What the hoopla is about is a year or two ago it was found out the Italian mafia kind of had a corner on a lot of the major olive oil market. and they were adulterating it with oil other than olive. There was an independent study that tested a lot of oils and quite an alarming number, even major brands, were not 100% olive oil. Even though the label said they were.

I think that is what Buster50 was referring to.
