Do you mean when they are unopened?
I have had yogurt in the back of a cold fridge that was completely fine a couple of years after purchase.
But not things that have been opened – ricotta and cottage cheese are particularly prone to early spoilage.
I am talking only about products with no additives.
Milk lasts long past the date when transferred to glass bottles. Left in cardboard, it spoils up to a week earlier.
That’s it. Thanks!
What do you mean when you write “tested”? About two weeks ago I ate some month old chili oil that my daughter made with garlic andI didn’t appear to get botulism. Tested like that?
Mostly a test of love for my daughter. I just couldn’t bear to toss it without trying it.
My friend and her husband gave me chimichurri with parsley, oil and garlic in it, that they kept at room temp, for xmas one year. Not sealed, just in a plastic dish with plastic wrap on top. Not a chance I was trying that. I kept the plastic dish. 
The glass bottles seem to keep milk fresher, longer. I’ve been able to buy milk in glass bottles for a few years now, and the flavour is better, as well. That could, of course, be due to the fact that it’s from a smaller, local herd of cows.
That’s happened to me, and the cream wasn’t even past the sell-by date.
Yep, that is indeed what I meant.
@Saregama - agree re opened v unopened. Ricotta opened seems quite prone to pink mold (Aspergillus, I think it is).
@Phoenikia - yeah, ageee, one daughter is on monthly biologic immunosuppressive injections. I don’t take chances with her.
We have noticed that milk from our regular grocery store (I do probably 90% of my shopping there) will rarely make it to the pull date before going off. Contrast that with the closer but more expensive grocery store, whose milk will regularly last three weeks past the pull date, sometimes a little more. I think it’s the way the two stores handle the milk. I’ve seen how my regular store just stacks stuff in the aisles to be stocked, and that includes frozen and perishable items. There’s no telling how long that stuff sits before getting put away, and I wouldn’t be surprised if they have pallets of milk sitting in room temperature storage for a few hours until a stock clerk can get to it.
I just bought a couple of cartons of Prairie Farms UHT tetra pack whole milk. TBH I don’t think I’ve had a glass of milk in 30 years. So this was a cooking stash. Curiosity got the best of me, so I put a carton in the fridge (which I keep as cold as possible). I opened it and poured myself a juice glass full. I was expecting it to taste like evaporated milk, or powdered milk. I was pleasantly surprised - it wasn’t bad at all. Probably because it was full fat. Don’t know how long it keeps in the fridge after opening. I expect it wouldn’t be any different from fresh milk in that regard.
I buy and drink raw milk, and quickly learned to transfer it to a glass bottle. Wasting that stuff is hard.
I forgot some cracked green olives and garlic marinated olives from the olive bar were in my bag of groceries in my car
They aren’t full submerged in the brine.
They have been at room temperature or slightly cooler for 48 h. Do you think they are safe to eat?
I don’t have a good answer, but I bet it has to do with individual risk factors. Like what is the most likely pathogen in that scenario (IDK), and does that pose a particular risk to you.
“When in doubt…”
At room temperature brines can be good breeding ground for bacteria. If it is left out for two days I would throw it away
I would eat it, as I seem to have intestines and internal plumbing made of adamantium reinforced with Vibranium.
But I would never ever tell someone else to do the same thing.
Or how badly you want a legitimate reason to call in sick to work the next day
Sorry, yes I meant to reply unopened dairy stuff many months after “best by”. And also I’ve noticed that smashing cling film down atop opened dairy (like ricotta that I only use once a week) to cover the entire surface avoids the mold. Same for opened cans of tomato paste. I don’t need this for any yog or sour cream products because they get used so fast here.
I store the dairy container for yogurt and cottage cheese upside down in the fridge. Been successful for many years.
Thanks. Do you mean after opening, you put them USD, and this helps?
