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.

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.
