APPENDIX BmICROBIOCIDAl CONTROl mEAsUREsNote: the control measures described in this appendix are presented as descriptive examples only and require validation prior to use with respect to their effectiveness and safe use.Microbiocidal or practical elimination control measures act by reducing the microbial load, for instance through killing, inactivation or removal.Many microbiological control measures have multiple functions. Some microbiostatic control measures also have microbiocidal effects, the degree often depending upon the intensity at which they are applied (e.g. pH reduction, refrigeration, freezing, preservatives and indigenous antimicrobial systems).Pasteurization and other heat treatments of milk that have at least an equivalentefficiency are applied at such intensities (sufficient time/temperature combinations)that they practically eliminate specific pathogens. They have therefore beentraditionally used as key microbiocidal control measures in the manufacture of milkproducts. Non-thermal microbiocidal control measures with similar efficiencies arenot yet applied at such intensities that will render the milk product safe at the pointof application.
