PURE Bioscience, Inc. and SmartWash Solutions®, jointly announced recent successful study results documenting that the pretreatment use of SmartWash Boost dramatically reduces the risk of foodborne illness in iceberg and romaine lettuce by increasing lethality. The pretreatment combines PURE Biosciences SDC based PURE Control® and SmartWash Solutions chemistry to “boost” the established lethality of the free chlorine wash process and increase E. coli die-off by more than 0.7 log when used with industry food-safety best practices. A recent study presented by the USDA-ARS shows that SmartWash Boost, a patent-pending process aid used to pretreat iceberg and romaine lettuce prior to washing, increases lethality and accelerates the death of E. coli during cold storage.
