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.

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.
