The occurrence of Pseudomonas spp, in raw and refrigerated (e to 8°C) bulk milk was related to milking steps at four dairy farms with distinct sanitary handling procedures. Average count for Pseudomonas spp at different sources, in the farms, varied from de 2.48X10²CFU mL-1 (teats surface) to 1.97X10(4)CFU mL-1 (equipments), when sanitary procedures were adequate, but from de 8.71X10²CFU mL-1 (teats surface) to 1.6X10(5)CFU mL-1 (refrigerated milk) when sanitary procedures were inadequate.
