PURE Bioscience Receives EPA Registration of Expanded Efficacy Claims for its SDC-based Disinfectant Quick Kills against Additional Strains of MRSA Further Differentiate Powerful Broad-Spectrum Disinfectant from Competition SAN DIEGO, Powerful Weapon against Resistant Bacteria Regarding the expanded bacterial claims, Also added to the expanded label are two-minute kill claims on Campylobacter jejuni, one of the leading causative agents for human gastroenteritis worldwide, and Acinetobacter baumannii, an opportunistic nosocomial pathogen responsible for serious infections among soldiers wounded in Iraq and Afghanistan. Timely New Viral Efficacy Claims Expanded viral efficacy claims for PURE’s SDC-based disinfectant include a three-minute kill against Human Corona virus and Rotavirus and a ten-minute kill against Norovirus and Avian Influenza A. The Human Corona virus infects the gastrointestinal tract and the upper respiratory tract. The most notable of the Human Corona viruses is the SARS-CoV strain, which causes SARS (Severe Acute Respiratory Syndrome). Rotavirus is the most frequent cause of severe diarrhea among children and leads to the hospitalization of approximately 55,000 children in the Untied States each year. Noroviruses cause gastroenteritis, more commonly referred to as “stomach flu.” Norovirus is highly contagious and spreads rapidly throughout closed environments. Avian Influenza A viruses cause Avian influenza, often referred to as “bird flu.” Bird flu is a naturally occurring infection primarily in birds; however, infections with these viruses can occur in humans. Krall also commented on the new viral claims, “The standard viral kill time for disinfectants is 10 minutes, and our prior viral tests were performed to meet that standard. Based on the most recent three-minute viral test results against Human Corona virus and Rotavirus, we intend to begin retesting the other viruses and expect this SDC-based disinfectant to demonstrate quicker kill times. Following successful testing, we plan to submit the updated information to the EPA for registration.” Krall concluded, “Earlier this year, we identified significant and growing needs in the marketplace. In February we initiated independent third party laboratory testing to establish the data for these new claims, and the EPA label amendment was filed immediately upon completion of the battery of tests. With the recent issuance of the EPA’s registration of our expanded claims, we feel we are now well positioned to provide an even more comprehensive solution to help combat very serious world-wide health challenges.” SDC is an electrolytically generated source of stabilized ionic silver. As a platform technology, SDC is distinguished from competitors in the marketplace because of its superior efficacy, low toxicity and the inability of bacteria to form a resistance to it. The first new disinfectant active to be registered by the EPA in more than 30 years, SDC-based products are antiviral, antifungal and antibacterial, including a 30-second kill and 24-hour residual protection against standard indicator bacteria and a two-minute kill claim on MRSA (Methicillin-resistant Staphylococcus aureus), CA-MRSA, PVL-MRSA and VRE (Vancomycin resistant Enterococcus faecium). Moreover, SDC-based disinfectants are odorless, colorless, non-corrosive, non-flammable and are compatible with other disinfecting and cleaning chemicals. Private label SDC-based hard surface disinfectant products are currently available through a number of PURE’s distributors and are ideal for use not only as a household disinfectant but also in hospitals, schools, prisons and other closed population environments.
