Staphylococcus aureus ATCC 25923, Salmonella choleraesuis ATCC 10708 and Escherichia coli ATCC 8739 were in contact with the oil by 5 min in suspension test with sterile powered milk used as organic matter. Spray containing solution 120 μL/mL of the oil was applied to teats and milking utensils and the results compared with the control group. In suspension test the essential oil showed activity in the presence of organic matter, being able to eliminate bacteria after 5 min of contact. The oil solution was able to significantly reduce the count of coagulase positive Staphylococcus spp and fecal coliforms in the teats (p<0,0001), and aerobic mesophilic in milking utensils (p<0,0001) with 5 min of contact. These results indicate that the essential oil of L. origanoides can be an alternative to chemicals that are commonly used in the management of milking dairy cows.A eficiência antimicrobiana de óleo de alecrim pimenta (Lippia origanoides) foi avaliada na presença de matéria orgânica em tetos de vacas leiteiras e utensílios de ordenha. Cepas de Staphylococcus aureus ATCC 25923, Salmonella choleraesuis ATCC 10708 e Escherichia coli ATCC 8739 estiveram em contato com o óleo no tempo de 5 min para o teste de suspensão, juntamente com o leite desnatado estéril utilizado como matéria orgânica. Um spray contendo solução de 120 µL/mL do óleo foi aplicado em tetos, teteiras e latões utilizados no armazenamento de leite e os resultados obtidos foram comparados com o grupo controle. No teste de suspensão, o óleo essencial de Lippia origanoides apresentou atividade na presença de matéria orgânica, sendo capaz de eliminar as bactérias após 5 min de contato. A solução de óleo de alecrim pimenta foi capaz de reduzir significativamente a contagem de Staphylococcus spp coagulase positiva e de coliformes termotolerantes nos tetos (P<0,0001) e de mesófilos aeróbios nas teteiras e nos latões (P<0,0001) utilizados na ordenha com 5 min de contato, tornando-os uma alternativa aos compostos químicos que são comumente utilizados.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorOutra AgênciaengUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASRevista Brasileira de Plantas MedicinaisLeiteAgentes ativos de superfíciesHigieneDesinfecção e desinfetantesEfficacy of essential oil of lippia origanoides in the disinfection of teats of dairy cows and milking utensilsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://sbpmed.org.br/admin/files/papers/file_RURHBZoSHn2e.pdfAnna Christina de AlmeidaErnane Ronie MartinsElisângela Ramieres GomesMaria Rosely Almeida de QueirozViviane Aguiar AndradeRodrigo Pereira MourãoOrlando Filipe CostaLourdes da Silva FigueiredoCintya Neves SouzaAlessandra Rejane Ericsson de Oliveira Xavierinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
