The antimicrobial efficiency of essential oil of the Lippia origanoides was held in the presence of organic matter in teats of dairy cows and milking utensils. 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.
