Use of irradiation to ensure the hygienic quality of fresh, pre-cut fruits and vegetables and other minimally processed food of Plant Origin. Proceedings of a final research coordination meeting

Sales and consumption of fresh pre-cut and minimally processed fruits and vegetables continue to grow. Changes occurring in life and eating styles, as well as demographic changes, have been cited as one of the reasons for the increasing demand for this type of produce. Since fresh fruits and vegetables are grown, processed or packaged in areas that may be exposed to microbial pathogen contamination, there is an increasing concern that these products may harbour microbial pathogens. In fact, a number of outbreaks linked to the consumption of contaminated fresh pre-cut fruits and vegetables have been reported. Prior to this Coordinated Research Project (CRP), studies on various chemical and physical methods of decontamination for their efficacy in destroying pathogens have been made. The use of ionizing radiation seems to have several advantages in relation to other alternative treatments; however more research was needed in order to demonstrate its efficacy without producing negative effects in the physiological traits of the fruit, and thus the commercial quality of these products. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture initiated in 2001 a Coordinated Research Project (CRP) on the Use of Irradiation to Ensure Hygienic Quality of Fresh, Pre-cut Fruits and Vegetables and other Minimally Processed Food of Plant Origin. This CRP included 15 participants from Argentina, Brazil, Canada, Chile, China, Egypt, Hungary, India, Malaysia, Pakistan, Portugal, Turkey, United Kingdom and the United States of America (2). Research coordinated meetings were held in Rio de Janeiro, Brazil (5-9 November 2001), Belfast, UK (14-18 April 2003) and Islamabad, Pakistan (25-29 July 2005). This publication presents the research results presented in the final research coordination meeting, where the work completed during the last five years (2001-2005) was analysed
