food storage can be done on a small scale in households. Plenty of frozen, preserved foods can be stored in freezers and pantries. Emergency kits that contain food, water, stoves, lights, and heaters etc which are available at reasonable cost can be purchased for all the family members. On occasions when people are forced to stay in basements during cyclones and other typhoons that are passing by, or when people get snowed in when there is more than the usual amount of snowfall, these kits will tide them over for a few days till better conditions prevail or till help arrives, whichever happens first.
Large scale food storage are followed by Government departments and agencies to stock enough food in granaries and huge buildings and freezers meant for that purpose. There are many innovative processes that have been discovered in the last century for better and more effective ways of food storage. Some of them are irradiation procedures where concentrated beams of different kinds of rays destroy harmful micro-organisms and stop contamination processes from starting. Freeze- drying and such other cold storage procedures ensure that frozen food, vegetables and other stay fresh for months together. Dehydration procedures reduce or remove water content so that the grains do not rot.
