12 October adulteration list: five of 29 records are olive oil, four with seed oil

The Ministry of Agriculture and Forestry added 29 records to its counterfeit-and-adulteration list dated 12 October 2026. Five of them are olive oil. A separate list, covering products that endanger health, received nine records on the same date; none of those involve olive oil.

The disclosure is published under the Food Public Notice programme run by the ministry's General Directorate of Food and Control. Its legal basis is Article 31 of Law No. 5996 on Veterinary Services, Plant Health, Food and Feed, together with Article 8 of the Regulation on Official Controls of Food and Feed dated 17 December 2011. Every line on the list rests on a completed laboratory analysis, which is why the list is not a collection of allegations but a register of findings that have become final.

What the whole notice looks like

The bulk of this notice sits in meat: most of the seventeen records concern mechanically separated poultry meat found in heat-treated sausages. All five entries in the vegetable-oil group, meanwhile, are olive oil. No other kind of oil appears, which is in itself the point — in the product group most exposed to adulteration, only one product shows up.

Four of the five involve seed oil

Four records describe the classic form of adulteration: seed oil blended into a product sold as extra virgin. The fifth is a quieter kind of fraud, because the liquid in the container is still olive oil — only the grade is not what the label claims. We have explained what separates extra virgin, virgin and riviera in a separate article.

Note that four of the five were being sold under the extra virgin name. Adulteration does not register at the cheapest end of the shelf; it registers under the name of the most expensive grade. The arithmetic is simple: the lower the cost of what goes in and the higher the price of the grade on the label, the wider the gap that becomes profit. That is why the same grade name keeps recurring on this list year after year.

The geography of the five is not a harvest-season pattern either. Both Manisa records come from district centres, while the İstanbul and Bursa entries sit outside the production basin altogether, on the distribution and consumption side. Olive oil adulteration is recorded not only next to the raw material but also where bottling and distribution happen.

The season as a whole: 59 records

Of the 320 records currently published on the list, 59 are olive oil. The oldest notice still on display is dated 16 April 2026, so all 59 belong to this year. The breakdown of findings points in one direction only.

Fifty-four records carry the same finding: seed oil. Olive oil adulteration is not a diversifying field; it is the repetition of a single method.

The packaging pattern is just as one-sided. Of the 39 records that state a volume in the product name, 30 are five-litre containers, one is eighteen litres and one is four litres; only five are one-litre. In other words, what gets recorded is not the glass bottle on the supermarket shelf but the tin sold "straight from the producer". Five records describe the product as unlabelled outright.

The traceability column completes the picture: in 19 of the 59 records the brand field is empty or a dash, and 13 carry no batch or serial number. Among those that do, several hold nothing more than a two-digit figure such as "02" or "012". The latest Antakya record is the exception in this table — its batch number is an eleven-digit decimal code, the kind of reference that allows a product to be traced backwards.

One entry in the 12 October notice deserves separate attention. The product is listed simply as "olive oil", there is no batch number, and the trade name of the business behind it belongs not to an oil producer but to a bakery and catering operation. This is where bulk selling leaks into the record: a product leaving the counter of a business that does not press oil, with no paperwork behind it. If something goes wrong, there is no batch to recall, no bottling plant to hold responsible and no analysis history to consult.

The map shifts towards Manisa

Two of Manisa's three records arrived with this notice; before 12 October the province had a single entry. One of them comes from Akhisar, the centre of Türkiye's table olive production and the basin of the geographically protected Domat olive. Aydın leads the table, which its position as the country's largest olive producer and the concentration of bulk oil trade there largely explains. Most of Hatay's twelve records, meanwhile, came from a single business in September.

The olive oil share from notice to notice

The count has fallen across three notices, but that does not support the conclusion that adulteration is receding. More than half of the 21 records on 23 September belonged to one business; a single enforcement file inflated that notice on its own. And of the thirteen notices published since April, two contain no olive oil record at all.

What this list tracks is the calendar of completed analyses, not the prevalence of fraud in the market. Between an inspection and a record appearing on the list there is a laboratory process, so a cluster in one notice may reflect samples taken months earlier rather than anything that happened that week. The same mechanism explains why one name can appear across four separate notices.

Timing

12 October falls in the week the season's first pressings begin leaving the mills. This is the period when the phrase "new pressing" carries a premium in bulk trade and when buying by the tin or the drum peaks. In a stretch where unlabelled selling looks ordinary, telling an untraceable product apart becomes harder — and this season, with field purchase prices collapsing, access to cheap raw material also becomes easier.

For the buyer the test stays short: avoid bulk oil that carries no label, batch number or filling date, and check whether the brand being bought appears on this list. We set out the methods and what can be examined at home in olive oil fraud and adulteration; and the case where adulterated oil sold above the price of the real thing showed that price alone is no guarantee.
