Abstract
A method and means is provided for extending the shelf life of a food product by successively subjecting the food product to UV germicidal irradiation and an ozone/water or ozone/air treatment. The UV unit and the ozone unit may be reversed so that the food product is first treated with the ozone and then subjected to the UV germicidal irradiation treatment.
