Proof of concept for detection of staphylococcal enterotoxins in platelet concentrates as a novel safety mitigation strategy.

Genomic analyses revealed that staphylococcal exotoxins are widely distributed and highly conserved among transfusion-relevant S. aureus isolates. Furthermore, SEs are significantly upregulated in PCs and detected at 30 h of PC storage. Therefore, bacterial toxin detection could supplement mitigation strategies to enhance PC safety.
