Dax Airscience whole room disinfection technology Airsteril is working with a large UK beef supplier to further reduce already acceptable bacteria levels on beef carcasses.

Dax selected two identical chillers, installed the technology in one chiller and also a 40ft refrigerated trailer. After 48 hours TVCs and entero had reduced by 90% and the carcasses in the untreated chiller had dropped only slightly.

Paul Anderson, technical director, routinly employs two types of systems for air treatment of food plants. He explains, "When the system is in operation, the Airsteril unit creates an advanced oxidation process consisting of hydroxyl radicals, super oxide ions and hyrdoxide ions. All are friendly oxidisers that revert back to oxygen and hydrogen after the oxidation of the pollutant.

"At this stage we are working with only a few companies to build a portfolio of successful applications before offering it to the open market, we are actively seeking a poultry producer to conduct work on campylobacter destruction."
