Sterile sections of rubber and stainless steel milk transfer pipeline were inserted sequentially into a milking installation and soiled with fresh raw milk over a period of 5 d. The resultant adherent microbial population was removed and the generic composition of mesophilic and psychrotrophic types was determined. In all cases Acinetobacter spp. were found to predominate (59.5–75.6%). The generic composition of the raw milk used to soil the milking unit (with inserted pipe section) was determined once during each 5‐d soiling period. In general the milk was found to contain a mixed flora in which Gram‐positive organisms predominated.
