Here are some government recommendations for a 72 hour survival kit.
Consider the following things when putting together your emergency food supplies:
- Store at least a three-day supply of non-perishable food.
- Choose foods your family will eat.
- Remember any special dietary needs.
- Avoid foods that will make you thirsty.
- Choose salt-free crackers, whole grain cereals and canned foods with high liquid content.
When the Power Goes Out:
- Keep the refrigerator and freezer doors closed as much as possible.
- The refrigerator will keep food cold for about 4 hours if it is unopened.
- Refrigerators should be kept at 40° F or below for proper food storage.
- Check the temperature inside the refrigerator and freezer.
- If an appliance thermometer was kept in the freezer, check the temperature when the power comes back on. If the freezer thermometer reads 40° F or below, the food is safe and may be refrozen. If a thermometer has not been kept in the freezer, check each package of food to determine its safety. You can't rely on appearance or odor. If the food still contains ice crystals or is 40° F or below, it is safe to refreeze or cook.
- Refrigerated food should be safe as long as the power was out for no more than 4 hours. Keep the door closed as much as possible.
- Discard any perishable food (such as meat, poultry, fish, eggs or leftovers) that has been above 40° F for two hours or more.
- Under normal circumstances you should not keep dry ice in your freezer. If your freezer is functioning properly it will cause the unit to become too cold and your freezer may shut off. However, if you lose power for an extended period of time, dry ice is the best ways to keep things cold.
- Twenty-five pounds of dry ice will keep a 10-cubic-foot freezer below freezing for 3-4 days.
- If you use dry ice to keep your food cold, make sure it does not come in direct contact with the food.
- Use care when handling dry ice, wear dry, heavy gloves to avoid injury.
