PURE Submits Food Contact Notification to FDA for SDC Antimicrobial Use in Raw Poultry Processing

New Market Opportunity to Broaden as Food Safety Solution Provider

SAN DIEGO, CA--(Marketwired - Jul 14, 2014) - PURE Bioscience, Inc. (OTCQB: PURE), creator of the patented silver dihydrogen citrate (SDC) antimicrobial, today announced that it has submitted a Food Contact Notification (FCN) to the U.S. Food and Drug Administration (FDA) for Silver Dihydrogen Citrate (SDC) as an online reprocessing (OLR) antimicrobial for raw poultry processing. Previously reported test results demonstrated materially significant reduction in Salmonella contamination in poultry.

FDA and USDA 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. 
  • An FCN is considered to be proprietary as it applies only to the specific product and manufacturer or supplier identified in the FCN.
  • Upon the FDA's granting of the FCN, PURE will immediately submit the FCN to the Food Safety and Inspection Service (FSIS) of the USDA for a new technology review. 
    • As part of the FSIS review process, PURE will conduct three in-plant process validation and optimization trials with the authorization of the USDA. 
  • After completion of the three in-plant validation trials, PURE expects the USDA to issue a "Letter of No Objection" and list SDC as an OLR poultry processing aid in Attachment 1 of FSIS Directive 7120.1, Safe and Suitable Ingredients Used in the Production of Meat and Poultry Products. 
  • Subject to receipt of both FDA and USDA approval PURE will begin commercialization of SDC in Q1 2015 for use in poultry processing.

SDC Advantage
Data submitted as part of the Company's FCN showed that SDC achieved an average reduction in Salmonella of 2.75 log10 CFU/cm2 when applied as an OLR spray and 6.28 log10 CFU/cm2 when combined with an immersion chilling process simulating current U.S. industry practices. 

  • The importance of this data indicates that the use of SDC antimicrobial solution in poultry processing has the potential to enable plants to achieve non-detectable Salmonella levels post-chill process. 
  • Additionally, a sensory evaluation of SDC showed no difference in color, appearance or odor in treated poultry. The Company believes that these test results exceed current U.S. industry best practices. In addition, given the non-toxic properties of SDC, the Company believes there are safety benefits for users, production line personnel and the surrounding environment.
  • SDC offers a highly effective alternative to hazardous and difficult to blend chemicals currently used as OLR treatments in raw poultry processing. 
  • SDC is a significant improvement over current processing practices. The product is:
    • Easier to handle and dilute
    • Non-corrosive to processing equipment
    • Does not create noxious fumes
  • PURE believes that poultry processors will also benefit from the highly stable solution, ease of use and improved worker safety.

Salmonella - Most Frequently Reported Cause of U.S. Foodborne Illnesses
Salmonella is responsible for an estimated 1.3 million food borne illnesses each year. In testing, the USDA has found that 24% of chicken parts in the food supply chain were contaminated with Salmonella. The demonstrated ability of SDC to reduce Salmonella to levels below the detection limit, when applied during the on-line reprocessing of raw poultry products, provides the potential to dramatically reduce the amount of contaminated poultry parts sold to U.S. consumers.

The USDA's Salmonella Action Plan, a top Department priority, aims to significantly reduce the number of Salmonella related food borne illnesses in the U.S.. The USDA initiative drives increased scrutiny to poultry inspection and processing practices. Poultry processors need new, highly effective antimicrobial interventions that can provide a heightened level of control over Salmonella that current interventions are not achieving.

Hank Lambert, CEO of PURE said, "We believe that the test results included in our FCN submission, generated by incorporating SDC as an intervention component of an integrated food safety system for poultry processing, will be compelling to both the FDA and the USDA. We are optimistic that both agencies will view these results as a potential breakthrough in the industry's ability to dramatically reduce the Salmonella that persists through poultry processing -- thus opening a significant and important new market for SDC as a food safety solution."
