Hepatitis E is caused by the hepatitis E virus (HEV) which is currently known to be a zoonotic pathogen transmitted by pigs. In Brazil, there is no information about the circulation of HEV in the swine herd of the Federal District. Therefore, a cross-sectional study was performed with sera from 449 domestic pigs, provided by the Secretary of Agriculture of the Federal District. Blood samples were collected between June and September 2014. A commercially available ELISA kit was used for the detection of IgG antibodies. High seroprevalence of antibodies to HEV was found, since 304 animals showed anti-HEV positive reactions (67.7%; 95% CI = 63.2%, 71.9%). The seropositivity presented no difference by gender or age. The results suggest that HEV circulates among domestic pigs in the Federal District and it can serve as a warning to the local public health system due to their possible involvement in human infections.A hepatite E é causada pelo vírus da hepatite E (HEV), considerado um patógeno de transmissão zoonótica que tem suínos como reservatórios. No Brasil, não há informações a respeito da circulação do HEV no rebanho suíno do Distrito Federal. Por isso, foi conduzido um estudo transversal com amostras de soro de 449 suínos domésticos provenientes de 234 propriedades, cedidas pela Secretaria de Agricultura do Distrito Federal. As amostras sanguíneas foram coletadas entre junho e setembro de 2014. Um kit de ELISA comercialmente disponível foi utilizado para a detecção sorológica de anticorpos IgG contra o HEV. Foi encontrada uma alta soroprevalência de anticorpos contra o HEV, uma vez que 304 animais apresentaram amostras reagentes (67,7%, IC 95% = 63,2%, 71,9%). A soropositividade não variou com relação ao gênero ou à idade. Os resultados sugerem que o HEV circula entre os suínos domésticos no Distrito Federal, e isso pode servir como um alerta para o sistema de saúde pública da região devido ao possível envolvimento desses animais em infecções humanas.

The aims of this study were to establish a relationship between consumers’ socioeconomic aspects, key meat attributes, and consumer perception and conduct toward traced beef in Brazil. The authors applied a structured form in 52 supermarkets in eight Brazilian cities, through interviews with 2.949 consumers, in 2012. Federal or state inspection stamp was the attribute that most influenced the consumers’ purchase decision (14.1%). Most of the interviewees (57.3%) had never heard about bovine traceability. Among those who had heard about bovine traceability, 63.2% would be willing to pay more for beef with certified origin. Consumers with higher education and income had a better knowledge about this type of certification, as well as older consumers, and therefore they would be willing to pay more for certified beef. This research suggests that educational level was the reason that most influenced Brazilian consumers during beef purchase.
