Factors associated with consumer perception and conduct toward certified beef from Brazil.

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.

Epidemiological study of swine brucellosis in household farms in Federal District of Brazil / Estudo epidemiológico de brucelose em suínos em criatórios de subsistência do Distrito Federal, Brasil

Brucellosis is caused by 10 species of Brucella sp. and is responsible for huge economic losses. There are no specific prophylactic measures present for household pigs, which can be also reservoirs, in the brazilian National Program for the Control and Eradication of Animal Brucellosis and Tuberculosis. Therefore, we conducted a cross-sectional study of blood serum samples from 1793 household pigs from 823 farms in Federal District of Brazil. Serum samples were collected between August and October in 2011, 2012, and 2014 by the veterinarians under the Secretary of Agriculture. The Rose Bengal plate test (RBPT) was used for screening for antibodies against smooth Brucella sp. Positive results were confirmed by the slow agglutination test (SAT) and 2-mercaptoethanol test (2-ME). Among the 1793 samples screened with RBPT, 125 were positive for antibodies against smooth Brucella sp.; 46 (32%) of these samples showed agglutination in SAT, but only one (0.8%) sample was considered positive by 2-ME. The animal with the positive blood serum was traced back in a household farm whose owner had supplemented feeds with cow milk whey. For preventing swine brucellosis, it is necessary to prevent the cross-infection either by the consumption of contaminated cow milk or by direct contact with infected animals. The government policy should enhance the sanitary education for encouraging household farmers to employ prophylactic measures and ensure biosecurity. The present study results indicate that swine brucellosis risk in household farms occurs in a low prevalence rate in pigs from the Federal District of Brazil.

A brucelose, enfermidade causada por 10 espécies de Brucella sp, pode afetar várias espécies de animais. A doença é responsável por perdas econômicas em diversos setores, inclusive na suinocultura. Não existem medidas profiláticas específicas para suínos no Programa Nacional de Controle e Erradicação da Brucelose Animal e Tuberculose-PNCEBT. Foi realizado um estudo transversal durante o período de agosto a outubro em 2011, 2012 e 2014 para o estudo de soroprevalência. Os analistas veterinários da Secretaria de Agricultura coletaram sangue de 1793 suínos de 823 criatórios no Distrito Federal. O teste Rosa de Bengala (RBPT) foi utilizado como triagem para a pesquisa de anticorpos contra Brucella sp. Os resultados positivos foram confirmados pelo teste de aglutinação lenta (SAT) e teste de 2-mercaptoetanol (2-ME) em série. Das 1793 amostras testadas pelo RBPT, 125 foram reagentes; sendo que 32% (46) destas amostras apresentaram aglutinação no SAT, mas apenas uma (0,8%) amostra foi confirmada positiva pelo teste 2-ME. O animal positivo foi rastreado em uma chácara de subsistência cujo dono tinha hábito de fornecer soro de leite de vaca aos suínos. Para prevenira brucelose suína, é necessário evitar a infecção cruzada pelo consumo de leite de vaca contaminado ou pelo contato direto com animais infectados. A política do governo deve melhorar a educação sanitária para incentivar a agricultura familiar a empregar medidas profiláticas e garantir a biossegurança. Os resultados do presente estudo indicam que o risco de brucelosesuína é baixo entre os criatórios de suínos do Distrito Federal.
