Our friends at Olio2Go.com were quoted in the Washington Post on the subject of food fraud. It's a very interesting article and we urge you to give it a read.

I read the article and I am not surprised; I have heard that in the state of Kansas that is becoming a common event from the Soybean people... no evidence, just heard. I use olive oil without the virgin label, because I wanted to get the most from my olive oil. What I have found is only rumor.... but like a fairytale, rumor is sometimes founded in truth.
Interesting read, thanks for bringing it to our attention.
