Is olive oil ok when it's all cloudy at the bottom of the bottle?

[99redballoons]

I have some mild olive oil from sainsburys', brand new and just realised it's got cloudy bits in the bottom. It doesn't shake in. I have since been to Sains, but forgot to take it back, and checked the others on the shelves and they all have this in them.

Is it ok to use like this? Thanks.

it's usually only cloudy if it's cold

I deliberately seek out the cloudy ones.

ahh! ok. Didn't realise. That makes sense. Will see what happens to it in my cupboard then!
