Second seizure on the same Köşk road: 4,000 litres of adulterated olive oil, 36 days after 5,300 litres
On 13 November 2026 gendarmes in Köşk, Aydın seized 4,000 litres of counterfeit and adulterated olive oil from a vehicle stopped on the Aydın-Denizli highway; two people face proceedings. On 8 October the same road yielded 5,300 litres: 9,300 litres across the two seizures.
On 13 November 2026, gendarmes in Köşk, a district of Aydın, seized 4,000 litres of counterfeit and adulterated olive oil from a vehicle they stopped on the Aydın-Denizli highway. Teams from the Köşk District Gendarmerie Command, part of the Aydın Provincial Gendarmerie Command, carried out the operation. The two men in the vehicle, identified as A.Y. (43) and M.Ü. (46), were apprehended, and criminal and administrative proceedings were opened against both. The statement as reported says the oil was harmful to health and ready to be put on the market.
What the statement says, and what it leaves out
| Item | Stated |

| Date | 13 November 2026 |

| Nature of the oil | counterfeit / adulterated |
The statement does not say what the oil had been mixed with, what kind of vehicle carried it, what value was put on the load, or how large the administrative fine will be. The calculations below rest only on the stated 4,000 litres and on this site's own price measurements; we do not fill the gaps with guesses.
The same road, a second seizure
This is the second large seizure in a short time on Köşk's stretch of the Aydın-Denizli road. On 8 October, a van stopped on the same highway was carrying 5,300 litres of counterfeit and adulterated oil. The two events are 36 days apart and add up to 9,300 litres. The suspects' initials differ (M.O. and K.Ş. in October), and no link between the two cases has been announced, so we do not draw one.
There is another way to gauge the scale. According to the Aydın Police Department, five separate operations across the province between 1 and 15 September turned up a combined 4,063 litres of adulterated oil; we wrote up that tally at the time. The 4,000 litres from a single vehicle in Köşk this time equal roughly 98 per cent of that fortnight's total. The two figures come from different agencies and may not have been counted the same way, but they show how large a single consignment can be.
What 4,000 litres is worth
No value has been announced for this case, but the site's own data allows a floor to be drawn. On the Edremit exchange, which reports to the Turkish Union of Chambers and Commodity Exchanges (TOBB), extra virgin olive oil was registered on 13 November at 245.30 lira a kilogram. Taking the density of olive oil as about 0.916 kilograms a litre, that is roughly 225 lira a litre, or about 900,000 lira for 4,000 litres. This is not the value of the adulterated oil; it is what the same volume of genuine extra virgin would fetch wholesale.
At retail, in this site's survey on the morning of 13 November, the cheapest one-litre extra virgin label was 249 lira. An exchange registration is a single data point and not a hard threshold for consumers, but the question for any oil sold as extra virgin well below the wholesale cost is plain: how can genuine oil be produced at that price?
One note on scale: in the 8 October case the authorities valued 5,300 litres at 1.6 million lira, about 302 lira a litre. Applying the same rate to this load would give roughly 1.2 million lira, but that is our assumption; no such value was announced for this case.
Counterfeit and adulterated are not the same thing
The statement uses the two words together, but they are defined separately. Adulteration means mixing in a substance that does not belong to the product, or otherwise spoiling its composition; in olive oil it usually means a cheap seed oil blended into extra virgin. Counterfeiting means selling a product under the name, brand or packaging of another. A load can be both: oil diluted with seed oil and filled into the tin of a well-known brand is adulterated and counterfeit at once. The Köşk statement says "counterfeit/adulterated" without separating the two; only the laboratory result and the indictment will show which applies.
Why Aydın appears so often
Aydın does not turn up in these reports by chance. According to the 2025-2026 season table for provinces on this site, the province is Türkiye's largest olive province, with 439,278 tonnes of olives and 22.4 million bearing trees; 296,027 tonnes of that fruit went to oil. In a province where raw material, pressing capacity and the trade in loose oil are all concentrated, an unlabelled load may find it easier to blend into genuine bulk traffic. Where the load was going and where it came from have not been announced; all that is known is that the road runs toward Denizli, out of the province.
What it means for the reader
The Köşk load was stopped before it reached the market, so it appears that none of this batch got to a consumer. Even so, early in the season, when trade in loose oil and tins is at its busiest, the practical test is the same: avoid loose oil that carries no label, batch number or bottling date, and check whether the brand appears on the ministry's adulteration lists. The methods are explained in more detail in our piece on fraud and adulteration in olive oil; for the latest pattern in the ministry lists, see the 27 October notice.
The outcome of the case is not yet known. When the laboratory finding, the administrative fine and the judicial step are announced, this report will need to be completed with those figures. For now, the verified facts are the date, the place, the volume and the two people named by their initials; everything else in this article is arithmetic on public figures, labelled as such.

Six jailed for taking produce without paying: the grower's most fragile moment is the start of harvest
In Bozdoğan, Aydın, six people who bought olive oil, nuts and livestock from growers and failed to pay were caught in a simultaneous operation across three provinces on 15 September and jailed on 17 September. The method is a familiar one: the first purchase is paid in full, and once trust is established the large purchase is not. In the week harvest begins, growers have three concrete protections.

The Didim District Directorate of Agriculture and Forestry, together with the Aydın Provincial Directorate, has warned growers about the olive fruit fly ahead of the harvest. Growers were asked to check groves regularly, monitor pest density and, if needed, act only with products licensed for olives and at the right time. Fly pressure rising in autumn cuts both yield and oil quality.
