PURE Resubmits Food Contact Notification to FDA for SDC Antimicrobial Use in Produce Processing

SAN DIEGO, CA -- (Marketwired) -- 09/09/15 -- PURE Bioscience, Inc., (OTCQB: PURE), creator of the patented silver dihydrogen citrate (SDC) antimicrobial, today announced that it has resubmitted a Food Contact Notification (FCN) to the US Food and Drug Administration (FDA) for Silver Dihydrogen Citrate (SDC) as a produce processing aid, expanding the use for SDC as a direct food contact substance.

PURE believes its FCN resubmission has adequately addressed the FDA's prior issues regarding the FCN originally submitted in October 2014 and withdrawn without prejudice in January 2015. The Company's resubmission follows the June 2015 resubmission of its FCN for poultry processing and constructive discussions with the FDA regarding results of new SDC testing on produce including lettuce, spinach and spring mix:

• Demonstrating materially significant reductions in, Salmonella, Listeria and E. coli in produce;
• While achieving silver residue levels that are approaching non-detectable; and
• Below existing FDA guidelines.

The Company's resubmission covers a broad range of processed vegetables and fruits that are most frequently associated with pathogen contamination.

PURE estimates that the US market opportunity for produce processing aids is currently in excess of $300 Million. Given the immediate market need and the proven superior efficacy of SDC against Salmonella, Listeria and E. coli, PURE believes it can achieve significant market penetration following receipt of FDA approval.

Produce - Leading Source of Foodborne Illness in the US The Centers for Disease Control and Prevention (CDC) estimates that produce was responsible for 46% of foodborne illnesses and 23% of foodborne illness-related deaths in the US between 1998 and 2008. Leafy greens were identified as the primary source of foodborne illness.

FDA Approval Process The FDA's FCN Program ensures the safety of Food Contact Substances (FCS) used in food processing and packaging. The FCN review period is 120 days, after which, if there are no concerns from the FDA, the FCN automatically becomes effective. With an effective FCN for produce, PURE can then immediately begin to commercialize SDC as a food safety solution into this new market.

Food Safety Problems - The SDC Solution US Public Health Statistics track pathogens in the food supply chain -- clearly demonstrating an ever increasing need for more effective, efficient and safer interventions. Processing aids or interventions commonly used in the US food industry today are highly toxic chemistries. In addition, pathogens can become increasingly resistant and render current interventions less efficacious.

PURE believes that SDC is a significant improvement over current processing chemicals and provides numerous important advantages, including:

• Does not induce bacterial resistance;
• More effective in reducing or eliminating pathogens;
• Easier to handle and dilute;
• Non-corrosive to processing equipment; and
• Non-toxic -- does not create noxious fumes.

Hank R. Lambert, CEO of PURE, said, "We feel confident to make the resubmission at this time because we have good reason to believe that our new test results included in our FCN resubmission clearly and adequately address the FDA's earlier concerns.

"Also, we are already working with a number of major produce and fruit processors who are using our SDC-based PURE Hard Surface� disinfectant. We believe our test results will be compelling to the FDA, and we are optimistic that the agency will view these results as a breakthrough in the industry's ability to dramatically reduce the pathogen risk that persists through produce processing -- thus opening an important and significant new market for SDC as a food safety solution," Lambert concluded.

About PURE Bioscience, Inc. PURE Bioscience, Inc. is focused on developing and commercializing our proprietary antimicrobial products primarily in the food safety arena -- providing solutions to the health and environmental challenges of pathogen and hygienic control. Our technology platform is based on patented stabilized ionic silver, and our initial products contain silver dihydrogen citrate, or SDC. SDC is a broad-spectrum, non-toxic antimicrobial agent, which offers 24-hour residual protection and formulates well with other compounds. As a platform technology, SDC is distinguished from existing products in the marketplace because of its superior efficacy, reduced toxicity and the inability of bacteria to form a resistance to it.
