Surgical sterilization as it now is practiced in Veterinary Medicine varies from careful technics carried out in an environment which would do credit to a human hospital, to the dipping of unclean instruments into a bucket of sheep dip solution of unknown strength. Even though economic considerations militate against the employment of expensive equipment and time-consuming technics, attention to a few simple details will greatly assist our approach to surgical asepsis.
