Although initiation of bacterial infection through contaminated blood products via transfusion is a relatively infrequent occurrence, bacterial sepsis as a result of transfusion of contaminated blood products has been reported. Examples of two implicated pathogens include Pseudomonas fluorescens and Yersina enterocolitica. Blood donors are interviewed at the time of donation regarding their overall feelings of general health, but unfortunately this cursory interview does not rule out contamination of blood in individuals with asymptomatic disease. Contamination of the donated blood with flora of the skin, or contamination during the processing of the blood unit may also occur.
 
 

1. Would you assume that the incidence of bacterial infection due to contaminated blood products is over or under reported. Why?

2. Suggest some ways that blood products could be screened to prevent transfusion associated infections. Are any of your suggestions practical?
