Bacteria and thawing methods
The hypothesis that the meat thawed in the microwave oven experiences the least bacteria contamination is proven to be true.
Bacteria will contaminate meat very quickly. Leaving meat to thaw at room temperature for too long can cause the food to be unsuitable for consumption. Thawed meat should always be cooked immediately. .
The science fair project can be repeated by varying the types of food.
The experiment can also be repeated by using other thawing methods (eg. thawing the meat in a container filled with water, or in a disinfected plastic bag). .

Always follow laboratory safety guidelines and always practice sterile technique when handling microbes. Never have any food or drink at your workstation and always thoroughly wash your hands with disinfectant soap or alcohol before leaving your workstation. Always dispose of used material in a biohazard bag. If none are available, the bacteria should be destroyed with bleach before being disposed of.
