CuVerro® bactericidal copper surfaces represent the first and most effective (solid surface) class of EPA-registered materials that kill [qtip:bacteria|Laboratory testing has shown that when cleaned regularly CuVerro® surfaces demonstrate effective antibacterial action against … MRSA (Methicillin-Resistant Staphylococcus aureus), Staphylococcus aureus, Enterobacter aerogenes, Pseudomonas aeruginosa, Escherichia coli O157:H7,VRE (vancomycin resistant enterococci) …] continuously, 24 hours a day. CuVerro® complements routine environmental-surface cleaning and infection control practices by helping to keep surfaces continuously cleaner.
CuVerro® alloys have been put through the paces, with rigorous GLP (Good Laboratory Practices) testing for EPA evaluation of copper’s effectiveness in killing [qtip:bacteria|Laboratory testing has shown that when cleaned regularly CuVerro® surfaces demonstrate effective antibacterial action against … MRSA (Methicillin-Resistant Staphylococcus aureus), Staphylococcus aureus, Enterobacter aerogenes, Pseudomonas aeruginosa, Escherichia coli O157:H7,VRE (vancomycin resistant enterococci) …] responsible for hospital acquired infections. The testing focused on six disease-causing bacteria:
- E. coli O157:H7, a food-borne pathogen that has been associated with large-scale food recalls
- Methicillin-Resistant Staphylococcus aureus (MRSA), one of the most virulent strains of antibiotic-resistant bacteria and a common culprit of hospital- and community-acquired infections
- Staphylococcus aureus, the most common of all bacterial staphylococcus (i.e. staph) infections that can cause life-threatening diseases, including pneumonia and meningitis
- Vancomycin-Resistant Enterococcus faecalis (VRE), an antibiotic resistant organism responsible for 4% of all Healthcare-Associated Infection (HAI)
- Enterobacter aerogenes, a pathogenic bacterium commonly found in hospitals that causes opportunistic skin infections and impacts other body tissues
- Pseudomonas aeruginosa, a bacterium that infects the pulmonary tracts, urinary tracts, blood and skin of immunocompromised individuals
The three EPA approved GLP test protocols used to register Antimicrobial Copper with public health claims are:
- TEST 1-Efficacy as a Sanitizer: CuVerro® surfaces kill pathogens within two hours, proving its efficacy as a sanitizer.
- TEST 2-Residual Self-Sanitizing Activity: CuVerro® surfaces have residual self-sanitizing efficacy that doesn’t wear down or off over time.
- TEST 3-Continuous Reduction of Bacterial Contaminants: CuVerro® surfaces work continuously to reduce bacteria, 24 hours a day, even after repeated contamination.
These EPA tests6 used stainless steel as the control since it represent the most common material used in most hospital and surgical settings. The table below shows the net effectiveness of copper alloys compared to stainless steel in each of the three tests. Note that in Test 1, all of the bacteria have been killed on the copper surfaces while 4.9 million bacteria remain on the stainless steel which represents a significant threat to susceptible patients.
Based on EPA Registration, products made with CuVerro®, materials can be marketed with the following public health claims:
Laboratory testing has shown that when cleaned regularly, this surface:
- Continuously reduces bacterial7 contamination, achieving 99.9% reduction within two hours of exposure.
- Kills greater than 99.9% of Gram-negative and Gram-positive bacteria7 within two hours of exposure.
- Delivers continuous and ongoing antibacterial7 action, remaining effective in killing greater than 99.9% of bacteria1 within two hours.
- Kills greater than 99.9% of bacteria7 within two hours, and continues to kill more than 99% of bacteria1 even after repeated contamination.
- Helps inhibit the buildup and growth of bacteria7 within two hours of exposure between routine cleaning and sanitizing steps.
