Resumo

O objetivo desta pesquisa foi identificar as bactérias presentes no ar circundante de uma oficina agroindustrial e seus possíveis riscos ocupacionais. Procedemos à caracterização das atividades que acontecem na oficina, localizada no cantão Bolívar, província de Manabí, Equador, por meio da aplicação de entrevistas semiestruturadas e observação direta. Posteriormente, foi determinado o grau de contaminação bacteriana por meio da aplicação de monitoramento ambiental; foram realizadas duas amostragens em sete pontos. A coleta bacteriana foi realizada por sedimentação por gravidade. Para determinar as possíveis doenças que estes podem causar, os microrganismos coletados foram identificados usando ágar Petrifilm Staph Express para Staphylococcus aureus e ágar cristal violeta-vermelho-bilida-glicose neutra para Enterobacteriaceae. A maior carga microbiana foi encontrada no consultório com 270 UFC/m³ de ar. A amostragem 1 atingiu até 848 UFC/m³, sendo considerada contaminada, e na amostragem 2 a carga bacteriana foi de 550 UFC/m³, resultando em pouca contaminação. Não há cepas de Staphylococcus aureus, embora haja a presença de Enterobacter aeroneges nas áreas de entrada de matéria-prima e armazenamento de gelo. Por esse motivo, concluiu-se que, se não houver medidas de higiene adequada, o pessoal fica suscetível a contrair infecções por Enterobacter aeroneges.
