That's why putting foods in the refrigerator or freezer helps to slow down the rotting process. The process of food spoilage isn't all bad, though. It's a natural process that allows nutrients from the foods, as well as seeds, to be released and used again by living organisms in the environment.

When food is harvested, either in the form of vegetables, fruits, or meats (from animals), it becomes detached from the sources that gave it life. In other words, once you pick an apple, it begins to die immediately.

Brown rot is a fungal disease of tree fruit, caused by the fungi Monilinia laxa and M. fructigena. The two fungi are very closely related and indistinguishable to the naked eye. M. laxa more commonly causes blossom wilt on pears and stone fruit, and a specific form, M. laxa f. sp. mali is restricted to apples.

Fruits like apples can rot and decay over time. Mold and fungus cause the quickest degradation, but even exposing an apple to heat can cause it to oxidize. Bruises and punctures offer the quickest route for mold and fungus to take hold. Different pathogens have different effects on rotting apples.

Brown rot on apples is normally associated with other infected fruit nearby. Brown rot is a minor disease on apples in the United States. It is caused by the fungus Monilinia fructicola, and when found on apples, it is normally associated with nearby infected stone fruits that are more susceptible to the disease. The brown rot fungus survives the winter inside dead fruit or areas of dead wood, called cankers.
