A multistate outbreak of S. marcescens bloodstream infection was linked to contaminated MgSO(4) distributed nationally by a compounding pharmacy. Health care personnel should take into account the different quality standards and regulation of compounded parenteral medications distributed in large quantities during investigations of outbreaks of bloodstream infection.
