he Norwegian Food Safety Authority (NFSA) has commissioned the Norwegian Scientific Committee for Food and Environment (VKM) to identify quarantine pests and potential quarantine pests that may be dispersed with organic waste, wastewater or sludge from packing plants that handle domestic and imported potatoes and vegetables. The NFSA asks VKM to identify risk reduction options and evaluate the effectiveness and feasibility of the options. The VKM Panel on Plant Health did the assessment. The crops relevant for the assessment are potatoes, bulb, carrots, onions and other root vegetables that are susceptible to damage from quarantine pests. Norwegian potato production has decreased during recent decades, while there has been a significant increase in the production of carrots, bulb onions, and other root vegetables. The industries handling potato and vegetables from domestic production and imported potato and root vegetables are located in most agricultural regions of Norway. The assessment deals with both quarantine pests and potential quarantine pests. In total 13 plant pathogenic viruses, five plant pathogenic bacteria and phytoplasmas, five plant pathogenic fungi, six plant parasitic nematodes and four plant parasitic insects have the potential for dispersal with waste from packing plants.
