More on olive oil

There was a piece in last week's New Yorker about the "adulterated" olive oil industry that was pretty interesting. I think a lot of people assume there's some question as to the purity of product in an industry like this. Here's some proof for the skeptics:

...Investigators discovered that seed and hazelnut oil had reached Riolio’s refinery by tanker truck and by train, as well as by ship, and they found stocks of hazelnut oil waiting in Rotterdam for delivery to Riolio and other olive-oil companies.

The investigators also discovered where Ribatti’s adulterated oil had gone: to some of the largest producers of Italian olive oil, among them Nestlé, Unilever, Bertolli, and Oleifici Fasanesi, who sold it to consumers as olive oil, and collected about twelve million dollars in E.U. subsidies intended to support the olive-oil industry. (These companies claimed that they had been swindled by Ribatti, and prosecutors were unable to prove complicity on their part.)

And this...

In February, 2006, federal marshals seized about sixty-one thousand litres of what was supposedly extra-virgin olive oil and twenty-six thousand litres of a lower-grade olive oil from a New Jersey warehouse. Some of the oil, which consisted almost entirely of soybean oil, was destined for a company called Krinos Foods, a member of the North American Olive Oil Association.
