I honestly don’t really pay any attention to expiration dates on dairy products. I rely on my keen sense of smell. The smell of any type of spoiled sour
dairy is unmistakable.
I drink milk so fast and so often that it almost never spoils before I finish it.
And I’ve never had a bad container of Yogurt. I tend to stock up big time when my favorite brand (Brown Cow) goes on sale so I can have it sitting in the fridge for 6 months or more.
And my favorite brand os Sour Cream usually only goes on sale for 99 cents per container once a year in the Fall at Meijers. But Breakstones seals their containers really well and as long as it’s not broken, it’s fine for close to a year. A few days ago I cleaned out the fridge and found a few containers from last Sept.
The seals were intact and it tasted just fine, delicious as usual. I used up one whole container with absolutely no ill effects and I still have a couple
more left.
There was one time a few years ago when there was one container with a loose seal. It smelled ok but I took just a tiny bit on the end of the spoon to taste. It was unusually bitter so in the garbage it went.
Spoiled dairy is pretty much impossible to eat or drink cuz you just can’t get past the smell or the taste. So, I’m not worried about it.
I’m much more concerned with not buying canned food with significant dents (which can possibly weaken the metal) because Botulism is a whole lot more deadly.
The typical result of drinking slightly spoiled milk is diarrhea, not death.
