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.

Highlights

Brazil, with its 226 million cattle population, has 22.6% of the total cattle worldwide
Nosographic data obtained from slaughterhouses are an important source of information, and economic losses due to condemnations of affected organs and carcasses can be estimated through them (Nif & Alonge, 1987)
The main reasons for condemnations in cattle slaughterhouses are due to lesions associated with cysticercosis (Marques et al, 2008; Dutra et al, 2012), hydatidosis (Cabrera et al, 2002, Tessele et al, 2013) and fasciolosis (Dutra et al, 2010); all of these are parasitic and zoonotic diseases, which are often neglected in the prevention aspect (Molento & Pritsch, 2018)

Summary

Introduction

With its 226 million cattle population, has 22.6% of the total cattle worldwide. Products resulting from the process of slaughtering bovine are called carcasses and by-products; organs are economically important, because they add value to production and are potential sources of nutrients, especially with the increasing world population size and the increasing demand for high quality protein (Kale et al, 2008). In addition to causing decreased performance of animals in vivo, parasitic diseases such as cysticercosis, fasciolosis and hydatidosis cause carcass and organ damage due to the stages of parasite’s biological cycle. These injuries, when identified at slaughter, result in elimination of the carcass or part of the carcass or organ as it cannot go to human consumption, generating an economic loss. Economic research of animal health aims to quantify the financial effects of diseases so that methods can be developed to optimize decisions when animal populations are affected and determine the costs and benefits of disease control (Dijkhuizen & Morris, 1997)
