Severe Yersinia enterocolitica sepsis after blood transfusion.

A 23-year-old male received multiple blood transfusions following complicated thoracic surgery. He developed progressive haemorrhagic shock and multiple organ dysfunction syndrome. Blood cultures grew Yersinia enterocolitica. The patient was proven negative for Yersinia enterocolitica; however, one of the donors was found to be positive. Although strict selection of blood transfusion donors is warranted in the Netherlands, contamination of blood components may still occur and therefore should be considered whenever adverse events occur during or after blood transfusion.
