Once power has been restored, you should not test how safe a food item is by tasting it; determining consumption safety takes a deeper and more individualized approach. 

(KLFY)-- Ever wondered what food items are safe to consume when your power is out?

During a power outage, there’s only a limited amount of time your refrigerator or freezer can keep your food items fresh. 

According to the U.S. Department of Agriculture, in the midst of a power outage, food is only safe in the refrigerator for no more than four hours. Refrigerated perishable foods like fish, eggs, meat, poultry, and leftovers are to be thrown away after being left in the refrigerator for more than four hours without power. 

When it comes to frozen foods, a freezer is capable of maintaining a safe temperature for approximately 48 hours. Foods can be adequately refrozen if it has ice crystals or its temperature is 40 degrees Fahrenheit or lower; food quality may still be affected. 

Once power has been restored, you should not test how safe a food item is by tasting it; determining consumption safety takes a deeper and more individualized approach. So how do you determine what needs to be preserved and what should be trashed?

These types of refrigerated foods are to be kept or thrown away if they’re held above 40 degrees Fahrenheit for more than two hours, according to the USDA:
