After just a few too many enthusiastic Costco runs (beef was on sale!) and a very bountiful farmers market haul, my fridge was packed to the brim. I didn’t suppose a lot of it till I seen my salad greens have been freezing stable. And no, they weren’t wherever close to the freezer compartment.
It wasn’t simply the greens. A container of leftovers I’d tucked away days earlier had already gone unhealthy, too. I used to be able to name a repairman — or worse, begin pricing out a complete new fridge — once I reached out to a couple meals scientists for solutions.
The Drawback: Overstuffing The Fridge
The decision? I wasn’t coping with a damaged equipment in any respect. The true downside was how I used to be utilizing it. Overstuffing the fridge was prone to blame.
“When a fridge is overloaded, vents become blocked, consequently restricting airflow and causing the internal temperature to rise and become uneven,” defined Bryan Quoc Le, a meals scientist, meals business guide, and writer of “150 Food Science Questions Answered.”

Put merely, having an excessive amount of meals has all the time been a optimistic in my Ukrainian family; nonetheless, in my fridge, it was a hazard. “Air should be able to flow around the food, ensuring that items placed inside cool quickly and remain cool,” stated Keith R. Schneider, professor of meals security on the College of Florida, in Gainesville, Florida. “If the refrigerator is overstuffed, this airflow can be blocked, allowing for ‘hot spots’ to form.”
The Dangers Of Cramming Your Fridge
Like a membership that ignores occupancy limits, an overstuffed fridge heats up quick. The cool air can’t flow into, and earlier than lengthy, you’ve received a sweaty, overcrowded equipment. Gross, proper? Now let’s get into the science.
Your lasagna from final night time is simply fit for human consumption once more if the fridge retains it at a temperature under 40°F. Nonetheless, if the fridge isn’t sustaining a cool temperature, your meals can enter the dreaded hazard zone. “Warmer spots in the fridge create danger zones, or temperatures between 40°F and 140°F at which bacterial growth is rapid, spoiling the food, and can cause food poisoning when consumed,” Le defined.
These heat pockets are likely to type within the door cabinets and again corners — the very locations many people stash eggs, milk or leftovers. That’s the place meals is most certainly to creep out of the secure zone. “Likely to warm foods include ready-to-eat foods (deli meats, leftovers, cut fruit), eggs and dairy stored far from vents are most vulnerable,” Darin Detwiler, professor of meals coverage at Northeastern College, stated. “Warming can encourage bacterial growth, especially in high-protein, moist foods. While warming increases the risk of pathogens like Listeria monocytogenes, Salmonella, and E. coli.”
And counterintuitively, your fridge can go the opposite method, too — freezing groceries that have been by no means meant to be frozen. Whereas not as harmful as meals creeping previous the hazard zone, it nonetheless wrecks your groceries. “Fresh produce, including lettuce, berries, herbs, dairy products, and liquids, can be damaged, making foods spoil faster after thawing,” Detwiler stated. Translation: say goodbye to these delicate child greens.
How To Inform If You’re Overstuffing
Whether or not it’s freezing your blended mesclun or maintaining final night time’s leftovers at a balmy 45°F, cramming an excessive amount of into the fridge can wreck your groceries, and on this financial system, nobody desires to throw meals (or cash) away.
Detweiler says these warning indicators imply your fridge is working time beyond regulation:
- You discover ice, whether or not on meals or increase across the vents (an indication chilly air isn’t circulating correctly).
- Gadgets within the door or corners really feel hotter than the middle cabinets.
- Milk, eggs or leftovers spoil earlier than their best-before date (they could be sitting in a heat pocket).
- The compressor runs consistently (it could sound like your fridge is continually wheezing).
- Condensation or moisture beads type.
- A musty or “off” odor lingers in sure spots.

Sensible Fixes And Options
Once I lastly appeared on the tiny built-in thermometer on the high of my fridge — one thing I’d been fortunately ignoring — it was hovering within the hazard zone. My abdomen dropped.
When you’ve additionally been ignoring yours, you’re not alone. However as Schneider identified, that little readout solely tells a part of the story. “Most refrigerators have a digital thermometer that shows a temperature at one location,” he defined. “If you buy an inexpensive thermometer you can place in several locations to determine the warm spots.”
One other easy repair? Don’t overstuff. Based on Detweiler, maintaining your fridge about two-thirds full is the candy spot. Too little meals makes the fridge work tougher to remain chilly, whereas an excessive amount of blocks vents and disrupts airflow.
The place you retailer issues issues, too. Dairy, eggs and different ready-to-eat meals are greatest saved on the center cabinets, the place temperatures are most secure — not within the door (the place it warms each time you open it) or within the again corners (prime territory for these cold and warm pockets).
And whereas I’d like to say I’m on high of this one, even my Virgo tendencies can’t preserve my fridge completely organized. Detweiler recommends arranging meals so older gadgets are eaten first — “first in, first out” — to chop down on waste and scale back security dangers. Perhaps someday I’ll dwell as much as my signal. Till then, it’s nonetheless fridge Jenga in my kitchen.
