Daily Survival: Hackers May Have Destroyed Food at U.S. Military Bases: Could Your Food Supply Be Next?

Sometime overnight in late August, freezers at a military grocery store in Arizona switched themselves into defrost mode. By morning, the food inside had been heated until it spoiled.

It wasn’t the only one. Now the Pentagon is investigating whether hackers were behind a string of refrigeration failures at U.S. military commissaries, and the answer could matter for every family that depends on a freezer full of food.

What Happened

According to Nextgov/FCW, the outages hit about six commissaries, the on-base grocery stores that serve service members and their families. Reports have named locations including Fort Huachuca in Arizona, Fort Irwin in California, and Naval Station Newport in Rhode Island.

Fort Huachuca’s commissary said its freezer went into defrost mode and heated everything inside. Other bases restricted sales of perishable food while they placed emergency orders to restock.

U.S. Cyber Command and military law enforcement units are now investigating. Officials have not confirmed a cyberattack, and it’s still unclear who might be responsible.

Why Investigators Suspect Hackers

The timing raised red flags. Earlier this month, hackers overrode temperature controls on commercial refrigeration equipment at more than 350 businesses in France, forcing supermarkets to throw out spoiled food. U.S. investigators are now working with French authorities to compare the incidents.

Federal agencies have warned about exactly this scenario for years. A 2021 Department of Homeland Security assessment flagged refrigeration failures and shipping delays as cyber risks that could cause spoilage and shortages.

Food industry security experts have also warned that attackers are targeting internet-connected industrial controls that often lack strong defenses. Modern store freezers, warehouse chillers, and distribution systems are all run by software, and software can be manipulated from far away.

The Food System Has Been Hit Before

This isn’t just a theoretical risk. In June 2025, a cyberattack on United Natural Foods, one of the largest grocery distributors in North America, left shelves empty at stores across the country for weeks.

According to TechCrunch, that attack even disrupted deliveries to 53 Defense Commissary Agency stores. Military families saw bare shelves and delayed shipments because a single distributor’s computers went down.

The lesson is simple. Your food supply depends on a long chain of computers, freezers, trucks, and warehouses, and a failure anywhere along that chain can reach your kitchen.

Could Hackers Hit Your Home Freezer?

There’s no sign that home appliances were targeted in these incidents. Most home freezers aren’t connected to the internet, although some smart refrigerators are.

The bigger risk is upstream. If grocery chains, distributors, or the power grid go down, your freezer can fail just as easily from a blackout as from a hacker. Either way, the fix is the same: be ready to protect your food when the cold stops.

What to Do When Your Freezer Fails

The USDA’s power outage food safety guidance is the place to start. Keep an appliance thermometer in both your refrigerator and freezer, with the fridge at 40°F or below and the freezer at 0°F or below.

When the power goes out, keep the doors closed. A refrigerator keeps food safe for about 4 hours, while a full freezer holds its temperature for about 48 hours, or 24 hours if it’s half full.

For a longer outage, dry ice or block ice can buy you time. The USDA says 50 pounds of dry ice should keep an 18-cubic-foot freezer cold for 2 days, but never touch it with bare hands or let it touch food.

A good high-performance cooler packed with ice is your backup for refrigerated food. And never taste food to decide if it’s safe, because when in doubt, throw it out.

Keep the Cold Running

A freezer full of meat is a big investment, and a backup power source protects it. A portable power station or a properly installed generator can keep a freezer running through a multi-day outage.

Fill empty freezer space with jugs of water. A full freezer stays cold longer, and that ice doubles as drinking water or cooler ice when you need it.

Don’t Let Your Freezer Be Your Only Pantry

The real answer is to stop depending on electricity to keep all your food safe. Generations of families kept a full larder long before home freezers existed.

Canning, dehydrating, salting, and smoking all preserve food without power. A pressure canner lets you safely can meat, beans, and vegetables, and a food dehydrator turns produce and lean meat into lightweight staples that last for months.

Pair those skills with a stockpile of shelf-stable foods like rice, beans, oats, canned meat, and peanut butter, as recommended in FEMA’s basic disaster supplies kit. That way, a dead freezer is an inconvenience, not a crisis.

The Bottom Line

Investigators still haven’t confirmed whether hackers spoiled food at U.S. military bases. But the threat to food refrigeration is real, and it’s growing.

If a coordinated attack can empty freezers on military bases and in hundreds of French supermarkets, your local grocery store isn’t immune. Protect your freezer, learn to preserve food without power, and keep a pantry that doesn’t need electricity to stay safe.
