Hydrogen peroxide and sodium hypochlorite disinfectants are more effective against Staphylococcus aureus and Pseudomonas aeruginosa biofilms than quaternary ammonium compounds

Caitlinn B. Lineback, Carine A. Nkemngong, Sophie Tongyu Wu, Xiaobao Li, Peter J. Teska and Haley F. Oliver

Eight disinfectants, including accelerated hydrogen peroxide®, regular hydrogen peroxide and quaternary ammonium compound (QUAT)-based products were tested against Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa) biofilms. The sodium hypochlorite and hydrogen peroxide-based products effectively decontaminated biofilms, whereas QUAT-based products did not.

Kennel Disinfectants for Microsporum canis and Trichophyton spp.

Moriello K.

Environmental disinfection is an important component of the prevention and control of dermatophytosis and is of particular importance in facilities housing large numbers of animals such as shelters and boarding kennels. Many factors need to be considered when selecting a kennel disinfectant including, but not limited to, efficacy, lack of toxicity or irritancy to animals and workers, cost, ease of application, and lack of corrosiveness to surfaces. Therefore, a comprehensive analysis was undertaken to determine if Accelerated Hydrogen Peroxide® (AHP®) would be a suitable alternative to other chemistries with known limitations.

Role of hospital surfaces in the transmission of emerging healthcare-associated pathogens: Norovirus, Clostridium difficile, and Acinetobacter species

Weber D.J., Rutala W.A., Miller M.B., Huslage K. and Sickbert-Bennett, E.

Health care-associated infections (HAI) remain a major cause of patient morbidity and mortality. An estimated 20%-40% of HAI’s are attributed to cross contamination by touching contaminated environmental surfaces, which play a role in the transmission of MRSA, VRE, norovirus, Clostridium difficile, and Acinetobacter spp. Transmission of these pathogens can be interrupted by appropriate hand hygiene and improving the cleaning and disinfection of environmental surfaces. This article focused on the role of surface contamination in the transmission of 3 emerging nosocomial pathogens: norovirus, C difficile, and Acinetobacter spp.

Cleaning and disinfecting environmental surfaces in health care: Toward an integrated framework for infection and occupational illness prevention

| AJIC 43, 2015 424-34

Hospitals and healthcare institutions are considering new innovative technologies such as Accelerated Hydrogen Peroxide® (AHP®) that achieve germicidal efficacy without compromising the safety of hospital staff in an effort to win the war against microbes. Health care associated infections (HAIs) are of particular concern to infection prevention professionals because many of these are caused by rapidly developing strains of multidrug-resistant organisms (MDROs) which can cause serious illness in both patients and health care workers. Therefore, cleaning and disinfecting are important parts of a comprehensive infection prevention strategy. While demand for more effective cleaning and disinfecting is growing, there is also increasing evidence that exposure to cleaning and disinfecting agents can result in acute and chronic health effects, particularly respiratory illness.

Can Antibacterial Wipes Spread Superbugs?

Reuters, The Canadian Press | Research Highlights

It is a common misconception that antibacterial wipes can be used on multiple surfaces without taking into consideration that instead of disinfecting, they may actually be spreading infectious pathogens. Regardless if staff have access to the best disinfectant on the market, education is paramount to ensure that a product's efficacy is achieved.

Bacillus anthracis Spore Decontamination in Food Grease

Amoako KK, Santiago-Mateo K, Shields MJ, Rohonczy E.

Bioterrorist attacks involving B. anthracis require rigorous decontamination efforts with a sporicidal disinfectant. This study tested a number of such products against B. anthracis, covered by a layer of food grease to simulate real-world complications. AHP® was the only disinfectant to achieve efficacy against these spores in food grease, at a 24-hour contact time.

Battling Germs that Keep Getting Stronger

Virox Technologies Inc. | Canadian Broadcasting Corporation

Battling Germs That Keep Getting Stronger, an article appearing on www.cbc.ca, highlights the emergence of antibiotic resistant organisms (AROs) in healthcare and the community and the potential role certain antibacterial products play in the development of such resistance. AHP surface disinfectant cleaners exhibit broad spectrum germicidal efficacy in rapid and realistic contact times. Hydrogen Peroxide, the active ingredient in Accelerated Hydrogen Peroxide® (AHP®), does not remain on the surface once it has dried, hence it does not provide the opportunity for bacteria to develop resistance to it. Therefore, AHP surface disinfectant cleaners can be used safely and effectively to reduce bacterial contamination on surfaces

Summary of Infection Prevention Practices in Dental Settings

Virox Technologies Inc. | Centers for Disease Control and Prevention

Transmission of infectious agents among patients and dental health care personnel in dental settings is rare. However, from 2003 to 2015, transmissions in dental settings have been documented. In most cases, investigations failed to link a specific lapse of infection prevention and control with a particular transmission.

Efficacy of an accelerated hydrogen peroxide disinfectant to inactivate porcine epidemic diarrhea virus in swine feces on metal surfaces

Holtkamp D.J., Myers J., Thomas P.R., Karriker L.A., Ramirez A., Zhang J. and Wang C.

This study tested the efficacy of an accelerated hydrogen peroxide (AHP®)-based disinfectant against porcine epidemic diarrhea virus (PEDv) in swine feces on metal surfaces. AHP® effectively inactivated the virus to low enough levels as not to cause clinical disease in live pigs.

Creating a biosecurity plan is good business

Pantaleon L.

Biosecurity is an essential part of animal care in preventing and/or minimizing the spread of contagious infectious diseases. Disinfectants are one facet of infection control and their use to prevent and control pathogenic microorganisms is well accepted. However, there is increasing concern regarding user, animal, and environmental safety for some commonly used disinfectants, and evidence of cross-resistance between disinfectants and antibiotics. Furthermore, there is also emerging evidence of bacterial resistance to some disinfectants. Therefore, it is important to understand the need to developing a proper biosecurity plan and to select disinfectants with a reduced potential for cross-bacterial resistance and a high level of safety and efficacy. Accelerated Hydrogen Peroxide® (AHP®) is a relatively new yet proven chemistry broadly used across a multitude of markets and industries known for its exceptional safety profile and microbicidal efficacy.
