Summary:
The law about the Quality Standard for Iberian pig products (RD 1469/2007 from November 2)
establishes a requirement Iberian pure maternal origin for products sold as "from Iberian" within the
Standard. Because of the maternal inheritance of mitochondrial DNA (mtDNA), its study and analysis
is an useful tool in combination with other molecular tools to ensure regulatory compliance. The
complete sequencing of the mtDNA from Iberian, Duroc, Large White and Mangalitza pigs allowed
identifying 199 type SNP polymorphisms located in the mitochondrial genome. These results belong to
a wider genomic development for the analysis and fingerprinting of the Iberian pig and its products.
