Because boiling kills the majority of bacteria, preparing damaged food by cooking it may, in theory, make it safe to consume again. However, damaged food that has been prepared is not regarded to be safe for consumption at any point in time. The reason for this is that certain bacteria can withstand high temperatures or generate spores and poisons that are resistant to heat.
Is bacteria killed when spoiled food is heated?
Foodborne germs can be killed by cooking and reheating the meal properly. However, if the meal is allowed to sit out at room temperature for a lengthy period of time, certain food-borne bacteria can create poisons or toxins that are resistant to being eliminated by high cooking temperatures.
Is it safe to cook spoiled meat?
Even after being cooked, meat that has gone bad cannot be consumed safely. Even if it is able to eradicate the bacteria and molds that have colonized the area, the spores and poisons that have been left behind will still be there. If you want to prevent getting sick from food poisoning, you should always dispose of raw meat that has beyond its expiration date or if you have any reason to believe that it has gone bad.
Can food poisoning be eliminated through cooking?
