When raw milk is pumped to the transfer tanker, an automatic pump stopping
above 6°C should be used and this temperature should not be exceeded during transportation
(Dijkers et al., 1995). Transportation time should be as short as possible,
avoiding any unnecessary delays. Moreover, milk tankers should be cleaned and
disinfected at least daily, should be regularly inspected and maintained, and should
not be used for transport of any other materials in order to prevent microbiological
or chemical recontamination of milk (Burgess et al., 1994). The tanker driver should
not suffer from infections, should conform to hygienic rules, and should not have
access to stables in order to avoid contamination of milk with pathogens of human
origin.
