WHC EMS Evaluates Innovative Bactericidal/Antimicrobial Copper Alloy Coating on a Stryker Power-PRO XT Stretcher

WHC EMS is evaluating CuVerro​ Shield™ by Aereus Technologies, which is an EPA registered bactericidal/antimicrobial copper alloy, on one of our Stryker Power-PRO XT stretchers. Both the upper and lower lifting bars as well as the pull handle of the stretcher were coated with CuVerro Shield™. The antibacterial properties work 24/7 in-between cleaning, never washing out or wearing away. All standard disinfectant wipes are compatible with the copper alloy. CuVerro is tarnish-resistant and will not oxidize and turn green like pure copper.

CuVerro Shield™is made from up to 100% recycled copper material and is 100% recyclable. In fact, nearly all of the copper mined to date is still in circulation because the recycling rate of copper is higher than that of any other engineering metal.

A recent study by published in The New England Journal of Medicine by the National Institutes of Health, CDC, UCLA and Princeton University scientists found SARS-CoV-2 (the virus which causes COVID-19 [the disease]) remains “active” on plastic for 2-3 days but has a half-life of only 46 minutes on copper alloy surfaces (van Doremalen, Neeltje et al., 2020).

The EPA has evaluated the acute toxicity of copper and found there to be "no risk to public health." Since early human existence, copper has been an essential material in many applications.

CuVerro Shield™ Public Health Claims

Based on EPA Registration, products coated with CuVerro can be marketed with the following public health claims:

Laboratory testing has shown that when cleaned regularly, this surface:

- Continuously reduces bacterial contamination, achieving 99.9% reduction within two hours of exposure, when cleaned regularly.
- Kills greater than 99.9% of Gram-negative and Gram-positive bacteria within two hours of exposure.
- Delivers continuous and ongoing antibacterial action, remaining effective in killing greater than 99.9% of bacteria within two hours.
- Kills greater than 99.9% of bacteria within two hours, and continues to kill more than 99% of bacteria even after repeated contamination.
- Helps inhibit the buildup and growth of bacteria within two hours of exposure between routine cleaning and sanitizing steps.

CuVerro is proven effective against the following 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 HAIs
- 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
