Effect of modified pre-milking sanitizing practices on raw milk quality obtained from the dairy farmers of Tawau, East Malaysia

The aim of the study was to investigate the raw milk hygiene and quality among the small holder dairy farmers in Tawau area, Sabah. A total of 216 samples were collected from the respective dairy farmers and milk collecting centre located at Mile 15, Tawau. Preliminary results indicated that the quality of the raw milks obtained at farm level were inferior with high bacteria load (> than 10⁷ CFU/mL). The total coliform (2.9–3.8 CFU/mL) and Staphylococcus count (2.3–3.6 CFU/mL) were relatively high in certain samples. However, none of the food borne pathogens was found. Trace back study revealed that the causes of contamination were attributed by poor hygienic handling among the dairy farmers. A significant reduction in bacteria load was observed if the raw milk was chilled immediately at farm. The implementation of modified pre-milking sanitizing practices improved the microbiological quality of the raw milks obtained from respective dairy farms. Future studies will be emphasized on effect of prolonged storage on microbiological quality of raw milk that undergo two days collection system.
