Scientists reduce pathogens in poultry packaging

Scientists at the University of Glasgow have developed a new method to make packaged food safer for consumers and more long-lived on the shelf by harnessing the germ-killing power of ozone. In tests, the method has proved successful when used with poultry products.

Dr Declan Diver and Dr Hugh Potts of the University’s School of Physics and Astronomy have prototyped a system to rapidly, safely and temporarily turn some of the oxygen inside the sealed packaging into ozone, a very effective germicide.



Plasma generated by a retractable device held briefly against the surface of plastic or glass packaging splits the bonds between oxygen molecules (O2) inside the packaging which then reform as ozone (or O3). The ozone naturally returns to its original state after just a couple of hours – more than enough time for any mould, fungi or bacteria on the packaging’s contents to be destroyed without adversely affecting its taste.



The product’s effectiveness as a germ-killer also extends food’s shelf-life by at least one extra day, which could go a significant way to cutting down on the seven million tonnes of food discarded in the UK each year.



The efficacy of the prototype of the product, being brought to market by a University spinout company called Anacail,  has been proven at leading UK test labs including Campden BRI in Gloucestershire. Tests have shown an increase in shelf-life for products including bread and muffins, and a significant reduction of many pathogens in poultry including campylobacter, pseudomonas, and E.coli.



The product is being brought to market by a University spinout company called Anacail,. Anacail, which means ‘shield’, ‘preserve’ or ‘protect’ in Gaelic, was founded in January 2011 and has recently raised £750,000 of seed funding from leading technology commercialisation company, IP Group, and the Scottish Investment Bank, a division of Scottish Enterprise. Half of the funding is subject to satisfaction of certain technical and commercial milestones.
