It had been recommended for a long time that premilking udder/teats preparation should be done by scrubbing them with wet towels to remove contamination. However, dry paper towels applied only to teats has come into common use nowadays, mainly for the reduction of labour. Our objective here was to determine the effects of different methods of pre-milking teat preparation and liner disinfection on total bacterial counts in raw milk, using nineteen Holstein milking cows. The highest bacterial count was obtained when liners were rinsed with sanitizer and teats were scrubbed with a wet towel, and the lowest counts were recorded when liners with no treatment were used, and teats were scrubbed with a wet towel followed by a dry paper towel. The results strongly suggest that the most important factor in producing hygienic raw milk is dry teats after scrubbing with the towel soaked in disinfectant and that teat-cups liners dipping in disinfectant every interval between machine removal and attachment is not very useful if they remain moist.
