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.

This sounds like it would be really useful for people with diminished senses of smell

Yes, it's an eco friendly carbon based compound.

You believe that?

Edit: Oh, of course you do haha, and we both know why.

Please feel free to provide your peer reviewed studies on the health hazards.

Please feel free to believe everything you read. Also, it’s their job to provide peer reviewed studies that their product has no health hazards (your words) and is biodegradable (my word).

Have you tried using your eyeholes?

Meat spoilage is not always obvious. A piece of meat can look fresh and firm inside a sealed package, yet still harbor microorganisms that make it unsafe to eat.

Literally the first line of the article

And before people ask about sniffing it, the second paragraph:

People often recognize spoiled meat through a characteristic rotting odor caused by chemical compounds called biogenic amines or BAs. Food quality inspectors quantify these compounds using procedures that involve direct meat sampling and time-consuming laboratory analysis. However, once meat is sealed and distributed for commercial retail, such testing becomes impractical, making spoilage difficult to detect.

You can't sniff it through the packaging. Even when opened, your nose isn't accurate enough to know if something has just started to spoil, or if only a little bit of it has. And not everyone has good (or any) sense of smell.
