Biosafety

Individuals are exposed in various ways to laboratory-acquired infections in microbiology laboratories. These involve the following:

  • Rubbing the eyes or nose with contaminated hands
  • Inhaling aerosols produced during centrifuga-tion, vortexing, or spills of liquid cultures
  • Accidentally ingesting microorganisms by putting pens or fingers in the mouth
  • Suffering percutaneous inoculation, that is, being punctured by a needlestick

Risks from a microbiology laboratory may extend to adjacent laboratories and to families of those who work in the microbiology laboratory. For example, Blaser and Feldman1 noted that 5 of 31 individuals who contracted typhoid fever from proficiency testing specimens did not work in a microbiology laboratory. Two patients were family members of a microbiologist who had worked with the Salmonella typhi, two were students whose afternoon class was in the laboratory where the organism had been cultured that morning, and one worked in an adjacent chemistry laboratory.

In the clinical microbiology laboratory, shigellosis, salmonellosis, tuberculosis, brucellosis, and hepatitis are
