Combatting Olive Oil Fraud with DNA Technology in Italy
Rome, Tuesday, 18 November 2025.
European experts use portable DNA kits in Italy to fight olive oil fraud, enhancing transparency and consumer trust as food fraud becomes increasingly sophisticated.
The Growing Problem of Olive Oil Fraud
Olive oil has become one of the most adulterated food products, making it a prime target for fraudulent practices. As demand for this staple of Mediterranean cuisine grows, so does the potential for unscrupulous producers to dilute pure olive oil with cheaper oils, deceiving consumers and undermining genuine producers [1]. This problem is particularly acute in Italy, a leading producer of olive oil, where maintaining the integrity of this product is crucial for both economic and cultural reasons [1].
Introduction of DNA Testing Technology
In response to the increasing sophistication of food fraud, European experts are introducing an innovative solution: portable DNA testing kits. Developed by the Greek biotech company BioCoS, the Field DNA device allows for on-site DNA testing, making it possible to verify the authenticity of olive oil directly in the field [1]. This technology represents a significant advancement over traditional laboratory testing, which can be time-consuming and costly [1].
How DNA Testing Enhances Authenticity
The DNA testing process involves isolating and analyzing the genetic material of olives to confirm their variety and origin. This method ensures that the oil in question truly originates from the olives it claims to, providing a level of assurance that is not possible through chemical testing alone [1]. This innovation is part of the broader Watson Project, funded by the Horizon Europe programme, which aims to enhance food safety and authenticity across Europe by leveraging cutting-edge biotechnology [1].
Impact on Producers and Consumers
For producers like Antonella Meyer-Masciulli, who focuses on olive oils from ancient trees in Amelia, Umbria, this technology offers a way to authenticate their products and protect their brand’s integrity [1]. The DNA testing kits give each bottle of olive oil a ‘digital passport’, accessible via a QR code, that traces the oil’s journey from field to bottle. This transparency helps build consumer trust and allows them to make informed purchasing decisions [1].
