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...

Won't that affect Walmarts profits? 🙃

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

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.
