A practical look at sink-drain biofilm risk, hard-to-clean surfaces, and where chemical-free dry steam can fit in healthcare and long-term care cleaning workflows.

The CSA Z317.12:25 standard for infection prevention emphasizes the critical role of addressing biofilms in healthcare facilities to combat healthcare-associated infections (HAIs). Effective cleaning requires physical force and thermal interventions, rather than reliance solely on chemical disinfectants, to remove biofilms and protect patients and staff from persistent pathogens.

Annually, over 220,000 Canadian patients develop HAIs, costing our system $1 billion and contributing to up to 12,000 preventable deaths. A significant contributor to this persistent threat remains largely out of sight and often misunderstood the pervasive presence of biofilms.
