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.

    leans forward

    Now, can it also not persist in the environment for 1000 years after the thing it was packaging has been unpackaged?

    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.

    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.

    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!
