What are safe and sanitary practices in the use care and storage of food and equipment?

Some, but not all kinds of food have to be refrigerated. Food has to be stored in clean, preferably sterile conditions to avoid the growth of bacteria, mold, etc. Food has to be protected from insects, rodents, or anything else that might want to eat it before it gets to the people for whom it is intended. Food must be free of contamination, so don't allow anything to get into it, not even dust.
