How Long is Food Safe in the Fridge During a Power Outage? Insights from Allegheny County Experts

As stormy weather swept through the region, numerous neighborhoods have faced ongoing power outages, leaving residents in a scramble to protect their perishable food items. Many, like Sue from Bethel Park, are on the lookout for ice and generators to salvage their groceries. “I picked up a quarter cow of beef, but with no power, I’ve been hunting for ice to keep it safe,” she shared, highlighting a widespread concern in the community.

The Lifespan of Food Without Power: What You Need to Know

So, how long can your food last in the fridge when the lights go out? According to Amanda Mater, the Food Safety Program Manager for Allegheny County, the answer hinges on a few key factors.

Freezer Food Survival Guide

Full Freezer: If your freezer is packed to the brim, the food inside can remain safe for up to 48 hours without power. This is due to the retained cold air, allowing your items to stay frozen.

Half-Full Freezer: If your freezer is only halfway full, you can expect a maximum safety period of 24 hours. After this timeframe, the risk of spoilage increases significantly.

Fridge Food Safety Metrics

When it comes to your refrigerator, the stakes are higher. Four hours without power is the critical threshold. Anything that exceeds 40 degrees Fahrenheit for an extended period can become unsafe to consume.

Mater emphasizes: “If you’re unsure about the safety of your food, it’s better to err on the side of caution and throw it out.” Common items in danger include milk, eggs, cheese, lunch meat, and all leftovers. Trust your senses—any food exhibiting unusual color, texture, or odor is best discarded.

Maintaining Coolness: Tips for Using Coolers

For those employing coolers filled with ice, drainage is vital. Mater warns against allowing food to sit in standing water, which can pose additional health risks. To improve your odds, consider utilizing dry ice, which can prolong the cooling effect and keep perishables safer for longer periods.

A Community in Search of Power

As of Tuesday afternoon, Duquesne Light indicated that full power restoration may take five to seven days. Residents like Mike Sauter have been proactive, seeking generators to preserve valuable food supplies. "With a basement freezer stocked with several thousand dollars worth of food, I need to find a generator fast," he explained.

Unfortunately, availability remains a challenge. With many stores closed for lack of power, the search has transformed into a quest for resources. As dining establishments face long wait times due to limited operational hours, individuals are left grappling with inconvenient circumstances.

Nevertheless, community support shines as some businesses utilize generators to keep their doors open. As Sauter plans his route to buy supplies, the ingenuity of community members is on full display.
