A notice was published on Portuguese Republic Diary, by DGAV, presenting the approval of the specifications to the production and marketing of pig meat with the label “Porco PT”.
This notice also designates which pig meat is approved to use this reference: meat derived from pig carcasses obtained from animals raised on Portuguese livestock farms, fed on cereals, with certified animal welfare standards. 

The characteristics of the product are essentially due to the feed supplied to the animals, with a minimum of 50% of cereals, to animal welfare conditions, with a fattening area useful at least higher than those dictated by European standards, and surgical castration of the piglets to avoid the odour in the meat. 
The product is placed on the market in the form of carcasses and half-carcases, as well as in the form of any piece of cutting, packed or in bulk.
