Pure® hard surface disinfectant remediates Listeria contamination in shuttered food facility

10 December 2014

White Paper Documents Successful Use of PURE’s SDC Antimicrobial in Closed Processing Plant - Equipment and Plant Now Deemed Safe for Production by FDA 

PURE Bioscience, Inc., creator of the patented silver dihydrogen citrate (SDC) antimicrobial, has announced that Dr. James L. Marsden, PhD., Distinguished Professor–Food Safety and Security Kansas State University, has released a White Paper which details the successful remediation of Listeria contamination in a food processing facility. The decontamination of the plant was achieved by utilising a cleaning and sanitising programme incorporating PURE® Hard Surface disinfectant. 
 
Summary 
•  The plant (operated by a specialty food manufacturer, co-packer and private label resource company that produced organic, all-natural and gourmet foods) was closed in July 2014 after two food pathogen-related events resulting in voluntary product recalls.  
•  The decontamination treatment plan for the plant was developed in cooperation with the US Food and Drug Administration (FDA) and included both PURE Hard Surface and PURE® Hi-Foam and Multi-Purpose Cleaner. 

Conclusion
             
•  PURE Hard Surface was extremely effective at eliminating Listeria from food processing  and packaging equipment in the plant and its environment. 
•  The FDA cleared both the equipment and the facility for food production. The building owner can now engage new food producers and return to online production. 
 
Hank R. Lambert, CEO, said that, “The  use  of our two  SDC-based products to successfully eliminate Listeria in the contaminated and closed plant is yet another important validation of the unique and superior efficacy of our powerful antimicrobial. PURE’s ability to play a  key role in  the  successful remediation of a plant closed due to ‘catastrophic pathogen-related food recalls’ is a perfect illustration of our core value proposition.   
 
“Our laser focus on food safety has allowed PURE to play an important role as a solution to an industry-wide problem. While protecting consumers from foodborne illness, we are helping companies protect their valuable brands, and avoid the major economic loss and damage resulting from a loss of consumer confidence.” 
 
Lambert continued, “This real-world example underscores the unique significance and relevance of SDC as part of both sanitation maintenance and prevention programmes.”  
 
Pre and Post Treatment Contamination Levels    
Post treatment sampling results (processed by independent third party Deibel Labs), showing all samples tested negative for Listeria, were provided to the FDA. 
•  The plant and equipment had been previously cleaned and sanitised using traditional treatments prior to the initiation of the reconditioning plan – however two pieces of processing equipment and a drain were then found to still be positive for Listeria.  
•  After completion of the remediation treatments which included multiple steps, including the application of the two PURE products, all 300 post treatment samples tested negative for Listeria
•  Citing the successful eradication of Listeria, the FDA issued a written release of the equipment and plant for manufacturing of FDA regulated products.
