SmartWash Boost pre-treatment removes 99.5% of pathogens before products reach wash lines

SALINAS, California — Producers know that it is impossible to eliminate 100% of pathogens in fresh produce. Food safety best practices include minimizing opportunities for contamination in the field and controlling cross-contamination in produce washing lines where a small amount of pathogens can spread to a large batch of produce. Smart washing solutions®a fresh produce industry leader in food safety, is expanding access and distribution of the company’s SmartWash Boost™ product, a patent-pending process aid used to pretreat fresh cut produce before washing and proven in studies conducted by the USDA-ARS to significantly limit the potential for cross-contamination before it begins.

SmartWash Boost™ combines the benefits of Pure Bioscience® PURE product® Control, containing silver dihydrogen citrate (SDC) – the patented molecule using stabilized ionic silver known for its antibacterial properties – and SmartWash Solutions chemistry to “boost” the established lethality of the free chlorine wash process , resulting in a 2.94 log reduction in Listeria monocytogenes and a 3.15 log reduction in E. coli 0157:H7.

“SmartWash Boost™ serves as an initial kill step, eliminating most E. coli and other pathogens before they have a chance to contaminate a wash line and spread to other products,” said said Steven Swarts, director of business development at SmartWash Solutions. “Combined with SmartWash® or SmartWash® Biological washing line chemistry and our Pinpoint Process Control™ systems, the result is the virtual elimination of the risk of outbreaks of leafy greens and fresh cut produce.

The recent study presented by USDA-ARS confirmed and documented the increased effectiveness of adding SmartWash Boost™ to existing food safety protocols. Measurements of tissue integrity and headspace gas composition also demonstrated that the shelf life, quality, and appearance of fresh-cut produce were not affected.

“Since the costs of an outbreak in terms of response, lost sales and damage to brand reputation are so great, it makes economic sense for companies to achieve the highest level of control possible. pathogens, and the combination of SmartWash® and SmartWash Boost™ provides that level of protection,” Swarts continued. “This USDA study has shown extraordinary results in fresh-cut lettuce, and we are continually researching other applications for this product, with promising data already obtained for several fruit and vegetable products that are not currently processed on a traditional washing line.
