Microorganisms (bacteria) should always be treated with caution. When plating the unknown sample, do not touch the swab or Petrifilmâ„¢ plate with your fingers. Wear gloves during collection and observations of prokaryotes. After plating, clean up work areas, place micropipettes and swabs in bleach solution, and wash hands in hot, soapy water. ................
