The North American Olive Oil Association (NAOOA) conducts the nation's largest and most complete olive oil testing and certification program. We purchase olive oil from supermarkets in the USA and Canada and test multiple times per year for adherence to the standards set by the International Olive Council (IOC). The olive oils listed below are certified by the North American Olive Oil Association for both purity and quality. Look for our About Olive Oil.Org quality seal when shopping for olive oils.

How does the AboutOliveOil.org Seal Program work?
Participants in the AboutOliveOil.org Seal Program must agree to have us randomly test their products, which we sample from store shelves, and submit the samples to certified independent laboratories. The oils are tested to ensure that they meet or exceed the standards set by the International Olive Council. Participants pay a fee to participate in the program and license the AboutOliveOil.org Seal for use on their packaging. It does not mean that we test every bottle or even every lot. However, the penalty for getting caught is severe. If we can confirm that a product we have tested is not authentic, the company is required to conduct a recall of the licensed products from all stores across North America.
Do you test all brands?
No. We only test bottles of companies that agree to take part in the program. The program is currently only open to members of the North American Olive Oil Association.
Does the fact that an olive oil does not have your seal mean that the olive oil is not authentic?
The answer is emphatically no, for a number of reasons. First, we only test bottles of companies that agree to take part in the program and pay the licensing fee.
More importantly, notwithstanding what you may have read elsewhere, scientists from the FDA have concluded in a study published in 2015 that the risk of purchasing a bottle of adulterated EVOO is low (less than 5%). The scientists randomly sampled 88 bottles of EVOO that they purchased from supermarkets and online stores, and did not find a single instance of adulteration. This may not be what you read on the internet (even from sources you may otherwise believe to be reliable), but you have to ask yourself whether you are more comfortable believing a published report from FDA scientists, or some journalist that is trying to sell a story. We invite you to read more stories related to olive oil quality on our blog.
So even if a product does not have a certification seal, you should feel confident you are getting authentic products, especially if you buy from a retailer that you trust, select a brand that you know, and/or do not pay a price that is “too-good-to-be-true.”
The brand I usually buy does not have your seal…when will you test it?
We only test brands that agree to be part of our program. Please inquire with the brand and suggest that they might join.
I just purchased a bottle from a company whose name is listed on your webpage of certified brands, but the bottle does not have the seal on the label. Does that mean it is not authentic?
No. There are a couple of reasons why this may be the case. The AboutOliveOil.org Quality Seal program is product specific—not company specific. Companies have to pay the fee for each specific product. A company might agree to pay the fee for their best-selling item, e.g., “Premium EVOO,” but not for a product that does not have wide distribution or high sales, e.g. “Organic Limited Edition EVOO.”
Also, it is important to know that companies in the program are not required to put the AboutOliveOil.org seal on their labels. Many are content just to have the seal listed on the website, because labels get crowded and they may wish to use the space for other information. So it is possible that it is the case with the products you have purchased.
