  • Evaluating the antimicrobial activity of copper surfaces against Pseudomonas aeruginosa and Staphylococcus aureus 1 year after use in a microbiology laboratory, Vancouver General Hospital, Journal of Hospital Infection, March 2022.

This project confirmed previous observations and those of others that copper is an effective antimicrobial surface but can be affected by the type of disinfectant (with quaternary ammonium) having the least detrimental impact), and that the type of copper formulation impacts antimicrobial efficacy. While a difference between products in their immediacy of kill was observed, it is important to remember that the value of copper surfaces lies in their sustained antimicrobial efficacy, whereas stainless steel does not have any antimicrobial abilities.


Antimicrobial Activity Three Copper Alloys in Hospital Microbiology Labs Elservier March 29 2022.pdf


Key Points:

  1. Stainless steel at 1 and 2 hours is unaffected by H202.
  2. Trimco shows decreased antimicrobial activity with H202.
  3. EOS shows enhanced antimicrobial activity with H202.
  4. Aereus is unaffected by H2O2.
  5. The experiment will be repeated with modifications to account for the carry-over effect of the disinfectant.
