Olive oil fraud is not just a story about a disappointing bottle. Misrepresentation can undermine consumer trust, disadvantage honest producers and make it harder to know what you are buying.
Our original article explored corruption in the olive oil industry. The concern remains important, but historical investigations, quality failures, adulteration and today's market should not be collapsed into one alarming statistic. This updated guide follows the sources, adds official Canadian findings and connects newer reporting with practical buying questions.
In his 2007 New Yorker investigation, “Slippery Business,” Tom Mueller described olive oil adulteration and tracing failures, including shipments of other oils documented as olive oil. He also discussed historical examples of deception reaching back to antiquity.
The investigation is valuable background, not a current survey of every producer. Its cases and estimates belong to the dates and circumstances reported.
Read Tom Mueller's “Slippery Business.” For the broader cultural story, explore our history of olive oil and Greek tradition.
The Olive Oil Times report cited in our original article discussed Dcoop and Pompeian's OlivExtra Original, a blend whose label listed rapeseed oil and extra virgin olive oil. It reported an 85% rapeseed figure in information provided to distributors, alongside a conflicting claim from unnamed sources that the proportion exceeded 99%.
The report covered concerns about prominent olive oil wording, disputed proportions and criticism of marketing. It also included responses from Dcoop representatives.
That is not equivalent to a regulator establishing that every Dcoop extra virgin olive oil was 99% rapeseed oil. Our original wording overstated the report. A dispute about a labelled blend should not become an accusation against an entire present-day product range.
Read the original Olive Oil Times report and the competing accounts.
CBS's January 2016 “Don't fall victim to olive oil fraud” report examined adulteration and organised crime in the Italian food supply chain. It described both mixing lower-quality olive oils into extra virgin oil and using other oils to imitate olive oil.
The accompanying article attributed a 75–80% estimate to journalist Tom Mueller concerning oil sold in the United States that did not meet legal extra virgin grades. It did not establish that 80% of all current supermarket bottles are non-olive oil, or that every Italian producer is fraudulent.
Failing an extra virgin grade assessment and substitution with seed oil are different findings. The date, definition and sampling basis must stay attached to any percentage.
Watch and read the CBS 60 Minutes Overtime coverage.
In its 2024–2025 Food Fraud Annual Report, the Canadian Food Inspection Agency reported 28 unsatisfactory olive oil samples out of 85 tested through targeted inspectorate sampling, or 33%.
This programme targets higher-risk areas. CFIA explicitly says the results do not represent overall compliance in the Canadian marketplace. They do not mean one in three Canadian bottles is fake.
The report also states that 7,245 litres of adulterated olive oil were prevented from being sold in Canada during that reporting period. That is documented enforcement, not a reason to assume that every failure was ignored.
CFIA reported 11 unsatisfactory olive oil samples out of 66 in 2022–2023 and 22 out of 92 in 2023–2024. Those separate programmes cannot be used to conclude that market-wide fraud increased from 17% to 24% to 33%. Targeting and sampling design change.
Read the 2022–2023 report and 2023–2024 report. Laboratory assessments and label-verification results should also remain separate datasets.
We participated in CFIA testing in 2019 and provided samples of our Original Blend Greek Extra Virgin Olive Oil. Our sample was assessed as “Satisfactory,” while other laboratory jobs in the historical records were assessed as “Unsatisfactory.” This was a result for the sample tested, not an ongoing government endorsement of every product or harvest.
CFIA has continued testing in subsequent years and publishing its findings. The annual reports above explain the more recent results and the limits of targeted sampling. Read our CFIA testing story for more background.
Investigative television and documentary-style reporting can show what happens on farms and in supply chains. The following newer videos broaden the picture. They are not interchangeable with laboratory studies or proof of adulteration in a particular bottle.
This report follows Spanish farmers dealing with olive theft after drought-related harvest pressures. It explores crime affecting the crop and producers' livelihoods, rather than testing retail bottles for adulteration.

This video looks at farmers in Pakistan turning to olive cultivation as climate conditions change. It provides context about new production regions, not an allegation that oil from a particular country is fraudulent.
Watch DW's report on olive growing in Pakistan.
This newer video examines growing olives in places once considered too cold and research into more resilient varieties. It adds context about the changing geography of olive farming and pressure on Mediterranean production.

These are verified video-report pages, not a claim that each is a feature-length fraud documentary. Availability may change. Keep their subject and publication date in view alongside the older CBS investigation.
Authenticity asks whether the oil matches its represented identity. Extra virgin grade involves quality assessment. A phenolic report describes particular compounds measured in a sample. A high number alone does not establish all three.
For a high-phenolic claim, ask which lot, laboratory, test date, method, compounds and units the report covers. A certificate from another harvest needs an explanation before it is used to describe current stock.
Explore Polyphenols, Testing, and Trust and our polyphenols introduction. Composition research is not a promise that an oil prevents or treats disease.
Our authentic EVOO buying guide and olive oil storage guide expand on those questions.
A large company is not automatically dishonest, and a small farm is not automatically verified. Country, size and price are not substitutes for evidence. Responsible producers of different sizes deserve to be assessed on what they can substantiate.
At Ilias and Sons, our Greek family connection is central to the product story. Gourmet Greek Organic Extra Virgin Olive Oil, Original Blend combines Athinolia and Koroneiki olives with a fruity, grassy profile and a milder peppery finish.
7Thirty high-phenolic organic Greek extra virgin olive oil offers bold, peppery early-harvest Koroneiki character. Visit our 7Thirty education page for more context, and ask about evidence specific to the product and harvest you are considering.
Our La Bottega and Edible Ottawa tasting story reflects the value of meeting the people supplying your oil. That tasting collaboration was separate from CFIA testing.
We also value our retail partnerships with Misto Fine Foods, B&H Grocery and Foodsmiths. Visit Where to Find Us and check each store's current selection.
Olive oil fraud merits scrutiny. The strongest response is dated, traceable evidence and better explanations, not a claim that every supermarket bottle or industrial producer is corrupt.
Read the original investigations, understand the official sampling findings, and ask questions about the oil in front of you. Honest producers and consumers benefit from the same thing: a product story that can stand up to examination.
