If your refrigerator and freezer(s) are without power, please read through the following resources about food safety, published by the U.S. Department of Health and Human Services. Information includes what to save and what to throw out, and what to do upon returning home after an emergency. When is thawed food safe to eat? All the information you need to know can be found on this website. The general rule of thumb: Discard any perishable food (such as meat, poultry, fish, eggs, and leftovers) that has been above 40 °F for over 2 hours.
