WAYS TO KEEP FOOD SAFEPeople who grow their own food usually want to keep enough from their harvest for future use. But they also want to avoid the risk of food poisoning. So food safety experts offer some advice. One suggestion is to carefully examine vegetables that grow underground before they are put away for later use. They should be clean, dry, and have no cuts. They should be kept in a cool, dry place. Meats, fruits and vegetables can be dried and kept in cloth bags. The bags should be hung in a cool, dry place. Hanging the bags in the air will keep animals and insects on the ground from damaging the food. Fresh bread can be kept for later use if it is cooled quickly after it is baked.
