It's not "adulteration" so much as fraud by mixing it with cheaper oils or labeling oil as "extra-virgin" when it's not.

That's what "adulteration" means. From the study I referenced:

"Three of the 88 samples labeled as EVOO failed to meet purity criteria, indicating possible adulteration with commodity oil and/or solvent-extracted olive oil."

3 out of 88 is not that bad. If you read this thread everyone is thinking most EVOO is adultered. If you buy from a trustworthy company, you would most likely be ok.

We only use OO in our house and almost all of it from Cosco.. Refined + 15% EV for cooking and Organic cold press EV for salads and cold dishes.
