Scientists are rethinking the dates consumers see on food packaging — and their research could help reduce not only food waste but also economic losses and environmental impacts tied to discarded food.
Here’s the claim in the Post article that caught my skeptical eye:
“The average American wastes more than 1,000 pounds of food each year,” according to Auburn University researchers.
Part of the reason is that sell-by dates are overly conservative, the researchers said in a news release announcing their work to predict spoilage more accurately.
The findings could help consumers make more informed decisions about food safety while reducing unnecessary waste throughout the supply chain.
“This research is far more significant than a discussion about meat discoloration or shelf life,” Darin Detweiler, a food safety policy expert and professor at Northeastern University’s College of Professional Studies, told Fox News Digital.
“It is an example of how data, microbiology and artificial intelligence may help transform food systems from managing failure after it occurs to predicting and preventing inefficiencies before they happen,” he said. (Detweiler was not involved in the new research.
The Auburn study focuses on meat sell-by dates, which are commonly used by retailers to indicate how long products should remain on store shelves.
A change in color doesn’t necessarily mean meat is unsafe to eat. Sell-by dates for meat are typically four days after packaging, the news release said.
They’re “based on when the beef will start to lose its bright pink color, rather than when it becomes unsafe to eat.”
A change in color doesn’t necessarily mean meat is unsafe to eat, however.
Hey, not to worry, it’s just “quality degradation” — whew!
“If a consumer sees that on day three their meat is brown, and it’s around the ‘sell by’ date, they might think it’s spoiled, but in fact it’s just quality degradation,” said Isabella Gafanha, an Auburn master’s student who was involved in the research. “It’s still fine to eat.”
The Auburn researchers used a machine to track changes in microbial communities in packages of ground beef over the course of 14 days. The goal was to “associate those changes with key changes in the meat quality and indicators of spoilage.”
Researchers monitored microbial activity in ground beef packages over a two-week period, using predictive modeling to identify patterns that could signal spoilage before it becomes visible to consumers.
14 days? Here’s a fun fact:
Fresh ground beef will last in the refrigerator for one to two days.
The reason ground beef only lasts up to two days in the refrigerator is because it contains specific characteristics that bacteria like to grow and thrive. “Ground beef provides a high protein that pathogenic bacteria love to grow especially at temperatures between 40 to 140 degrees F, but they can still grow (just slowed) at refrigerated temperatures. If given enough time, this will allow pathogenic bacteria to grow to high levels that can make people sick,” Amidor explains. “Ground beef also has the moisture levels and pH level that these pathogenic bacteria like. Although the temperature is around 38 degrees F, the bacteria can still grow but at a slower rate and the maximum time that is safe is up to 2 days.”
Back to the “journalism”:
….. Researchers plan to continue their work to create more accurate sell-by dates while reducing the pounds of meat unnecessarily discarded each year. [whatever the quantity of wasted beef, it’s nothing compared to the volume of bullshit propounded by the food-waste-reduction crowd, active here in Greenwich, as well as the rest of the country].
The economic implications of the research are “enormous,” Detweiler said.
When meat is discarded, producers lose out on costs associated with animal feed, transportation, processing, packaging and more. Retailers also lose when they are forced to remove unsold products from their shelves.
“If predictive microbial modeling allows shelf life to be extended safely by even one or two days, the cumulative impact across the beef industry could represent hundreds of millions of dollars in recovered value annually,” Detweiler said.
“From a leadership perspective, this represents a rare opportunity where profitability and sustainability may align rather than compete,” he added.
The research could also benefit the environment in a major way, he said.
“Food waste is one of the largest hidden environmental burdens in the food system,” Detweiler said.
“Every pound of beef discarded represents wasted water, land, feed, energy and transportation emissions. Beef production has one of the highest environmental footprints among food commodities.”
The domino effect of the Auburn research has the potential to help people facing food insecurity, Detweiler said.
“While extending shelf life alone will not solve hunger, reducing avoidable waste contributes to a more efficient and responsible food system,” Detweiler said.
Consumers may also benefit, he said, from reduced food costs if food producers and retailers are able to safely reduce waste-related losses.
To ensure food safety is prioritized and consumers are protected, companies must apply this research and technology beyond increasing profits, Detweiler said.
“A longer shelf life must still be validated through rigorous food safety science and regulatory oversight,” he said. [You know, safety science like that applied to COVID “prevention” and vaccines — “trust us, we’re experts.”]
The researchers indicated that additional work is needed before predictive spoilage modeling could be broadly adopted by the meat industry, but they believe the early results demonstrate the technology’s potential to improve food dating practices and reduce unnecessary waste.
One of the great things about AI is that, in the past, you’d read or hear a statistic thrown out by some pressure group or another and, although you’d know it it was bullshit, it was too much trouble to track down the actual facts; you’d just dismiss it and go on with life.
That’s probably still the best approach to phoney claims and life in general, but as a professional cynic, I’m really enjoying the ability to have these doubtful claims verified or debunked in mere minutes, even seconds. Like this:

Q: I just read a claim that " The average American wastes more than 1,000 pounds of food each year". I may be the exception, but I don't throw away, let alone "waste" anything approaching that number, and I'm skeptical. "Waste", to me, means otherwise edible food that's needlessly thrown out, and I don't believe we're so profligate. Are the "researchers" including things like grapefruit rinds and coffee grounds in their calculation?
A: Your skepticism is justified, and the answer depends heavily on what the author meant by waste.
The commonly cited numbers for Americans are usually in the range of 240–350 pounds of food per person per year, not 1,000 pounds. The USDA and EPA estimates that 30–40% of the food supply goes uneaten translate into roughly that range on a per-capita basis.
