Slaughter condemnation in bovine due to parasitic lesions and their economic impact in Federal Inspection System establishments in Brazil and in State inspection System in Rio Grande do Sul State

Abstract

Slaughter condemnations are important sources of information on cattle health. The incidence of bovine parasitic diseases is still very high in Brazil. These diseases, in addition to causing harm to the animals health, are neglected zoonotic diseases in several parts of world. The study analysed not only the Carcass losses, but also the economic damage resulting from slaughter condemnations due to parasitic causes. Cattle slaughter data from the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA), over the period of 2012 to 2015 and data from the Secretary of Livestock and Irrigation of the state of Rio Grande do Sul (SEAPI-RS) were analyzed between 2014 and 2018.The number of organs and carcasses condemned was multiplied by the respective values (in Brazilian Real) obtained from slaughterhouses and subsequently converted into dollars. Brazilian analysis in SIF (Federal Inspection System) establishments showed that more than 1.2 million organs (3,884,505 kg) and 20,000 carcasses (4,547,718 kg) were condemned only due to parasitic causes during post-mortem inspection. In Rio Grande do Sul, in state inspection establishments, more than 1.7 million organs (8,210,559 kg) and 5,000 carcasses (1,243,200 kg) were condemned. These data are alarming and support the need for public policies to control these parasitic diseases.

Main causes of cattle slaughter condemnation under the state sanitary inspection in Bahia, Brazil

“…However, different causes of carcass and organ condemnation can show higher condemnation rates depending on the region of the country, the sanitary inspection and the technology used for animal husbandry and handling. Cysticercosis, hydatidosis, and tuberculosis are the important causes of condemnation of cattle slaughter in the states Rio Grande do Sul (Bica et al, 2018;Bem Bidone et al, 2021) and Minas Gerais (Oliveira et al, 2020). According to Silva, Groff, Bassani and Pianho (2016), cachexia was responsible for 24.74% of the total carcass condemnations in one slaughterhouse in Paraná, Brazil.…”
