BABSON COLLEGE COMBATS NOROVIRUS WITH PUREGREEN24

PURE Bioscience (NASDAQ: PURE) and PureGreen, LLC today announced that PureGreen24 hard surface disinfectant was purchased by Babson College, the top ranked entrepreneurship business school in America, and is now being used as part of a comprehensive strategy to fight the recent Norovirus outbreak at the College. PureGreen24, powered by silver dihydrogen citrate (SDC), offers excellent protection against the Norovirus. The disinfectant is being used to protect the staff and students now that the campus has reopened after a four-day closure in which 174 cases of the gastrointestinal illness were reported. PureGreen24 is being used in all of the academic and administrative offices and has also been made available to students.

According to Shelley Kaplan, Associate VP for Facilities Management & Planning, "I was extremely pleased to find a green solution to this difficult issue. PureGreen24 disinfectant fits perfectly into our ongoing sustainability program efforts on campus and is being used to keep Babson College a green and healthy place to learn."

David L. Stetson, Co-Founder of Pure Green, LLC, commented that, "We responded quickly to provide a solution to the outbreak at the college. Our mission is to remedy situations such as this one without the use of toxic chemicals. We are pleased that Babson College has resumed its normal class schedules and that PureGreen24 will be part of the ongoing disinfecting routine."

"As the sole supplier for SDC, our 'just in time' bottling operation to distributors enabled us to immediately package and ship product to support Pure Green's need to move swiftly to fill this order," added Michael L. Krall, President and CEO of PURE Bioscience. "SDC is the first new disinfectant antimicrobial to be registered with the EPA in more than 30 years. The ability to kill the Norovirus is only one important application of the SDC molecule. It carries a 30-second kill time on standard indicator bacteria, a 24-hour residual kill on standard indicator bacteria, a 2-minute kill time on some resistant strains of bacteria, a 10-minute kill time on fungi, a 30-second kill time on HIV Type I, and a 1-10-minute kill time on other pathogenic viruses."
