RESUMO:

Este estudo objetivou analisar os parasitos que infectam suínos e seus produtores em propriedades familiares em Tanguá, RJ, Brasil, realizando atividades extensionistas entre 2018 e 2019. Amostras fecais foram coletadas de 132 suínos, bem como raspados da pele da orelha de 125 animais. Além disso, 36 amostras fecais dos produtores e seus familiares foram analisadas. O material coletado foi processado pelo exame direto e por técnicas de sedimentação e flutuação. Parasitos gastrointestinais foram detectados em 88,6% dos suínos, principalmente coccídios (71,8%), Balantioides coli (55%), estrôngilos (40,2%) e Strongyloides ransomi (31,6%) que apresentaram significância estatística (p<0,05). Ectoparasitos foram identificados em 16% dos suínos, principalmente Sarcoptes scabiei var. suis (76,2%). Parasitos foram detectados em 19,4% das amostras fecais humanas, incluindo Entamoeba coli (19,4%), Ascaris lumbricoides (8,3%) e Trichuris trichiura (5,5%). A frequência de B. coli e S. scabiei var. suis foi estatisticamente significativa (p<0,05), quando se analisou os animais por faixa etária, tendo sido principalmente detectado nos animais mais velhos, como na fase de terminação. Os produtores de suínos participaram ativamente das atividades de extensão, incluído a palestra e a atividade “dia de campo”, que tinham como objetivo mediar informações sobre parasitos e suas medidas profiláticas. A situação nas granjas familiares de Tanguá demonstra a necessidade de realização de programas que apoiem tecnicamente esses produtores, que utilizam a suinocultura como fonte de subsistência.
