The Consortium of the Prosciutto San Daniele DOP has recently introduced some modifies of the production rules towards a further high quality product and food safety, based on scientific data. Among the main measures are: the limitation of the production crosses with the consequent institution of a genetic database in order to guarantee the effective truthfulness of the genetic characteristic of the pigs admitted to the PDO, the more strict nourishment rules through an high use of noble cereals, the minimum aging extended to 400 days and the lowering of the salt content.
