Unfortunately, finding mold growing in our refrigerator is something that everyone has to deal with at some point or another, whether you are single, married, or especially if you have children. People who tend to lead fully scheduled lives from day to day typically do not have time to keep a check on the items in their refrigerator to make sure mold does not start to grow, but time should be made at the very least twice a year to clean out the refrigerator of old inventory. Those with more time to clean out their refrigerators should do so more often.
Take an inventory of what is in your refrigerator and what the date is. Anything that is sorely outdated, showing signs of mold contamination, or smelling foul should be thrown away. These items will not take long to contaminate the food that is next to it, such as potatoes from the garden that are put in the same container. One bad potato will spoil the rest fairly quickly if it is not removed and the potatoes touching it washed immediately afterward.
Fruits and vegetables that are brought home from the grocery store should be removed from their plastic sacks that we use at the store to collect them with. These bags will trap moisture inside and cause the fruit to begin to break down, inviting mold to start growing.
Clean out your refrigerator as often as possible, especially if you tend to have a lot of spills in it. If you thaw meat out in the refrigerator, you need to make sure it is thawed out in a pan of some kind to prevent the blood or other juices from getting all over your shelves. Raw poultry is notorious for causing salmonella poisoning, so it is important that you get anything the poultry touched while it was thawing in the refrigerator cleaned after you take it out.
Wash the insides of the refrigerator with antibacterial cleaners and bleach, if you must. Bleach should not be mixed with other household chemicals, however, especially those that contain ammonia. This can cause hazardous fumes to build up in your kitchen and can do you serious damage if you breathe enough in.
While you have everything out of the fridge, take the time to go through the items in it again and toss out anything questionable. Check any home-canned goods that you might have and make sure the seals are not broken on them. Throw out anything the seal is broken on, unless you broke the seal yourself not long ago.
