“…The North of the country had contamination, contusion and adenitis among the five most important causes; on the other hand, it was the only region that did not have cysticercosis among the main causes. The high prevalence of the taeniasiscysticercosis complex is linked to high human population density, and, therefore, the low human population density in the region and a sparsity of studies on the epidemiology and notifications of the disease in the region may be the causes for the low condemnation and use of cattle carcasses (Alves et al, 2017;Rossi al., 2014).…”

ResumoO Brasil é um grande produtor e exportador de carne bovina. Entretanto, carcaças com alterações anatomopatológicas podem causar prejuízos econômicos por receberem algum tipo de condenação ou aproveitamento condicional. O objetivo do trabalho foi analisar as alterações anatomopatológicas e os destinos dados as carcaças bovinas no Brasil, no período de 30 de março de 2017 a 31 de dezembro de 2019. Os dados foram coletados por meio do Sistema de Informações Gerenciais do Serviço de Inspeção Federal (SIGSIF), disponível online por meio do MAPA. Observou-se que foram abatidos 67.456.321 bovinos e 2,0% das carcaças foram condenadas ou aproveitadas condicionalmente. A região Sul do país obteve maior ocorrência de alterações anatomopatológicas nas carcaças (4,5%), enquanto o Nordeste obteve a menor (0,1%). O principal critério de julgamento de carcaças no país foi a condenação parcial, com 81,7% dos julgamentos estabelecidos. As principais causas de condenações e aproveitamento condicional foram contaminação (31,5%), cisticercose (21,2%), contusão (11,3%), adenite (7,4%) e abcesso (6,5%). Notou-se que a padronização dos registros no SIGSIF seria importante para coleta mais clara das informações e para o próprio registro por parte dos abatedouros. Evidenciou-se a importância da inspeção veterinária para garantir a comercialização de carnes seguras aos consumidores.

“…Updated spatial analysis of areas of occurrence of bovine cysticercosis in the state of Espírito Santo, Brazil Human population density, an important criterion since humans are the definitive hosts of the parasitosis, was considered a risk factor by Alves et al (2017) and Rossi et al (2015). However, this factor must be related to inadequate sanitation, because even in highly populated regions, adequate sanitation reduced the risk of cattle contact with T. saginata eggs (Abunna et al, 2008;Bavia et al, 2012;Boone et al, 2007;European Food Safety Authority, 2004).…”

The risk of bovine cysticercosis is mutable over time, since population habits, local infrastructure, and bovine herd size change through the years. Hence, the aim of this study was to update the risk map of bovine cysticercosis occurrence in Espírito Santo State, Brazil, by choosing the following risk factors: inadequate sewer service; bovine population per municipality; risk of flooding; and land use and occupation, examined with a mathematical model using the GIS program ArcGis 10.5. The risk map of occurrence demonstrated that the state is composed of 12.8, 24.5, 36.2 and 26.5% of areas of very high, high, medium, and low risk, respectively. The northern area stood out for areas of very high risk, with the cities of Linhares and São Mateus accounting for 99% of the area with this classification. Of the state's 78 municipalities, 15 had a portion of their territory with very high risk, 11 had over 50% of the territory with high risk and all except Irupi (100% of low risk) had some percentage of medium risk. These findings demonstrate the areas where actions to prevent bovine cysticercosis should be preferentially conducted.

“…These states are located mainly in the Southeast and South regions, which had the highest BCC prevalence values in the prevalence meta-analyses and also a higher human population density (86.82 and 48.58 inhabitants/km 2 , respectively) [72]. In the UK, farms situated close to a permanent potential source of human fecal contamination are considered with a higher risk for BCC [73] as the presence of infected humans results in environmental contamination with T. saginata eggs, mainly in areas with inappropriate sewage systems [24]. The wastewater treatment in Brazil evolved from 42% of the Brazilian human population in 2007 to 50.3% in 2015, leaving more than 100 million of inhabitants without proper sanitation.…”

Background: Taenia saginata taeniosis/cysticercosis has been well studied in several countries. Brazil is one of the most important beef exporting countries and has one of the highest cattle population size in the world. In this country, bovine cysticercosis (BCC) remains the most frequent reported zoonosis detected during post-mortem inspection, resulting in costs for the beef sector and public health. We performed a systematic literature review regarding data about BCC epidemiology in Brazil and meta-analyses for its prevalence in different administrative regions and the distribution over time, and based on this discussed possible control strategies. Methods:A systematic review was conducted to obtain data about BCC in Brazil using the words "bovine cysticercosis" and "Brazil" to construct the search phrase. The inclusion criteria used to select articles were: (i) published from 2000 to 2018; (ii) full text available online in Portuguese or English; and (iii) contain information at least regarding one of the following aspects of BCC in Brazil: prevalence, incidence, spatial distribution, risk-factors, economic burden and measures for control. Results:A set of 42 articles was included, covering the prevalence of BCC in Brazil, ranging between 0.01-18.75%. Prevalence results of 40 articles were included in a meta-analysis per administrative region. The highest prevalence was found in the South (3.4%; 95% CI: 2.0-5.2%), followed by the Southeast (2.7%; 95% CI: 1.9-3.6%), Northeast (1.5%; 95% CI: 0.6-2.7%), Central-western (0.9%; 95% CI: 0.3-1.7%) and North (0.0%; 95% CI: 0.0-0.6%) region. In addition, a reduction in prevalence over time was observed in all the evaluated states except for Alagoas and Pará. Conclusions:Besides the large availability of data, a critical lack of information about BCC epidemiology remains in Brazil. Nevertheless, the available data on prevalence, high risk-areas and risk factors should contribute to a better understanding of transmission and the formulation of recommendations for control. A One Health approach will be required to reduce T. saginata taeniosis/cysticercosis prevalence and the consequent economic burden for the beef sector in Brazil, one of the most important beef exporters in the world.
