Having a dirty fridge is more then just gross, it can actually be harmful to your health. Most people only thoroughly clean their fridges when they are moving, especially under it. The horrors under fridges are unlike any mess you’ve ever seen.
Anyway scientists say that fridges should be cleaned and disinfected regularly. Scientists studied and realized that household fridges found that 64.3% of them had the potential to cause staphylococcal food poisoning.
It is believed that many of the Staphylococcus bugs in fridges could be of animal origin. And many of the food in fridges could have the bug on them, such as cheeses, raw meats, and cold cooked meats. Staphylococcus of animal origin may get onto food that is going to be eaten raw and if food is taken out of the fridge and kept at room temperature, the organisms that can cause the food poisoning will grow. Cooked foods that are going to be eaten should be kept at the top of the fridge so that parts of other foods do not fall down on them and contaminate them.
Obviously raw food should be kept away from the fresh foods, and all foods and general.
This is what you want your fridge to look like.
