Do YOU Have a Plan to Keep Food Safe during Severe Weather?
This year has been an important reminder that disaster can strike anytime and anyplace. Nearly every region of the country experienced some form of extreme weather event, including wildfires in the west, extreme cold and snow through the Midwest and East, and destructive tornadoes in the South and Central Plains.
All of these events resulted in the loss of power for hundreds of thousands, and without power comes food safety challenges. The temperature and sanitation of food storage areas is crucial to preventing bacterial growth, and severe weather and other emergencies can compromise this. Knowing what to do in these instances can minimize the need to throw away food and the risk of getting sick.
September is National Preparedness Month and America’s PrepareAthon. These are a coordinated national awareness campaign to get families and communities thinking about how to respond in the event of a disaster or other emergency. The USDA’s Food Safety and Inspection Service is joining the effort by helping people plan to keep their food safe in case of hurricanes, flooding, fires, power outages and other emergencies that threaten storage conditions.
Before the Power Goes Out (if there’s time)
- Keep an appliance thermometer in the refrigerator and freezer. The refrigerator temperature should remain 40 °F or lower, and the freezer should be 0 °F or lower.
- Store food on shelves that will be safely out of the way of contaminated water in case of flooding.
- Freeze refrigerated items such as leftovers, milk and fresh meat and poultry that you may not need immediately – this helps keep them at a safe temperature longer.
- Have coolers and frozen gel packs on hand to keep refrigerator food cold if the power will be out for more than 4 hours.
- Purchase or make ice and store in the freezer for use in the refrigerator or in a cooler.
When the Power Goes Out
- Keep refrigerator and freezer doors closed as much as possible.
- A refrigerator will keep food cold for about 4 hours if you keep the door closed.
- A full freezer will keep its temperature for about 48 hours (24 hours if half-full).
- If the power is out for an extended period of time, buy dry or block ice to keep the refrigerator as cold as possible. Fifty pounds of dry ice should keep a fully-stocked 18-cubic-feet freezer cold for two days.
After the Power Returns
- When the power comes back on, you will have to evaluate each item separately. When in doubt, throw it out. These charts help you evaluate specific foods:
- With frozen food, check for ice crystals. The food in your freezer that partially or completely thaws may be safely refrozen if it still contains ice crystals or is 40 °F or below.
- Discard any food that has an unusual odor, color, or texture, or feels warm to the touch.
- Never taste a food to determine its safety.
Anyone with questions about the safety of their food as a result of weather damage and power outages is encouraged to call the USDA Meat and Poultry Hotline at 1-888-MPHotline (1-888-674-6854) or chat live with a food safety specialist at AskKaren.gov, available from 10 a.m. to 4 p.m. ET, Monday through Friday, in English or Spanish.
