to tell you that food that "doesn't go off" does go off

[Msplace]

There's labels on food that tell you to use it within a period of time of being open. I was advised those labels didn't matter and if it smells ok it probably is, and they're just designed to make you buy more food more often make money. Don't listen to people who tell you this! This poor advice made me very ill.

That makes sense if it wasn't proper yoghurt. One of those made me feel unwell and it was in date.

This^^

Unless yogurt is visibly mouldy or so old, I don’t really remember how long it’s been there, I eat it regularly.

So many people mistake norovirus for bacterial food poisoning.

A good growth of staph aureus has quite a distinctive aroma. Ignore at your peril!

It really doesn't. Staphylococcus is a pathogenic bacteria so has so smell/taste.

You can't be sure it was the yoghurt made you ill. Could've been something else or just a virus.

I buy big pots of yoghurt and never worry about eating within 3 days.

I consider myself fairly cautious around food safety but have definitely eaten yoghurt that has been open for more than three days. Yoghurt grows visible mould if it goes off - I've had that when the pack had been pierced. I've also once taken some yoghurt out of a large pot and thought there was something funky about it. When I dug down there was a kind of big bubble full of mould. So in my experience it would be difficult to inadvertently eat gone off yoghurt as it would be furry!

I read somewhere that it's rarely the last thing you ate that has made you ill. it's usually the thing before the last meal you ate that did it!
If that makes any sense.
Anyway...what else did you eat that day OP?

Good grief. Common sense tells you, you don't open something and leave it open nearly a week before eating it. Behave

dates are for unopened, air hasn't got to it stuff.

Humus ferments as it's going off, ime. It tastes tingly & the flavour goes... I dunno, slightly bitter?, maybe bitter or sour is the word. I can eat it quite fermented certainly without being ill, but I can't be arsed to eat something high calorie that also tastes bad.

I am the Queen of eating old food. Orange juice months past date, scraping mould off cheese or pasta sauce, milk that smells and slightly clots without being quite cheese yet, etc. AMA... I get flipping noro easily but old food I have a cast iron stomach for.

Do you mean proper yoghurt (Greek/ natural)? Or a flavoured yoghurt pudding?

Proper yoghurt would be fine 5 days in a good fridge.

Chickpeas can kill if they are gone off. Be careful.

You can tell if some good is off by the smell such as raw meat, other high risks foods can be riddled with bacteria but don't smell so smelling isn't reliable for things like cooked meat. Some things may not be noticeable by smell but you will take easily, I've normally found yoghurt tastes bad once off. And if course if you are ill particularly with COVID like symptoms, it wouldn't be wise to rely on smell or taste.

I eat Parmesan WELL past due date. Hasn't killed me yet.

I routinely eat open sour cream after a week plus. Unless it looks bad of course.

Just seen your other thread @Msplace - are you pregnant?

You must have very poor immune system.

I'm sorry but common sense should tell you you don't leave yoghurt open for 5 days.

I have Greek yoghurt open for ages. If there's no mould then all good, certainly never made me ill.

DH should be dead then, he regularly eats opened hummus and greek yoghurt that have been in the fridge for at least 2-3 weeks

Yougart at best unopened a day or two past but other than that I prefer to not risk it.
Most foods I try to be sensible with and use them on or as close as to the use by.
Usually most of them I usually freeze then use.

You never opened up a Petri dish with staph aureus on it and smelled it? It’s quite distinctive when there’s a lot of it. You may not detect it on food that’s not safe to eat, but if there’s a lot of growth, there is odour detectable even by human noses.

Oooh I had that twat when I waa a child and it caused havoc before they realised what it is. Bastard settled in a back of my nose and went for a rodeo around.

Yoghurt has a Use By date, anything after that date you have to be cautious when consuming. I've eaten yoghurt well past that date but I do a smell and taste test - if it went off after 5 days of you opening it that's different to the Best Before date anyway.

If the Best Before date had been exceeded and you ate it after 5 days of opening it, then that combination for that specific yoghurt could have caused it to have gone off. I find fruit yoghurts go fizzy (fermented) and that takes the taste test to detect it.

Sorry Use by, not Best Before!

Goodness, have you never heard of botulism?! Vegetarian food can be lethal.

I’ve often used yoghurt after use by and it’s been fine so it may not have been the yoghurt at all. You can tell it’s off by the taste - like off milk - surely?!
