In the world of olive oil, authenticity is everything. Behind every bottle lies a story of land, climate, tradition and trust.
But as global markets grow and supply chains become more complex, protecting that story has never been more challenging (or more necessary!).
This challenge took centre stage at the 7th International Yale Symposium on Olive Oil and Health, held in New Haven (Connecticut), from 4-7 December 2025, where leading experts from academia and industry gathered to explore how innovation can safeguard the value, integrity, and health benefits of olive oil.
Among the participants was our partner Stelios Arhondakis from BioCoS, returning for the fourth consecutive year with a breakthrough that strongly reflects the mission of Watson.
Science in service of trust
Hosted by the Yale University School of Public Health, Environmental Health Sciences, the Symposium has become a global reference point for cutting-edge research and dialogue around olive oil.
Beyond health and nutrition, this year’s discussions highlighted a pressing issue: how to ensure that what reaches consumers is truly what the label promises.
For Watson, this question sits at the heart of its work on food authenticity and traceability. And, at Yale, it found a powerful answer in FieldNA.
Introducing FieldNA: DNA testing where it matters most
During the Symposium, BioCoS showcased FieldNA, an innovative device developed within the Watson project that enables on-site DNA testing of olive oil.
For the first time, DNA analysis (traditionally confined to specialised laboratories) can be performed directly in the field or at the mill.
FieldNA brings molecular authentication closer to producers, inspectors and supply-chain actors, making testing faster, more accessible and more affordable.
By isolating and analysing DNA under real-world conditions, it opens the door to a new level of transparency in olive oil production.
This is not just a technological milestone: it is a shift in mindset. Authenticity checks no longer have to happen far away from where olive oil is made. With FieldNA, the lab comes to the mill.
FieldNA exemplifies what Watson stands for: cutting-edge technology applied where it can make the biggest difference.
By enabling on-site DNA testing, Watson supports producers who value authenticity, empowers regulators with practical tools and reassures consumers that the olive oil they choose is genuine.
As BioCoS demonstrated at Yale, safeguarding olive oil integrity is not only about preventing fraud. It is about preserving health benefits, cultural heritage and consumer trust, from the olive grove to the bottle.
As Watson continues to develop and validate technologies for food traceability and authenticity, one thing is clear: the future of olive oil protection is moving out of the lab and into the hands of those who need it most!
