The Sinkbug Survey: Antibiotics, AMR, Chemicals and Plumbing

In this episode of Infection Control Matters, Martin Kiernan speaks with Dr. Nicole Stoesser about a large-scale, multi-centre study exploring the role of hospital sink infrastructure in antimicrobial resistance and pathogen dissemination. Representing the collaborative NITCAR-led "Sinkbug Consortium" we discuss surprising findings from 29 UK hospitals—including widespread antibiotic residues in sink traps—and reflect on the implications for sink design, waste disposal practices, and infection prevention strategies
