Risk assessment for laboratory biosafety of Toxoplasma
Objective To quantitatively assessthe laboratory safety factors of Toxoplasma,thus to provide the basis of bio-safety for laboratory personnel engaged in the operation of Toxoplasma.Methods Firstly,the risk factors of Toxoplasma infection in laboratory were determined by the literature and Delphi investigation,then the weights of risk factors were determined by fuzzy analytic hierarchy process,thus the high risk factors of laboratory safety of Toxoplasma were determined.Results For the possibility of infection,the combination weights of the steps of contacting cats(dogs)in experiment and stool samples processing were 0.102 and 0.113,belonging to the risk factors.For the harm of infection,The combination weights of the steps of contacting cats(dogs)in experiment and stool samples processing were 0.113 and 0.102,belonging to the risk factors.Conclusion Active measures should be taken for protecting the susceptible factors of Toxoplasma infection.Equipping personal protection,wearing gloves,and operation in accordance with the laboratory SOP are essential to reduce the risk of laboratory infection in the treatment of the specimen.
