Scientists designed color-changing carbon dot biosensors that can detect spoiled meat in sealed packages in real-time, just in case you don’t trust the sniff-test.
They’re going to make this way too sensitive so people throw away even more food and effective prices get driven up. I guarantee it
Cool cool.

Now, can it also not persist in the environment for 1000 years after the thing it was packaging has been unpackaged?
The Dow is over 50,000
But what does the scouter say about his power level, Vegeta?

Huh Vegeta?! What’s it say!?
I’ve had a number of occasions where I purchased meat and it was spoiled before the expiration date. At this point, I’m sick of putting my trust in big corporations and am trying to buy more foods produced locally.
Won’t that affect Walmarts profits? 🙃
Pictured is meat with Kirkland branding, which is Costco’s in-house brand. Better place to shop than walmart already
3 Ribeyes are currently $67 there. You cracked out? Lol
Looking at my nearest Costco vs Walmart prices
Ribeye choice:
Costco $15.99 / lb
Walmart $23.47 / lb
Ribeye prime
Costco $20.99 / lb
Walmart $27.98 / lb
I was just at Costco yesterday. Then again different prices in different states?
Costco slices their ribeyes thick. 3 at ~1 pound each is right around that prime price.
Don’t buy at Wallmart
Guy you can’t say that! Won’t you think of the poor CEO?
options here are 1 corporation that owns a castle and got his balls tickled for decades long price fixing
and walmarts… there is no good options to shop for food until they are removed from the planet
until they are removed from the planet
Where can I donate to your campaign?
they have the rockets 🚀
10% off sticker goes brrr
The indicator turns into a “manager’s special”, no need to pay an employee to slap them on anymore
Gross. 🤣
As a negative control, they also prepared an identical sealed tray containing only a wet sponge and the biosensor, but no meat. They observed that the biosensors in the pork and mutton trays turned bright yellow after 24 hours, while the one in the beef tray took 36 hours. In contrast, the control biosensor showed no detectable change.
That’s so cool, meat is still gross, but this is unambiguously a fantastic thing for humanity. If it’s actually used, I’d have to imagine the less reliable yet ass covering legal expiration date sticker will always be cheaper. Hope this becomes the new mandated standard, innovations are meaningless in the face of uncaring capitalism.
All meat is spoiled living animal tissues. Way easier way to figure that out :)
No, actually. Spoiled here refers to the edibility by humans (aka the bacteria and toxic waste of said bacteria is below safe levels), and it’s no longer living tissue given the animal has been killed and butchered.
Do you live on a dump?
These days the whole planet is a dump unfortunately.
If people don’t trust it either, there’s also an alternative, reading the package for the expected spoiling date.
That date means nothing. It’s a best by date, not an expiration date. It’s just the last date you can get a refund if it goes bad.
But I’ve had a gallon of milk last a whole month after the best by date.
Yeah, the date on the package means even less if you freeze it. Frozen meat is good for years.
(Freeze your ground beef, freeze your bread. Throwing away food is expensive!)
Yes, and freeze sauces, soups, and stews in ice cube trays and then into freezer bags for easy portioning later. This was life changing advice for me.
This is why I can! I don’t have enough freezer space!
We use these for soup:

Pricey for glorified ice cube trays, but really convinent to have the soup portioned to size.
The expiry date has been a necessary and useful tool, but these dots seem like they could be a good idea if they can actually sense when spoilage happens.
Meat could have been exposed to bad conditions that makes it spoil before the expected date.
But maybe even bigger is that the date is always going to be very much on the side of caution, so it might avoid waste where people tend to bin stuff as soon as the expiry hits, even though that food may still be perfectly good.
I’ve had Milk that lasts a week longer than the expiration date, and I’ve had meat spoil a week before its use-or-freeze-by date
I’ve had stuff spoil early, or last long past the date. Having a visual chemical indicator would be great.
