* If you anticipate the electricity going out, set your refrigerator to the coldest temperature possible beforehand, so foods will last longer after the power outage.
* Food that is in the refrigerator, such as milk, sour cream and yogurt should be eaten first since it will spoil most quickly.
* Food that is in the freezer, such as frozen meats that can be grilled, should be eaten next. Food in a side-by-side refrigerator/freezer will stay frozen for approximately 12 hours, while food in a top or bottom mount freezer may remain frozen for up to 24 hours. Items in a separate freezer may remain frozen for 48-72 hours.
* A grill may be used to cook food, but should never be used inside the home.
* Canned good and dried foods are non-perishables but should be stored in a cool, dry place, with a note about the purchase date of the product. These foods should be eaten last, after the perishable foods are gone or have spoiled. Canned goods should be eaten within 2 hours of opening.
* Low-sodium food is a good investment, as salt will make you thirsty. If you are on a sodium-restricted diet, rinse all canned foods thoroughly before eating. Salt, however, is important in the daily diet.
* Most fruits and vegetables hold their quality at room temperature for several days.
* Water is extremely important and can be used not only for drinking, but also for rehydrating dried foods, cooking, brushing teeth, and for sanitation. At least a gallon of water per person per day (plus extra for pets) is necessary.
* If you have special dietary needs, consult with your doctor to make sure you have the recommended supplies in case of an emergency.
* Paper plates, cups, napkins, and plastic utensils are useful in an emergency, as they can simply be discarded rather than needing to be washed.
* Experts recommend at least 5-7 days of food be kept on hand if you are sheltering in place.
