potentially Hazardous Foods: 165°F –Temp Unchanged BUT no longer hold for 15 seconds. New directives – INSTANTANEOUS – See table below)

Restructured Meat, Ground or Fabricated Meat: 155°F – Temperature Changed to 158°F-- ALSO no longer hold for 15 seconds. New directives – INSTANTANEOUS
Cooking requirements are based on the biology of pathogens. Different species of microorganisms have different susceptibilities to heat.
