Bertolli Oil - is it safe to use? (cloudy)?

This week one of our local grocery stores has Bertolli Oil on half price.

I use it all the time. However, when I bought it I noticed a sediment in the bottom of the plastic bottle. As the best before date was 2011 SE 30, I thought it should be OK.

However, when comparing the bottles I purchased with the half of bottle still left at home, I noticed the new bottles were "cloudy." I asked at the store and was told - yes, the bottles on sale were kept below 7 degrees so is cloudy, but will clear when you take it home (not so).

The 2 new bottles are still cloudy.

I tried to find a current site for Bertolli and filled out two customer enquiry forms - which were returned by email as undeliverable. I phoned Bertolli twice (Canada number) and went through the menu items and was cut off when I tried to complete the call. I sent another email to Bertolli and have not received a reply.

SO, my question is: is this safe to use? I don't want to open the bottles and smell the oil, as then won't be able to take it back to the store.

With so many serious issues in the world to-day I hate to worry over this: but most of the larger issues in the world I can't do much about - but can do something about this small problem. Thanks for your time
