PURE Bioscience Receives FDA Approval for Use of SDC Antimicrobial as Poultry Processing Aid to Reduce Pathogens, Including Salmonella

Pursuing USDA Approval – Targets Early 2016 for Commercialization
of PURE Control® as Direct Food Contact Food Safety Solution

SAN DIEGO–(BUSINESS WIRE)–PURE Bioscience, Inc. (OTCQB:
PURE), creator of the patented silver dihydrogen
citrate (SDC)
antimicrobial, today announced that the FDA has completed its review of
the safety and efficacy of the proposed use of silver dihydrogen citrate
(SDC) as a raw poultry processing aid and declared PURE Bioscience’s
food contact notification (FCN) to be effective as of December 18, 2015.

Dramatic SDC test results show consistent reductions in pathogen levels
— including the potential to reduce Salmonella on raw poultry to
below detection levels. A breakthrough technology, SDC is a non-toxic
food safety solution (safe for both people and the environment) –
delivering superior efficacy when compared with other processing aids
used in the market today.

USDA Approval Process Proceeding
The final step in the
regulatory approval process for commercialization of SDC-based PURE
Control® in poultry processing is to obtain USDA approval. With receipt
of the FDA’s approval, PURE is engaged in the review and approval
process with the Food Safety and Inspection Service of the USDA. This
process will involve plant trials under the authorization of the USDA.
The Company is working with partner processors and laboratories, has
developed protocols, and is designing the equipment necessary for the
trials.

The USDA trials are expected to take 45-60 days and following completion
and USDA review, PURE expects the USDA to issue a “Letter of No
Objection” and list SDC as an approved poultry processing aid in
Attachment 1, of the FSIS Directive 7120.1, Safe and Suitable
Ingredients Used in the Production of Meat, Poultry and Egg Products.

By early calendar Q2 2016, PURE anticipates having both of the necessary
regulatory approvals to begin commercializing PURE Control as a poultry
processing aid to reduce Salmonella and other pathogens to
prevent foodborne illness.

Hank
R. Lambert, CEO of PURE said, “Attaining FDA approval as a direct
food contact processing aid for poultry is a truly important and
catalytic milestone for PURE. It marks the first FDA approval for our
powerful SDC antimicrobial technology – and brings us just one step away
(USDA approval) from bringing PURE Control to the US poultry processing
market as a much needed, effective and non-toxic food safety solution.

“Each year, one in six Americans is sickened by foodborne illness,
according to the CDC. We believe that PURE Control will be an important
breakthrough to help make food safer for consumers, beginning with raw
poultry processors, as they combat prevalent contaminants that have
persisted through processing, including Salmonella and Campylobacter,”
concluded Lambert.

Poultry Processing – $350+ Million Annual US Market Opportunity

• In the US, poultry processing aids and interventions represents a
  $350+ million annual market. The average US poultry processing plant
  spends $1+ million annually in processing aids and intervention
  chemistries. PURE Control will be marketed to replace the toxic
  chemicals presently used during online reprocessing as well as in
  other intervention steps. The Company believes it can capture a
  significant share of this market based on PURE Control’s proven
  superior efficacy and lower toxicity compared to interventions
  currently in use.
• EPA approved PURE Hard Surface® disinfectant (applied on surfaces that
  come into contact with food but not directly on the food itself) has
  already been adopted for use on equipment and plant surfaces at a
  growing number of poultry processing plants. PURE will leverage this
  especially relevant foothold for its direct food contact initiative
  with PURE Control.
