Which blood product is most associated with bacterial sepsis due to room-temperature storage?

• A. Packed red blood cells
• B. Platelets
• C. Fresh frozen plasma
• D. Albumin

Answer: (B)

Bacterial sepsis from transfusion is most linked to storage conditions that allow bacteria to multiply. Platelets are kept at room temperature (about 20–24°C) for several days to preserve their function. That warm, non-refrigerated environment lets any contaminating bacteria—from the collection process or skin flora—grow in the platelet units, increasing the risk of septic transfusion reactions. Packed red blood cells are refrigerated at 1–6°C, which slows or halts bacterial growth. Fresh frozen plasma is frozen and only poses a risk if contamination exists after thawing, but the freezing limits bacterial proliferation. Albumin is a sterile plasma derivative processed to be free of live bacteria and is stored under conditions that do not support growth. So the platelet storage conditions at room temperature explain why this product is most associated with bacterial sepsis.
