              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.

      Sure, but only if it instead gives people a type of incurable cancer in about 30 years.

    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

    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.

        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’ve got a fairly reliable tool that does the same, I keep it in the middle of my face

    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…

    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.

      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.

      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.
