Blue mold is a fungus that commonly affects fruits that are put into cold storage; the mold develops quite slowly at these cold temperatures. When it is brought to room temperature, green mold (which does not grow well in cold temperatures) predominates most infections where both molds are present. Blue mold is actually Penicillium italicum and is not as serious as the green mold that occurs in Florida. The spores become airborne and grow large colonies on the surface of fruit that have become infected. They will go on to contaminated the equipment, water in any tank the fruit comes into contact with, the packinghouse, transit containers, any storage room, and eventually the retail market area if the infected fruit is allowed to travel that far.
The fungus survives outside of the fruit packing industry in soil debris and since the spores are airborne, they can infect fruit on the tree or on the ground whose skin is damaged. Any infected fruit that is boxed with healthy fruit will cause the whole carton to become infected and care should be taken to remove any diseased fruit from the lot as soon as possible. Before it makes it to the retail market, any diseased fruit must be removed. The cycle of producing spores and infecting fruit can be repeated a great number of times in storage rooms and fruit packing houses and since this is true, it will eventually develop a strain that has a resistance to any chemical fungicides.
The symptoms of blue mold appear similar to sour rot or green mold; a small area of decay begins to form and this manifests as a soft, somewhat watery spot. These lesions will enlarge to about 1 to 2 inches in diameter and white mycelium will form in the center. Blue spores will begin to form shortly afterward and these are easily turned airborne by either moving the fruit around physically or by a simple air current in the room.
To reduce the incidents of blue mold, both harvesting and handling of the fruit needs to be very careful. High populations of blue mold spores cannot be let to gather in the storage rooms or packinghouses. Any fruit that is infected should be removed from the area where clean fruit is located immediately and put in a different facility used especially for disposing of it. Equipment should be sanitized on a daily basis.

Mold Fun Facts
Mold is everywhere around us. Be it indoors or outdoors. It is simply there. There is no such thing as a mold-free environment on this planet, or any other. There are three things that mold absolutely must have to survive. And the only time that mold is visible to the naked human eye is when large colonies begin to grow and gather. Previously stated was the fact that there are three things that mold need to survive.
First of all, mold requires nutrients. And if the mold was in an outdoor environment, these nutrients would most likely be acquired from organic matter like dead animals or dead plants. This is natural and necessary so that debris that builds up from the cadaver of the animal or plant. The mold causes decomposition and that helps the fertilization product in plants. The mold can also inhabit discarded trash such as cardboard, paper, pieces of drywall, fabrics, and other kinds of dust.
Another key element that is essential to the survival of mold is moisture. The decaying of organic matter requires moisture. As does the digesting of the organic matter by the mold. In fact, the highest numbers of cases of mold infestation occur during the summer time, when there is high humidity, and therefore higher condensation. This condensation gathers inside of a house. Winter time is also a bad time for homes, because certain areas can become drafty, and that can lead to condensation build up.
Something else that mold requires is something that there is an unlimited supply of. And that would be: time. Mold simply requires the time to grow. It can start a colony, after it has gained a sufficient amount of nutrients and moisture, in up to twenty four hours. And if something like a wet towel or piece of clothing is simply allowed to sit, then the mold is simply being handed enough time to gather in size and in number.
The last thing mold requires in order to survive and continue to spread is heat. Most molds do not even require an exponential amount of heat in order to spread. However, a good number of molds need it. Molds have been known to remain dormant at extreme temperatures while not growing. They stay in a kind of suspended animation. This goes for cold temperatures as well. They can be exposed to temperatures near two degrees Celsius, and they would revert to this state of suspended animation.
