Research study at Grinnell Regional Medical Center

The results are undeniable. A clinical study investigating the bacteria-killing properties of copper has proven once again that the metal can play a leading role in fighting bacteria1 that cause healthcare-associated infections (HAIs). The paper also reached a second finding destined to shake-up the cleaning practices in the healthcare industry.

Published in the September 28, 2016 online edition of the American Journal of Infection Control and authored by Grinnell College associate professor of biology Shannon Hinsa-Leaure, Ph.D., the study showed that:

  • EPA-registered CuVerro® copper kills 99.9% of bacteria it comes in contact with including e. coli and superbugs MRSA and VRE.
  • Bacterial loads do not rebound in patient rooms where surfaces are made of copper, whether the room is occupied or not.
  • Germs quickly recolonize on surfaces made of stainless, plastic, or wood

No matter how well an institution cleans, germs can recolonize on non-copper surfaces, thus posing a threat of infection. Copper alloy surfaces address this issue by continuously killing bacteria. Healthcare-associated infections kill 75,000 US patients each year and cost the country $45 billion. Using copper fixtures as part of an integrated infection control program could ease this tragic condition.

Copper surfaces substantially reduce bacteria loads no matter where they are deployed - clinics, schools, health clubs, public restrooms, home kitchens, bathrooms, and even on pens and cell phone cases. According to a new opinion poll, a< majority of US consumers worry that the threat of infectious disease is growing.

  • Once consumers understand the bacteria fighting potential of copper, three out of four would consider using copper fixtures in their homes.
  • Only 4% of US consumers are aware of the bactericidal benefits of copper.
  • 60% of people who work in healthcare and food industries erroneously believe that stainless and plastic are the cleanest surfaces.
