Scientific Peer-Reviewed Study at Grinnell Regional Medical Center Proves the Effectiveness of Antimicrobial Copper

The results of the study are undeniable and validate previous independent studies on the effectiveness of copper. A new clinical study investigating the bacteria-killing properties of copper has proven once again that copper 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 around the world.

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 bacteria1 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

*Laboratory testing demonstrates effective antibacterial activity against Staphylococcus aureus, Enterobacter aerogenes, Escherichia coli 0157:H7, Pseudomonas aeruginosa and Methicillinresistant Staphylococcus aureus (MRSA). When cleaned regularly, CuVerro® surfaces kill more than 99.9% of bacteria within two hours of exposure and continue killing more than 99% of bacteria, even after repeated contamination.
