Mayo left out overnight keep or throw away?

[SunshineOverStress]

So the mayo was left out overnight, a brand new bottle which had been used once! It’s been warm out and I’ve only just noticed it, is it safe to keep or does it need to be thrown?!

[Branster]

Throw it away!

[dementedpixie]

It'll be fine. I assume you mean a bog standard shop bought mayo?

[Branster]

Rule of thumb with food: if in doubt, don’t.

[Pipandmum]

As mayo is stored in the cupboard for ages before opening I wouldn't worry.

[nokidshere]

I'd just put it back in the fridge and keep it

[GreenOliveTree]

Yeah we don't keep mayo in the fridge anyway so I'd keep it 🤷🏼‍♀️

[Elouera]

Does it contain egg, or is it just oil?

[ScarfLadysBag]

I'd keep it. This happens in our house more than I care to reveal and it's always fine

[Sunshineonacloudyday20]

Listeria - throw away!

[isabellerossignol]

I'd throw it away if it was homemade. If it's shop bought I'd stick it in the grid and think no more of it.

[Whatifitallgoesright]

Of course don't throw it away! Just stick it back in the fridge.

[isabellerossignol]

The grid? The fridge.

[Foggymist]

It's fine! Unless it's homemade? If it's bought ot's completely processed, one night at room temp wouldn't make a bit of difference.

[Foggymist]

*it's

[Ultrasoft]

I'd definitely keep it.

[Calic0]

If it’s shop bought mayo it probably has a fair few preservatives and what have yous stuffed in there - it’s not just egg yolks and oil. Unless it smells dodgy then I’d keep it. But I’ll admit that compared to some here on MN I am rather lax about food hygiene (late 30s and never had food poisoning though...)

[fuckyouSaul]

Eh????

Sometimes MN is so far removed from reality it's untrue

[Destroyedpeople]

If it's shop bought keep it. If home made chuck.

[fuckyouSaul]

Where is mayo in shops?
On the shelf. For ages. My mind is truly boggled with this one

[ScarfLadysBag]

Throwing it away would be a ridiculous waste!

[thepeopleversuswork]

Technically you should probably throw it away due to listeria risk but I have to say I've done this dozens of times and not once got ill.

Shop-bought mayonnaise is full of preservatives. If Its home made I wouldn't risk it.

[dementedpixie]

Its pasteurised egg with oil and vinegar. It'll be fine

[mummabubs]

We often forget to ours back in the fridge until the next day and never had any negative effects of that! :)

[CuriousaboutSamphire]

Good grief!

Homemade and yes, throwing it away would make sense.

But shop bought? Stick it in the fridge and don't give it another thought!

[YinMnBlue]

Shop bought: fine.
It's pasteurised.
Full of oil and salt - both good preservatives.
And, anyway, it's fine.
