Mouth Pipetting: A Threat More Difficult to Eradicate than Small Pox

Perhaps no practice in the biomedical research laboratory has been more resistant to change than mouth pipetting. As Dr. Arnold G. Wedum pointed out in his third and final previously unpublished paper, which is published posthumously in this issue of JABSA, mouth pipetting was first recognized as a hazard in 1894 and largely went unabated for most of the twentieth century. Even at Fort Detrick the practice was not prohibited until 1963. At the National Institutes of Health and the Communicable Disease Center (now the Centers for Disease Control and Prevention) ofthe U. S. Public Health Service, mouth pipetting was not broadly discouraged until the 1970s.
