Under Council Regulation 2081/92, extra virgin olive oils (EVOOs) with protected origin status (PDO, PGI) will have specific olive cultivars used in their production laid down to achieve registration of their protected origin. This review details the use of microsatellite markers (SSRs- simple sequence repeats) to verify the olive varieties used in the production of EVOOs, and hence authenticate their protected origin status. This is achieved by comparing the molecular SSR profiles of the oil with online molecular databases. In Italy for example, the SSR profiles are processed into an "identity card" that can be converted to a barcode or QR code on the labels or bottle caps, which can be read at any point along the supply chain, even by consumers and inspectors via a mobile phone, to verify the status and authenticity of the EVOO.
