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.

Average Americans will never see this. This comes at a time when regulations are being removed and meat packers are shooting up beef with red die to make it not look bad and rotten fish is being treated with CO and dies to be sold as fresh fish…
I’ve got a fairly reliable tool that does the same, I keep it in the middle of my face
Anosmia is more common than you might think. A lot of stuff that seems silly on the face of it is hella useful for people with disabilities.
Noses do seem silly on the face of anosmics.
I really walked into that one huh
Sure smells like it!
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
After they are legally mandated to use it because selling spoiled meat is profitable.
Cool cool.
leans forward
Now, can it also not persist in the environment for 1000 years after the thing it was packaging has been unpackaged?
Sure, but only if it instead gives people a type of incurable cancer in about 30 years.
The Dow is over 50,000
But what does the scouter say about his power level, Vegeta?
leans forwarder
Huh Vegeta?! What’s it say!?
Someone AI a gif of this STAT
No. Here’s a memegen though?
I’m sorry faceless downvoters, my bad. My morality was compromised.
AI is terrible and everyone hates it because they exploit a large database of unlicensed copyrighted works to generate images for profit
Memegen site images are a better because they exploit a large database of unlicensed copyrighted works to generate images for profit but have been doing it for longer, so it’s fine.
haha thats the new fresh thoughtterminating sequence i love it
Won’t that affect Walmarts profits? 🙃
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 🚀
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

Average. 13.99/lb.
That day. 22.99lb.
Understand it just fine.
Thank you come again!

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.
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.
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.
No matter where you buy it, expiration dates are only a general guide, and more of a “date of manufacture” note than anything. We evolved to detect potential food that has gone bad. Trust your senses. Look and smell should be enough to know what’s actually gone bad (which is usually past the “expiration” date). You can use something like this as a better guide for when food will actually go bad, but, again, trust your senses.
Where the hell are you buying meat? A friggin’ flea market? BS.
I was buying it at Kroger, but got tired of meat being expired the first day I got it home, long before the expiration date. Now I buy from a rancher down the road. Re-reading my comment, it may have been unclear that I’m buying local to get better quality than I can get from big corporations.
I have an extremely simple solution for this made-up problem : Just don’t eat meat 🤷🏻♀️
What are you, a tiger ? No ? Then why do you put yourself through this, when it only makes you sicker the more you do it ?
Humans are not herbivores. There are a lot of good social and ethical reasons to not eat meat, this is not one of them.
Humans may not be obligate herbivores ; nonetheless eating meat invariably hurts us in the short and long term.
Meet is like alcohol, you can get your calories from booze ; but why would you inflict that upon yourself ?
Eating meat is only deleterious. You may be able to stave off the visible consequences for a while, but make no mistake, it is eating you from the inside.
We were not meant to feed upon murder.
Proof ? Vegans are the only human group to be consistently healthy and long lived. We are exempt from many illnesses considered nigh-inevitable, even when genetically predisposed.
Vitamin B12 has entered the chat.
Oh. Okay. So maybe I’ll eat nothing but broccoli and pears.
I envy your ability to speak so confidently from a point of ignorance.
there is no way you are a real person. Troll harder.
lots of extraordinary claims here, but no proof at all
Bold of you to assume I’m not happily getting plenty of calories from alcohol, especially the past 15ish months
Shut up.
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.
Freeze your mom, freeze your dad!
Freeze your recent high school grad!
Freeze the dog, freeze the cat!
Freeze your hurble durble sprat!Freeze it all or freeze it none,
If it’s frozen you have won;
Freezing everything you see
Will grant you immortality!This is why I can! I don’t have enough freezer space!
I live in an apartment with a very small fridge that has a tiny freezer inside it. I got a small chest freezer that I use for storage. I only use the one in my fridge for freezing stuff, then it moves to the chest freezer.
Do you do meal planning and if so do your plans include your frozen stuff?
When I have energy I sometimes make ravioli or lasagna and freeze it! But it requires energy and 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.
