Quark? Quack?

Can I eat this filter > Unopened, refrigerated package of yoghurt. Expiration date was a week ago. Safe or not?

As mentioned above, I have a package of 500g Quark cheese/yoghurt (Dutch product, tastes like yoghurt rather than a soft cheese), it's been in the fridge since I got it and I haven't opened it yet, though the date of expiration is the 24th of October. Can I eat it or should I trash it?

If it were me, I would judge by smell. Trust your body.
Or, you can do better still by just throwing it out. Yeah, if it were me, actually, I would probably just do that.

Unless it smelled bad, I'd eat it.

Dairy products don't go bad nearly as often as they just turn into other dairy products.

It is definitely not worth it to eat it. I'd toss it.

I'd eat it, unless it smelled or looked off. Especially a relatively robust product like Quark.

Okay, so I opened it (looks fine), smelled it (smells fine) and tasted a bit of it and it tastes like sour cream or something close to that. Did I poison myself? That is to say, it tasted good, but not like what I expected.

I add that I come from a dumpster-diving subculture and have seen a lot of food on the cusp of going bad - if it hasn't been opened, has been refrigerated, tastes and looks okay and is comparatively close to the sell-by date, in my experience it is more than likely fine. Now, if it has been sitting out in a dumpster in the summer sun for even a few hours, you should definitely throw it away!

In my life, I've learned that expiration dates on dairy products have to assume that people are pants on head stupid and haven't had a problem exceeding them. I smell things first, of course.

I think you are entirely too worked up about it and shouldn't eat it if just because you'll be analyzing your every stomach gurgle. :)

It's a sell by date, bit an eat by date. You're fine.

I tend to go on the principle that "is [milk product] off?" is a question like "did my bike just develop a puncture?" or "am I in love?". That is, if you have to ask the question, the answer's no. When milk's rancid, there's no two ways about it.

This goes double for yoghurt, which is meant to be "off": that's why it's yoghurt, not milk :-).

Hi. I work in the commercial yogurt industry. The yogurt is fine to eat unless you see yeast (usually shows as pinkish) or mold (green, black, ect) on it.

It has already fermented, so unless there is mold or something else growing on it, it is fine to eat.

The nose knows.

I have eaten expired yogurt many times and am fine. However, if I had myself convinced something might have gone off, I wouldn't enjoy it and my tummy might feel weird afterwards.

I buy refrigerated sealed cartons of yoghurt and leave them unrefrigerated for a week or two so that they will develop a more sour flavour. I don't even look to see if they've passed their expiry dates. Once opened, I refrigerate. This works very well for me.

Oh, hell yes, eat it. Yogurt is fairly rotted to start with, so what's the harm?
posted by BostonTerrier at 5:24 PM on November 2, 2012


You can eat it. If it it does not have either pink slim or green/black mold you are fine. The nose is another indicator, if it smells rotten then be concerned. I collect yogurt and have several year old stashes so, yeah, as long as it is refrigerated, sealed and has no other indicators of spoilage then you are good to go.

As a side note, as long as the yogurt does not have the previously mentioned yeast or mold, the only thing that happens over time is that the pH continues to go down and the yogurt tastes more sour. Also, the "live and active cultures" start to die.

Quark cheese/yoghurt (Dutch product, tastes like yoghurt rather than a soft cheese)

This is entirely unclear from the European side of looking at it. Are you eating Yoghurt (in which case I'd totally eat it, following catseatchees'e evaluation), quark (which should taste sour, but not "a bit like sour cream" at all, and so I'd be more hesitant), or (soft) cheese? What consistency are we talking about?

I also have experience in the dairy/yogurt industry, and the expiration date is anywhere around 10 days in advance of it "going bad", as a buffer for sensitive stomaches. As for myself and my family, we eat yogurt that has exceeded the expiration date by up to four weeks without any issues. The texture may be a bit thicker, but it's fine as long as it has been sealed properly and temperature controlled.

Yoghurt stays good for ages. I'd eat it and so would my cat.

Yesterday I found an unopened quart of Cabot full-fat Greek yogurt in my fridge. It still had the seal on it, and the expiry date was Sept. 10. I removed the seal and tasted it - delicious! So I ate it. No problem, two months after the sell-by.

It's still good. There aren't as many live and active cultures left, but it's fine to eat. By the way, Greek yogurt is more sour creamy than non-Greek, juts in case you've never had it.
