Economic losses due to the occurrence of cysticercosis in cattle from cities located in Minas Gerais, Brazil

Abstract

Cysticercosis represents an important public health problem that can cause significant economic losses to the beef industry. The present study aimed to determine the prevalence rate of cysticercosis in cattle and estimate the economic losses to producers associated with this parasitic disease. Data were collected from the official sanitary inspection service of a slaughterhouse located in the city of Uberlândia, Minas Gerais, southeast Brazil, from 2009 to 2016. A total of 358,383 cattle from 46 cities in Minas Gerais, Brazil, were slaughtered, of which 4,243 were infected with cysticercosis (1.18%). A total of 5,194 cysticerci were detected in these carcasses, of which 4,548 (87.56%) were alive and 646 (12.44%) were calcified. Most of the cysticerci were located in the masseter and pterygoid masticatory muscles (72.41%). As to the classification of cysticercosis according to the degree of infection of organs and/or parts affected, mild infection was the most frequently observed (92.36%). Rural producers had a total of R$ 1,755,204.20 (US$ 537,526.80) of economic losses due to bovine cysticercosis during the time span of eight years covered by this retrospective study. The importance of the sanitary inspection of meat in the control of this major zoonotic diseases is emphasized.

Systematic review and meta-analysis of bovine cysticercosis in Brazil: current knowledge and way forward

“…From these articles, we identified two articles [11,26] describing BCC prevalence in several Brazilian states, covering a long period and including a large sample size. In addition, we found 12 articles containing information about the spatial distribution of BCC inside/within the states (Table 1), 13 articles describing risk factors or variables associated with BCC occurrence ( Table 2) and 4 describing the economic burden of BCC [7,22,28,30]. Furthermore, a set of 10 studies performed in Brazil were also included, regarding at least one aspect presented in discussion section, such as efficacy of chemical treatment (n = 1) [62], preferential infection sites (n = 2) [63,64], development of serological tests (n = 4) [65][66][67][68] and measures for BCC control (n = 3) [69][70][71].…”

“…BCC leading to reduced carcass value or total carcass condemnation at slaughter, results in important economic losses for the Brazilian beef sector. Four articles presented data about the economic burden [7,22,29,30].…”

Epidemiological analyses of cattle carcasses affected by cysticercosis and hydatidosis in the State of Rio Grande do Sul from 2014 to 2018

“…Economic losses resulting from cysticercosis have been estimated from US$175,000 to US$4 million due to the treatment, condemnation and disposal of carcasses in various countries. In turn, the annual losses associated with hydatidosis have been estimated at values ranging from US$ 72,000 to US$ 212 million in the productivity of different animal species (Jansen et al 2018b, Laranjo-González et al 2018, Rezende et al 2018, Henckel et al 2020). These numbers point out the need to adopt efficient control measures to reduce the occurrence of these zoonoses.…”

Impacto Econômico Aos Pecuaristas Decorrente Da Detecção De Cisticercose Bovina Em Um Abatedouro-Frigorífico Do Estado De São Paulo, Brasil

“…No trabalho de Guimarães-Peixoto et al (2012) no período de 2004 a 2008, os produtores do estado do Paraná tiveram um prejuízo relacionado a cisticercose bovina de aproximadamente R$ 119.626.428,00. Já no trabalho de Rezende et al (2018) os prejuízos gerados aos produtores de Minas Gerais no período de 2009 a 2016 ficou em torno de R$ 3.027.458,44. Além desses prejuízos, há outras perdas econômicas para a cadeia produtiva da carne que não foram avaliadas no presente estudo, como a depreciação da carcaça acometida com cisticercose pela realização de cortes necessários para a retirada dos cistos, condenação de órgãos, além dos custos para o frigorífico decorrentes da realização dos tratamentos necessários para inviabilização dos cisticercos e a impedimento da exportação dessas carnes.…”
