PURE Control® Antimicrobial Listed as Safe and Suitable Ingredient in the USDA-FSIS Directive 7120.1 for Poultry Products

Commercialization Underway – Poultry Processors Preparing to Initiate In-Plant Validation for Poultry Parts Processing

PURE Bioscience, Inc. (OTCQB: PURE), creator of the patented non-toxic silver dihydrogen citrate (SDC) antimicrobial, today announced that PURE Control® antimicrobial is included in the newly updated list of Safe and Suitable Ingredients Used in Production of Meat, Poultry and Egg Products in the Food Safety and Inspection Service (FSIS) 7120.1 Directive (https://www.fsis.usda.gov/wps/wcm/connect/bab10e09-aefa-483b-8be8-809a1f051d4c/7120.1.pdf?MOD=AJPERES).

PURE has commenced commercialization of PURE Control to poultry processors, and two major processors are preparing to initiate their own in-plant validation work with FDA/USDA approved PURE Control to reduce Salmonella, Campylobacter and other pathogens to prevent foodborne illness.

Poultry Processing Market

• Approximately 80% of all poultry processed is packaged for sale as parts (not whole birds).
• The processing industry estimates that 65-75% of all poultry processing aids used are applied during pre- and post OLR (Online Reprocessing).
• PURE has targeted +10% (+$35 million) annual market share of the $350 million total US market. US poultry processing plants each spend approx. +$1 million annually in processing aids and intervention chemistries. PURE Control is being marketed to replace the less effective and toxic chemicals presently used during reprocessing and in other intervention steps

Hank R. Lambert, CEO of PURE, said, "This FSIS Directive listing is a major step forward for PURE. The production of poultry parts is the largest portion of the processing aids market. The fact that several processors are already preparing to initiate in-plant validation of PURE Control is a strong indication of the demand for a more effective and safer product for microbial reduction. Upon successful completion of their respective in-plant work, we expect these processors will become our first poultry customers for PURE Control. We know of no other equally effective, non-toxic solution – and believe PURE Control is the breakthrough solution the poultry industry needs and has been waiting for."

Given the importance of food safety, it is industry practice for customers of new food safety solutions like PURE Control to complete comprehensive internal validations prior to implementation. PURE welcomes and supports on-site customer trials with its technical support team.

Benefits of PURE Control

• The effectiveness of PURE Control addresses the top priority of the USDA in its Salmonella Action Plan, to reduce the presence of Salmonella in poultry sold to consumers by 50% from current levels.
  • Presently approximately 28% of raw poultry sold to consumers contains Salmonella. Recently, a disturbing 40% of processors exceeded the maximum allowable percent positive of those pathogens during a three-month period.
• While current toxic interventions can have a negative impact on yield, PURE Control has shown a neutral to positive processing yield impact.
• Uniquely effective, SDC also mitigates bacterial resistance, which is a problematic issue with other commonly used chemistries.

Ongoing USDA Testing for Poultry OLR Use

PURE continues its ongoing in-plant raw poultry processing trial in which PURE Control is applied through a spray cabinet to whole chicken carcasses during Online Reprocessing (OLR), and is expected to complete that work by mid-calendar Q4.
