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

Data Suggests Processors Incorporating SDC Can Improve Pathogen Reduction Results 100-Fold With Only One Step

SAN DIEGO, CA--(Marketwired - Oct 9, 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 a produce processing aid, expanding the use for SDC as a direct food contact substance. Test results demonstrate significant log reductions in Salmonella, Listeria and E. coli O157:H7 when applied to leafy greens.

Meaningful SDC Produce Test Results
Testing performed at Kansas State University, under the direction of Dr. James Marsden, evaluated the efficacy of SDC against Salmonella, Listeria and E. coli O157:H7 on iceberg lettuce, spinach and cilantro. These leafy greens were chosen for evaluation because they are challenging to effectively treat during processing.

  • SDC achieved average reductions up to 2.36 log10 CFU/cm2 when applied alone as a spray and up to 3.10 log10 CFU/cm2 when combined with chlorine wash, simulating current processing steps;
  • Sensory evaluations of produce treated with SDC indicated no difference in color, appearance or odor to untreated controls; and
  • SDC had no effect on the nutritional composition of the produce.

Currently, processors target achieving only a 1 log10 CFU/cm2 reduction per intervention treatment. Data suggests that by incorporating SDC, processors can improve their results 100-fold with only one step. This represents a significant advantage to processors as well as improvement to the safety of processed produce going to the consumer.

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 illnesses.

Hank R. Lambert, CEO of PURE said, "The produce industry takes food safety seriously, and understands the importance and challenges in reducing contamination on fresh produce. Armed with the validation of this impressive test data, we believe SDC offers the industry a practical and effective solution to reduce the food safety threat presented by processed raw produce. This breakthrough for SDC can open what we estimate to be a new market opportunity in excess of $200 million in the US for PURE."

PURE recently completed a financing which provides the Company with sufficient working capital to support its operations for more than 12 months, excluding incremental revenue from its food safety commercialization efforts to accelerate commercialization of SDC as a food safety solution to prevent foodborne illness:

  • PURE now has two FCN's filed with the FDA (for processing poultry and for processing produce) and has begun testing SDC on meats (beef and pork).
    • The Company expects to file an FCN for processing beef and pork in early calendar 2015;
  • PURE is reinforcing existing sales and marketing capabilities for SDC as a hard surface disinfectant into QSRs (quick service restaurants) and food manufacturers/processors.

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 from filing, 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.
  • Subject to receipt of FDA approval, PURE expects to begin commercialization of SDC in calendar Q1 2015 for use in produce processing.
