PURE Withdraws Food Contact Notification For SDC Antimicrobial Use In Raw Poultry Processing

SAN DIEGO, CA – PURE Bioscience, Inc. (OTCQB: PURE), creator of the patented silver dihydrogen citrate (SDC) antimicrobial, today announced that it has withdrawn the Food Contact Notification (FCN) it submitted to the U.S. Food and Drug Administration (FDA) in July 2014 for the use of SDC in raw poultry processing. PURE had submitted the FCN based on test results demonstrating that the SDC use provided a material significant reduction in Salmonella contamination in raw poultry.

The Company decided to withdraw its FCN, without prejudice, following its receipt of a Deficiency Letter from the FDA stating that the agency has developed new data that is currently under review. That data calls into question the long established safety levels of the cumulative dietary intake of silver in the US resulting from the food contact uses the agency had previously approved. As a result, the FDA indicated that it would not approve PURE's FCN absent new data or additional information that adequately addresses its new toxicity concerns. The FDA has not yet publically released this new data.

Going forward, the Company intends to work with the FDA and the food processing industry to collect or develop the additional data and information necessary to address the FDA's current safety concerns. The Company cannot provide an exact timeline of when it will be able to resubmit an FCN for the use of SDC as a direct food contact processing aid for treating raw poultry.

PURE had previously announced that it had submitted an FCN on October 8, 2014 for the use of SDC to reduce Salmonella, E. coli and Listeria in the processing of produce. Because the FDA is unlikely to approve any new uses of silver in food processing at this time, PURE anticipates that it will receive a similar Deficiency Letter from the FDA regarding the use of SDC in the processing of produce. If the Company does receive such a notification, it intends to similarly withdraw that FCN until it can provide the FDA with the additional data and information necessary to address the FDA's concerns.

Hank R. Lambert, CEO of PURE, said, "We are surprised and deeply disappointed in the need to withdraw our FCN and to delay our commercialization efforts into this new market for SDC. However, going forward we intend to work with the FDA and members of the food processing industry to address the FDA's request for additional data regarding exposure levels and the use of silver in food processing. Our confidence in SDC is not diminished. Given what we have learned from our earlier test results demonstrating SDC's ability to significantly reduce or eliminate pathogen levels in poultry and produce, our dedication does not waiver to drive SDC as a unique food safety solution into the food processing market." Lambert continued, "While we gather this data, we are continuing to aggressively commercialize our EPA registered PURE® Hard Surface disinfectant for use in the food service and food processing industries."
