Can you safely eat food if your refrigerator has had no power for a week?

It depends on the type of food and how long the power has been out. Generally speaking, perishable foods like meat, fish, dairy products, and eggs should not be consumed if the refrigerator has been without power for more than 4 hours. These foods should be discarded to avoid the risk of food poisoning. However, some non-perishable foods such as canned goods, dry goods, and unopened condiments may still be safe to eat. If in doubt, it is always better to err on the side of caution and discard any food that may have spoiled.
