Food safety consumer concern is increasing, which led to the implementation of stricter hygiene rules which are applicable to animal products. In this scenario, slaughterhouses and sanitary inspection plays a critical role, since they allow to identify and minimize the specific hazards for human health. Through the assurance of animal well-being and through the ante and post-mortem inspection, it is possible to guarantee that products of animal origin reach the consumer in a safe way. Mainly goals of this thesis were the classification and quantification of the animal origin by-products obtained during health inspection and slaughter operations, as well as the assessment of the economic impact of these products for the slaughterhouse. A record was made for the weights of the by-products obtained monthly through the slaughtered species in Mafra´s Regional Slaughterhouse, bovine, equine, ovine and caprine, during the internship period from February to July 2015. During this period, it was possible to determine that, from the by-products produced over these months, more than 50% were of category 3 by-products. The amount of category 1 by-products produced varied between 31 000 kg and 45 000 kg, the amount of category 2 by-products varied between 28 000 kg and 36 000 kg and the amount of category 3 by-products varied between 67 000 kg and 86 000 kg. Economically, despite of animal origin by-products being considered just a “complementary” service, the income of category 3 by-products generates a value of 41 709 € which covers the cost associated with the elimination of category 1 and 2 by-products (37 517 €).
