National Product Launch to Include 24-oz and Convenient 4-oz Travel Size Spray Bottles SAN DIEGO, March 2 /PRNewswire-FirstCall/ -- PURE Bioscience (NASDAQ: PURE) today announced an agreement with Sterifide Laboratories for the distribution of PURE's silver dihydrogen citrate (SDC)-based disinfectant as OneShot Plus(TM) DD, a new technology in Sterifide Laboratories' OneShot Plus product line.

(Logo: http://www.newscom.com/cgi-bin/prnh/20060119/LATH060LOGO) Patrick Hurst, Vice President of Operations of Sterifide Laboratories, stated, "We live in a world where various types of organisms causing significant health problems have become resistant to previously effective disinfectants and antibiotics, and we are concerned about the growing threat of resistant pathogens like MRSA and VRE. Until recently, those pathogens were typically confined to hospitals and other closed environments but are now plaguing our communities." Hurst continued, "That is why we welcomed the opportunity to partner with PURE Bioscience in order to add the SDC-based disinfectant as a powerful weapon against MRSA and VRE to our OneShot Plus line of products. We are first marketing OneShot Plus DD through direct-to-consumer channels, and we plan to launch our 24-oz spray and convenient 4-oz travel size nationwide by April along with the other products in our OneShot line. The marketing program targets both English and Spanish speaking consumers." Michael L. Krall, President and CEO of PURE Bioscience, commented, "Sterifide will be uniquely positioned as it sells its SDC-based disinfectant through a new market channel. Sterifide's sales and marketing program should further increase awareness and acceptance of SDC as a truly revolutionary disinfectant." OneShot Plus DD OneShot Plus DD (currently completing registration in all 50 states) carries remarkable efficacy claims, including a 30-second kill time on standard indicator bacteria, a 24-hour residual kill on standard indicator bacteria, a 2-minute kill time on some resistant strains of bacteria including MRSA and VRE, a 10-minute kill time on fungi, a 30-second kill time on HIV Type I and 3-10-minute kill times on other pathogenic viruses. These claims distinguish the efficacy of OneShot Plus DD from many of the leading commercial and consumer products currently on the market, while maintaining lower toxicity ratings. Based on the EPA toxicity ratings from Category I (high toxicity) down to Category IV, OneShot Plus DD is a Category IV antimicrobial for which precautionary labeling statements are not required. This compares with Category II warning statements for most leading brands of disinfectant products. Each bottle of OneShot Plus DD features PURE's "Powered by SDC" logo.
