Where can I buy olive oil I trust?

We've had a lot of friends write to ask us about sources for olive oil that is authentic and not rancid.  The 60 minutes expose of fraud in the industry that aired Sunday night (1/3/16) certainly has consumers worried.  http://www.cbsnews.com/news/60-minutes-overtime-how-to-buy-olive-oil/

I've copied here a response to one friend that might be useful to others who want to know more:

"Yes, it is true that bad, leftover, rancid and leftover oil from the Mediterranean is often dumped in the US where it is thought consumers won’t know any better.

Here is a website from Tom Mueller, author of Extra Virginity,  that documents the best and worst of oils available in the US.  I trust Tom. http://extravirginity.com/2012/09/toms-supermarket-picks-quality-oils-good-prices "
