Resumo
O objetivo do presente trabalho foi o de avaliar os níveis de biossegurança, nos anos de 2001 à 2003, na totalidade das 10 (dez) granjas de reprodutores suínos (GRSC) do Estado de São Paulo certificadas pelo Ministério da Agricultura (MAPA) de acordo com os critérios de pontuação e resultados de provas e testes diagnósticos legalmente estabelecidos. Para o estudo da biossegurança, foram conferidos pontos (variando de 0 a 2) para cada critério (distancia em relação a outras unidades de criação, densidade de rebanhos num raio de 3,5 km, granjas fornecedoras de matrizes para reposição do plantel, distância entre a rodovia que transporta suínos, isolamento da granja (cerca e cinturão verde, controle de visitas, existência de quarentenário, origem da ração, transporte da ração). Foram realizadas 6.297 provas sorológicas para Peste Suína Clássica (2.023), Doença de Aujeszky (2.001), Brucelose (2.085), Leptospirose (188) e 1.001 testes de reação alérgica para tuberculose. Relativamente à biossegurança, 4 (quatro) granjas foram qualificadas com nível A, 5 (cinco) granjas como nível B e 1 (uma) granja com nível C. Relativamente aos resultados de provas e testes de diagnóstico, apenas 1 granja do nível A apresentou testes positivos para leptospirose no primeiro ano de certificação e a partir desta data passou a vacinar seus animais contra leptospirose à semelhança das demais 9 granjas devida à endemicidade da doença. Dentre as de nível B, uma granja apresentou animais infectados com M. avium e em uma granja de nível C foram detectados animais positivos para M. avium e brucelose no quarentenário. Estes resultados indicam necessidade de aprimoramento das medidas de biossegurança no tocante à prevenção e/ou controle de roedores sinantrópicos, de aves de vida livre e aquisição de animais de granjas também GRSC, porém, de nível igual ou superior.
The aim of this research is the evaluation of biosafety levels during the period from 2001 to 2003, in a total of 10 swine breeder farmers located in São Paulo state - Brazil and certificated by the Ministry of Agriculture according to scores and diagnostic tests legally established. For this purpose, each variable scored in 0 to 2 were: distance from other swine farms; herds density in 3,5Km ray area; breeder supplier farms; distance from road for swine transportation; farm isolation; control of visitors; installation for animal quarantine; ration origin and transportation. There were performed 6,297 diagnostic tests for Classical Swine Fever (2.023) - Aujeszky disease (2.001), Brucellosis (2.085), Leptospirosis (188) and 1.001 alergic tests for tuberculosis. As a result of biosafety, 4, 5 and 1 farms were scored respectively as A, B and C levels. For diagnostic tests, only one farm of level A had positive animals for Leptospirosis in the first year of certification and since then all the animals were vaccinated against leptospirosis, as the others 9 did due to the endemicity of this disease. In one farm among those of level B, it was diagnosed the presence of M. avium and in one farm of C level it was detected M. avium and in the quarantine station was diagnosed brucellosis. These results points up the need for improving the biosafety measures related to rodents and free life avian prevention and/or control and selection of GRSC breeder supplier farms with equal or higher biosafety level.
