PURE Bioscience Appoints Food Supply Chain Executive Janet Risi to its Board of Directors

Risi Fills Vacancy Left by Recent Passing of David Theno, Ph.D.

SAN DIEGO, CA (July 28, 2017) – PURE Bioscience, Inc. (OTCQB: PURE), creator of the patented non-toxic silver dihydrogen citrate (SDC) antimicrobial, today announced that it has named Janet Risi, President and CEO of Independent Purchasing Cooperative, Inc. (IPC), to its Board of Directors. Risi joins as an independent director with deep executive leadership experience, and she will also be a member of PURE’s Compensation Committee.

IPC was founded by Risi in 1996 and has since become the gold standard for foodservice supply chain management – supplying all goods and services to SUBWAY®. Today IPC annually manages in excess of $5 billion including food, packaging, equipment supplies and other services.

Risi’s many contributions include her service on the SUBWAY® Strategic Planning Council which aided the chain’s growth from 7,000 to 40,000+ units worldwide. She also assembled an impressive leadership team which has delivered more than $2 billion of savings to the SUBWAY® franchisees – all while increasing quality and food safety standards.

Prior to IPC, Risi started her career with Ralston Purina Company in 1981 as a commodities buyer. Risi later worked with other food industry leaders such as Jack in the Box, Chef America, Inno-Pacific Group and Burger King.

Janet Risi said, “It is clear to me from my many years of food industry experience that food safety is an increasing priority all along the food supply chain. The significant step-up in food safety provided by PURE’s non-toxic SDC antimicrobial -- and the opportunity to be part of the solution -- is a big part of what attracted me to work together with the PURE Board.”

Hank R. Lambert, CEO of PURE added, “As an accomplished food industry supply chain leader with extensive experience as a successful foodservice executive, we welcome Jan to the Board and look forward to her making valuable contributions to PURE’s growth strategy.”

Risi is the sixth member of PURE’s Board, filling the vacancy left by the recent passing of food safety scientist David Theno, Jr. Ph.D., who served as an independent director for PURE since 2013. Dr. Theno was a widely respected food safety expert who tirelessly advocated for companies to embrace food safety standards. Throughout his career he made important and unparalleled contributions to help make the food supply in the U.S. safer, and will be sorely missed.
