Protected designation of origin (PDO), protected geographical indication (PGI) and Traditional Speciality Guaranteed (TSG) are geographical indications (GIs) defined in European Union Law to protect the names of regional foods. The law (enforced within the EU and being gradually expanded internationally via bilateral agreements of the EU with non-EU countries) ensures that only products genuinely originating in that region are allowed in commerce as such. The legislation came into force in 1992. The purpose of the law is to protect the reputation of the regional foods and eliminate the unfair competition and misleading of consumers by non-genuine products, which may be of inferior quality or of different flavor.
