SAN DIEGO — PURE Bioscience has received U.S. Environmental Protection Agency (E.P.A.) registration for its silver dihydrogen citrate (S.D.C.)-based disinfectant and food contact surface sanitizer. The product will be marketed as IV-7 Ultimate Germ Defense for Food Contact Surfaces (IV-7) by PURE’s sales and marketing representative, Richmont Sciences LLC.

Classified as an E.P.A. Category IV disinfectant/sanitizer, IV-7 provides a combination of high efficacy, low toxicity and efficiency by rapidly eliminating dangerous pathogens, yet no rinse is required, according to the company.

IV-7 Ultimate Germ Defense for Food Contact Surfaces uses the broad-spectrum power of S.D.C. for use on surfaces and equipment in dozens of settings including food processing plants, farms, food storage areas, restaurants, fast-food operations, cafeterias, supermarkets, break rooms, schools, hospitals and other institutions, as well as in homes. IV-7 helps prevent cross-contamination in food contact environments and eliminates odors. In addition, the odorless IV-7 formula does not create irritating fumes, which is a particular benefit for restaurants, the company said.

“Our completion of the rigorous six-year federal registration process to bring this much-needed technology to market will improve public safety protections in food processing, packaging, distribution and service,” said Michael L. Krall, president and chief executive officer of PURE Bioscience. “We are working diligently to register the product in all 50 states; however, because many food industry companies operate in single states or regions, we plan to begin selling IV-7 Ultimate Germ Defense for Food Contact Surfaces on a state-by-state basis later this month as registrations are issued.”

Unlike traditional alcohol- or bleach-based surface disinfectants and sanitizers, IV-7 requires no hazard or warning statements and carries bacterial kill times as quick as 30 seconds. IV-7 provides powerful protection against a broad range of microbes, including those of particular concern in food processing and kitchen areas such as E. coli, Salmonella, Listeria and Campylobacter jejuni, as well as resistant pathogens such as MRSA. IV-7 continues to kill bacteria for up to 24 hours after use, the company said. However, with its E.P.A. Category IV toxicity rating, the lowest classification, S.D.C. is also labeled for use in sensitive areas such as those used by children.
