Severe storms have been ravaging the United States over the past few weeks at an intensity and frequency that exceeds peak hurricane season standards.
One major effect of these storms is the loss of power for extended periods of time.
A concern that must be considered during a blackout is how long food will keep in a closed refrigerator without power.
According to the US Food and Drug Administration, the ideal temperature for a refrigerator's interior is between 35 F and 38 F.
Every time a refrigerator door is opened, the interior temperature rises at an average of 1 F per minute. Consequently, it's imperative to keep a refrigerator closed during blackouts.
The viability of the contents in a closed refrigerator without electricity varies depending on food type.
Perishable foods (e.g. meat, fish, leftovers) can safely be eaten after four hours in a closed refrigerator during a blackout. Afterwards, these items must be thrown out.
Liquids like milk and yogurt can last up to six hours. Cheeses were developed as a preservation technique so these may last longer with softer varieties spoiling first.
Uncut fruits and vegetables have a relatively stable shelf life. They can last up to two days. Cut fruits and vegetables should be held to the four hour rule.
The temperature outside a refrigerator is a factor that must be weighed. Extremely hot weather will reduce the lifespan of food without power.
Food spoilage and shortage can be a foremost health risk during a blackout. It's important a backup stock of non-perishable goods be kept in case of power outages.
It's not possible to be overly cautious when it comes to food safety.
