Presença de Pseudomonas spp em função de diferentes etapas da ordenha com distintos manejos higiênicos e no leite refrigerado

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 1.97X104CFU mL-1 (equipments), when sanitary procedures were adequate, but from de 8.71X102CFU mL-1 (teats surface) to 1.6X105CFU mL-1 (refrigerated milk) when sanitary procedures were inadequate.
