Introduction Development of Biosafety Practices 1941 - Meyer and Eddie 74 lab associated brucellosis infections in US 1949 - Sulkin and Pike 222 viral infections (21 fatal) Only 27% related to known accidents

Brucellosis is an infectious disease caused by the bacteria of the genus Brucella These bacteria are primarily passed among animals, and they cause disease in many different vertebrates Various Brucella species affect sheep, goats, cattle, deer, elk, pigs, dogs, and several other animals Humans become infected by coming in contact with animals or animal products that are contaminated with these bacteria

Precautions during sample collection Protect collector, colleague, staff o wear gloves, coat,(mask, glasses) . VHF: double gloves, filer-masks, boots VHF=(viral hemorrhagic fever) dispose needles in special containers, without re capping, disinfection(sodium hypochlorite 2.5%) incineration o clean working surfaces(hypochlorite) o decontaminate material(hypochlorite 10%)
