       FDA Lists Sterilox Food Safety Solution for Food Contact

Sterilox Solution formally recognized as safe for direct contact with food

MALVERN, PENNSYLVANIA, AND STAFFORD, UK, May 23, 2007-Sterilox Food Safety, a division of PuriCore (London Stock Exchange: PURI), today announced it received notification that the US Food and Drug Administration (FDA) formally listed its Sterilox Solution as an approved food contact substance. This FDA Food Contact Substance Notification (FCN) is specific to the Sterilox System and formally recognizes the Sterilox hypochlorous solution for use as a food safe sanitizer to be used when re-hydrating or rinsing fresh produce including leafy green vegetables.

The Sterilox System is already used by leading US supermarket retailers to improve the safety and freshness of produce in supermarkets. The Sterilox Solution-which mimics the natural anti-microbial hypochlorous solution produced by the human body to fight pathogens-is highly effective at killing a broad range of pathogens and spoilage organisms including E.coli, Salmonella, Staphylococcus, Listeria, norovirus, avian influenza, yeast, and molds.

"This FDA Food Contact Notification represents yet another validation of our technology, and it builds on our existing EPA and other regulatory approvals for the use of the Sterilox Solution on fresh produce," said Tom Daniel, Senior Vice President of Sterilox Food Safety. "Pursuing a formal FCN listing also demonstrates that Sterilox Food Safety remains committed to leading and working with the food retail industry to improve the safety and freshness of produce for supermarket chains and their customers. Food retailers rely on the Sterilox System as an added layer of brand protection in the stores' comprehensive food-safety plan that starts with the grower and ends with the consumer."
