You should take the temperature of the food at the core of the food. If this is not possible, (e.g. vacuum packed and frozen foods) you should measure the temperature between packs. Your temperature probe should have an accuracy of at least Â±0.5Â°C.ood should be cooked thoroughly to kill food poisoning bacteria. The core temperature should reach 75Â°C instantaneously or equivalent, e.g. 70Â°C for two minutes. The core is taken as the centre or thickest part of the food.
