PURE Bioscience Announces Distribution Agreement with Pure Green, LLC for SDC-Based Disinfectant

Pure Green, LLC Launches PureGreen24 – A Powerful Weapon Against MRSA

SAN DIEGO, CA February 5, 2008—PURE Bioscience (OTCBB: PURE) today announced the launch of PureGreen24™, a silver dihydrogen citrate (SDC)-based disinfectant distributed as a private label brand by Pure Green, LLC.  Under the terms of the distribution agreement, PURE will blend and bottle its patented SDC-based hard surface disinfectant for Pure Green.

EPA registered PureGreen24 provides broad-spectrum protection against bacteria, including MRSA, viruses and fungi and provides 24-hour residual protection against Staph, Pseudomonas and Salmonella.  PureGreen24 contains no ingredients categorized as “hazardous” by OSHA and meets school system and office building “green” standards.

David L. Stetson, co-founder of Pure Green, LLC, commented, “We believe that the SDC antimicrobial technology is superior to any other disinfecting product available and is an ideal solution to the growing Staph and MRSA threats currently faced by the general public and our school systems nationwide.  PureGreen24 is EPA registered for uses ranging from hospitals and medical clinics to mothers at home spraying PureGreen24 on children’s toys.”

Stetson continued, “We are rapidly developing PureGreen24 distribution partner relationships throughout the United States in order to meet customer demand. Institutions, offices and homeowners alike are attracted to PureGreen24 due to its powerful efficacy against deadly bacteria in combination with its workplace and family friendly technology.”

Michael L. Krall, President and CEO of PURE Bioscience, added, “Given the accelerating need for effective antibacterial products that fight the spread of MRSA and other dangerous pathogens, we continue to actively expand our distribution channels through partners like Pure Green, LLC.  We believe Pure Green’s commitment to improving human health and the environment, along with its aggressive marketing strategy and cutting-edge computerized customer service and distribution management systems, will help our SDC technology reach new, untapped markets, and will further strengthen the market positioning of our unique platform technology in the hard surface disinfectant segment.”

PureGreen24 is available for sale nationwide.  Prior to launching an SDC-based disinfectant, PURE’s private label distributors’ products must be sub-registered by PURE with the US Environmental Protection Agency (EPA) and each distributor must subsequently apply to all 50 states for individual state regulatory approval – a process that can take up to six months.
