Can You Guess Which Zones in Your Fridge Are the Coldest (and Warmest)?

If you want to cut down on food waste, do yourself and your food a favor by using your refrigerator zones to your advantage. If your fridge storage strategy is merely stashing new groceries wherever there’s room, this might not be doing your groceries any favors when it comes to freshness and maximizing shelf life. According to Trevor Craig, food safety expert for Microbac Laboratories, the way you stock your fridge can have a big impact on the longevity of the food within it.

Understanding shelf life

Before we even get to the fridge, did you know that expiration dates aren’t regulated or mandated by the USDA? The dates printed on your packaged items are more a prediction of shelf life on behalf of manufacturers, rather than a guarantee of safety. “Shelf life isn’t a safety measurement. It’s a quality measurement of food for most products,” says Craig. “So that shelf life, whether it’s a couple of months or a couple of years, is actually based on how high quality they think their product is going to be over that period of time.” 

That being said, food that is improperly stored might not stay in its ideal condition throughout whatever shelf life is predicted on the label. “By maintaining a good refrigeration or proper storage, you can make sure your products last that entire shelf life, because that shelf life is based on those storage conditions,” says Craig. 

Food that is stored at improper temperatures is definitely going to degrade faster. And conversely, food that is stored correctly has a better chance of staying fresh beyond its “expiration” date. “If you’ve kept it under proper conditions, the food could still be good to eat,” says Craig. “You can extend it out a little bit further by maintaining it really well.”

Putting raw meat on the bottom of your refrigerator also prevents cross contamination. Craig recommends a top down approach as well when it comes to stocking your refrigerator for maximum quality and freshness. “Your fridge shelves are designed to help you protect your food,” he says. “The top of your fridge should be basically things that are ready to eat, and the bottom of your fridge should be more raw foods, because any of those raw things could possibly drip,” and easily contaminate your ready-to-eat items. “This is the one thing I would say that people do incorrectly all the time, and it grosses me out but probably should gross them out, too.”

Use your fridge’s designated drawers

The Container Store

You can look to TikTok for inspiration: There is value in using individual storage containers not only for ensuring food quality, but also in making it easy to clean your fridge way more often than you probably are.

“I put everything in a secondary container, so it’s not leaning against a wall,” says Craig. “And if anything bursts or explodes it’s captured within that secondary container.” Unplanned fermentation and accidental freezing are things that can cause food to burst out of its packaging in your refrigerator. 

Back to school sales are great times to look into small, shoebox-size storage containers. You’ll prevent spillage of miscellaneous juices onto the shelves of your fridge, plus it’s much easier to wash individual storage containers in the dishwasher or sink than it is to empty everything out of the fridge for periodic cleaning.

If you’ve ever stuffed your fridge within an inch of its life, you probably already know that this isn’t helping your refrigerator keep your food as fresh as possible. Before you go and throw everything out and start over, however, (especially since preventing food waste is the goal here) keeping it mostly empty doesn’t achieve optimal fridge performance either. “A full fridge does not maintain temperature very well, because it has to have some air circulation,” says Craig. “But it also has to have some items in there as an empty fridge does not maintain temperature very well.”

But according to Craig, your freezer, on the other hand, can handle being kind of stuffed: “Freezers maintain temperature better when they’re really full,” he says, but just mind that you can still close the door. “When you overfill a freezer, sometimes you’ll have problems with sealing and extra moisture. And that’s when you start to see a lot of frost.” If you need an ice chipper to remove your items, you’ll know you’ve gone too far.

Other ways to cut down on food waste

Food waste is a big problem: About half a trillion dollars of food is wasted annually, but there are plenty of ways to waste less and eat more. 

This smart app we tried connects you to restaurants to buy food for cheap before they toss it. A better understanding of expiration dates can also prevent you from unnecessarily discarding items before they’re actually spoiled. If you do have spoiled food — and it happens — try starting a compost pile or using a smart at-home food recycler like this one or this one to keep organic waste out of the landfill.