The key issue is that many studies use "food waste" in a broad, technical sense rather than your everyday sense of "perfectly edible food that someone foolishly threw away."
Researchers often distinguish:
Edible food waste — food that could have been eaten but wasn't.
Inedible food parts — banana peels, orange rinds, coffee grounds, eggshells, bones, etc.
Food loss earlier in the supply chain — crops left in fields, spoilage during transport, unsold supermarket food, restaurant waste, and so on.
A recent national household study explicitly reported both numbers. Households wasted about 3 pounds per week of edible food, but 4.5 pounds per week when inedible scraps were included. The researchers specifically mention eggshells and other food scraps in the latter category.
Another analysis similarly found roughly 2.1 pounds/week of edible food, rising to 3 pounds/week when inedible parts like chicken bones and banana peels were included.
So if someone quotes a figure near 1,000 pounds per American per year, I'd immediately want to know:
Are they counting only household trash, or the entire food system?
Are they including inedible portions?
Are they including farm, retail, and restaurant losses that occur before food ever reaches consumers?
For example, if you start with the claim that roughly one-third of the U.S. food supply goes uneaten, and then allocate all those losses across the population, you can get surprisingly large per-person numbers. But that does not mean the average individual is personally tossing 1,000 pounds of edible food into the garbage.
One other reason these numbers feel implausible is that food is mostly water. A gallon of milk weighs about 8.6 pounds; a watermelon can weigh 15–20 pounds. It doesn't take as much discarded mass as people intuitively imagine to add up to a few hundred pounds per year. Still, 1,000 pounds is far above the household-level estimates I've seen.
If you can share the exact article or quote, I can track down the original study and see precisely what was being counted. My guess is that the figure either:
includes inedible scraps such as peels, rinds, grounds, and bones,
allocates supply-chain losses to individuals,
or is referring to food produced for each American that never gets eaten, rather than food each American personally throws away.
Q2: Here's the NYPost article that I read: “ https://nypost.com/2026/06/05/health/scientists-say-one-common-mistake-leads-to-throwing-away-perfectly-good-meat/” It attributes the 1,000 lb figue to a study conducted by Auburn University researchers, but provides no link to the study itself.
A: I tracked down the source of the quote. The New York Post article is quoting an Auburn University news release that states:
"The average American wastes more than 1,000 pounds of food each year."
What's notable is that neither the Post article nor the Auburn release (as quoted in the article) explains how that figure was calculated.
That immediately raises a red flag for me, because there are at least three very different quantities that often get conflated:
MeasureTypical magnitudeEdible food discarded by householdsA few hundred pounds/person/yearHousehold food discarded including peels, bones, grounds, etc.Higher, but still generally well under 1,000 lbTotal food produced for each American that never gets eaten anywhere in the supply chain (farm, transport, retail, restaurants, homes)Can approach or exceed 1,000 lb/person/year
The last category is the one most likely to generate a figure above 1,000 pounds. If a lettuce crop is plowed under, a supermarket discards unsold produce, and a restaurant throws out leftovers, those losses are often allocated across the population and reported as "X pounds per American." But that's very different from "the average American throws away 1,000 pounds of food."
Your intuition about grapefruit rinds and coffee grounds is also on target. Many food-waste studies count food discards by weight, which often includes:
Those materials are biologically "food waste" in the waste-management sense, even though nobody would consider them edible food that was squandered.
Another clue is that the Auburn research itself was about extending the shelf life of ground beef by using microbial modeling to avoid premature disposal based on conservative sell-by dates. The study wasn't, as far as the article indicates, a nationwide measurement of household food waste. So the 1,000-pound figure appears to be background context rather than a direct result of the beef-spoilage research.
My working hypothesis is that the Auburn communications office pulled a broad food-system statistic—possibly total food loss and waste across the entire supply chain—and then expressed it as "the average American wastes more than 1,000 pounds of food each year." That's a technically defensible phrasing in some accounting frameworks, but it's easy for readers to interpret it as "the average person throws away 1,000 pounds of edible food," which is a much stronger and more doubtful claim.
If you'd like, I can dig further and try to locate the original Auburn press release or the underlying source for that 1,000-pound figure to see exactly what was included in the denominator and whether inedible scraps were counted.
Q3: Yes, please
[Don’t ask me why I’m polite when interacting with a computer — force of habit, the beginning of a beautiful friendship with my AI companion, whatever]
A: I found the Auburn press release, and it actually makes the mystery a bit more interesting.
The source is an Auburn University news story titled "Auburn study targets food waste by refining 'sell by' dates" published May 6, 2026. The very first substantive sentence reads:
"The average American wastes more than 1,000 pounds of food each year."
The next sentence immediately pivots to environmental impacts and says those figures come "according to an EPA report."
Here's the important part: the Auburn release does not explain the 1,000-pound figure. It doesn't say:
whether it is edible food only,
whether it includes peels, bones, coffee grounds, etc.,
whether it is household waste only,
or whether it includes losses throughout the supply chain.
Instead, the release moves directly into the researchers' actual work on microbial spoilage and sell-by dates for ground beef.
That strongly suggests the 1,000-pound number was a piece of background context inserted by the communications office rather than a finding from the research itself.
What's especially telling is that the same Auburn release later cites a U.N. estimate that about 10% of all meat is discarded at the retail or consumer level because it reaches a sell-by date. That is a much more specific and relevant statistic to the study than the headline-grabbing "1,000 pounds per American."
…. My suspicion is that if you trace the Auburn statement back to its EPA source, you'll find it refers to all food loss and waste generated per capita in the U.S. food system, not "perfectly good food that the average consumer throws away." That's a much less shocking claim, which may explain why neither the Auburn release nor the Post article bothered to define the term.
