Rapid Surface Chilling, a new cryogenic technology developed by Bernard Matthews Ltd and BOC, the UK’s largest industrial gases supplier and a leading supplier of food chilling & treatment process technology, could enable the poultry industry and the Food Standards Agency (FSA) in the UK to meet their 2015 joint Campylobacter reduction target.
Campylobacter bacterium is found on the surface of almost all raw chicken and is the most common cause of food poisoning in the UK with an estimated 500,000 cases leading to 80,000 primary care consultations and, in 2012, 85 deaths.
The cost to the UK economy is estimated to be in the region of £900m representing over half of the total cost of food-related illness.
BOC, a member of The Linde Group, and Bernard Matthews, the UK’s leading turkey farmer and supplier, have developed this new technology - which involves rapid chilling of the surface of the poultry using cryogenic vapour - in collaboration with the FSA and Campden BRI.
Industrial trials with a first prototype tunnel successfully demonstrated that Rapid Surface Chilling technology reduced campylobacter counts in chickens by an average of 90% (1 log reduction). The only independently verified treatment for campylobacter currently available, RSC technology uses cryogenically cooled liquid nitrogen delivered at approximately -196°C. This does not affect the taste, texture or appearance of the chicken and complies with current poultry meat marketing regulations.
Following industrial pilot trials in 2013/2014, BOC has continued to work actively with leading poultry suppliers and is now seeking agreement to start a full scale, in-line trial using Rapid Surface Chilling technology in Spring/Summer 2015.
The FSA’s 2015 target is to reduce the numbers of birds carrying the highest levels of contamination from 27 per cent of the total population slaughtered in the UK - more than 800 million a year - to 10 per cent. Rapid Surface Chilling technology represents a significant step forwards towards meaningful reductions in Campylobacter infection and offers an independently validated solution to an enormous and serious health concern in the broiler industry.Click here to watch BOC's prototype Rapid Surface Chilling tunnel undergoing early trials at a chicken processing site in the UK.
