CDPH Health Advisory: Multistate Outbreak of Serratia Marcescens Bloodstream Infections May 2, 2018 Public Health 992 The CDPH Healthcare-Associated Infections (HAI) Program is working with multiple state and local health departments, the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA) to investigate cases of Serratia marcescens bloodstream infection in patients with central venous catheters or implantable medical ports. The investigation has identified a potential association with BD PosiFlush™ Heparin Lock Flush and BD™ Pre-Filled Normal Saline Flush syringes. To date, no products have tested positive for S. marcescens. BD has issued a voluntary recall of certain lots of BD PosiFlush™ Heparin Lock Flush and BD™ Pre-Filled Normal Saline Flush syringes due to potential contamination with S. marcescens.
