HUMAN NUTRITION

Detailed explanation-1: -Food should be cooked thoroughly to kill food poisoning bacteria. The core temperature should reach 75°C instantaneously or equivalent, e.g. 70°C for two minutes. The core is taken as the centre or thickest part of the food.

Detailed explanation-2: -Food poisoning bacteria will start to multiply when chilled food is reheated to temperatures above 5ºC. They will stop multiplying when the food reaches 60ºC. The longer it takes for food to reheat to 60ºC the greater the number of bacteria that may be in the food.
