PURE Bioscience’s Antimicrobial Technology Featured in Public Health Information Site TouchSurfaces.org Advocates Using SDC to Help Prevent Spread of H1N1, MRSA ‘Super Bug’ and other Dangerous Pathogens San Diego, Calif. – December 10,2009 – PURE Bioscience (NASDAQ: PURE), creator of the patented silver dihydrogen citrate (SDC) antimicrobial, announced that public health information website, TouchSurfaces.org, is recommending its SDC hard surface disinfectant as a highly effective weapon in eradicating H1N1, MRSA, VRE, Norovirus and other dangerous pathogens commonly spread on hard surfaces. The public health site is focused on educating visitors on how hard surfaces in the home, the workplace and in public venues can act as host to a multitude of infectious viruses and bacteria including H1N1, MRSA, HIV and others. The Centers for Disease Control and Prevention, and the American Society for Microbiology, cite growing evidence that contaminated surfaces enable the proliferation of germs. Research studies indicate the H1N1 virus can live up to twenty-two hours on hard surfaces and remain contagious for up to eight hours longer than seasonal flu. These “high touch” surfaces can include light switches, faucets, hand rails, door knobs, table tops, counters, elevator buttons, vending machine buttons, ATM machines, bathrooms and computer keyboards. Physician and medical correspondent Dr. Bob Arnot, who serves as chief medical educator for TouchSurfaces.org, says the website will provide the public with a medical practitioner’s advice on how to prevent the spread of disease causing pathogens from touch surfaces which pose a silent, yet imminent, threat. SpectraSan 24™, distributed by BioTech Medical, LLC, is featured on the site as an advanced broad spectrum disinfectant that kills a host of dangerous pathogens including MRSA, VRE and flu viruses including the pandemic 2009 H1N1 strain. PURE Bioscience’s SDC antimicrobial is the active ingredient in SpectraSan24. “SDC-based products such as SpectraSan24 are gaining acceptance as effective and responsible disinfectants proven to eliminate a wide range of dangerous pathogens in the home and workplace,” said Michael L. Krall, CEO of PURE Bioscience. “TouchSurfaces.org offers valuable public health information to help consumers protect themselves against a wide range of health threats to which they are exposed to every day. We are proud that our SDC technology is featured in this important education campaign, and we remain committed to bringing to market our powerful antimicrobial, which has been proven highly effective against these threats while retaining the EPA’s lowest toxicity rating.” About BioTech Medical, LLC BioTech Medical LLC is a North Canton, Ohio based division of privately-held Suarez Corporation Industries (SCI), a leading international marketing company.
