欧洲委员会要求EFSA植物健康小组对野油菜黄单胞菌致病变种进行有害生物分类。菜豆在得出结论时，评估小组认为四个参数在风险评估领域至关重要：（一）X的存在和分布;野油菜致病变种本报告的主要内容包括：（i）在风险评估区域内菜豆的危害及其传播潜力;（ii）主要寄主植物在整个欧洲联盟（EU）的存在和分布;（iii）对欧洲种植的作物造成损害的潜力;以及（iv）虫害控制战略和栽培措施的实施。以前被鉴定为X的生物。野油菜致病变种菜豆已被证明是遗传多样性的，目前被称为黄单胞菌褐色亚种。镰刀菌和轴足黄单胞菌致病变种（Xanthomonaxonopodispv.）菜豆根据其分析，专家小组得出结论，这些病原体的身份得到明确界定，其分布涉及欧盟的有限地区或区域，尽管不确定性中等。这些病原体的主要传播途径是污染的种子。此外，专家小组注意到，寄主植物在整个欧盟广泛种植，普通菜豆具有重要的商业价值，不仅用于新鲜、罐装、深冻和干燥的消费，而且用于种子工业。目前，由于种子测试，普通细菌性枯萎病在欧盟的影响有限。最后，专员小组得出结论认为，预计豆类在产量和质量损失方面将受到中度至高度的影响，特别是如果天气条件有利于病害和种子接种物不再含有的话。(C)欧洲食品安全局，2014年
The European Commission requested the EFSA Panel on Plant Health to perform a pest categorisation for Xanthomonas campestris pv. phaseoli. In reaching its conclusions, the Panel considered four parameters to be of critical importance in the risk assessment area: (i) the presence and distribution of X. campestris pv. phaseoli in the risk assessment area and its potential for spread; (ii) the existence and the distribution of the main host plants throughout the European Union (EU); (iii) the potential for damage to crops grown in Europe; and (iv) the implementation of pest control strategies and cultural measures. The organisms formerly identified as X. campestris pv. phaseoli have proven to be genetically diverse and are currently known as Xanthomonas fuscans subsp. fuscans and Xanthomonas axonopodis pv. phaseoli. Based on its analysis, the Panel concluded that the identity of these pathogens is clearly defined and their distribution involves limited areas or regions in the EU, although with a medium uncertainty. The main dispersal pathway for these pathogens is contaminated seeds. In addition, the Panel noted that host plants are widely cropped throughout the EU, common bean Phaseolus vulgaris being of great commercial importance, not only for consumption-fresh, canned, deep frozen and dried-but also for the seed industry. Currently, the impact of common bacterial blight is limited in the EU as a consequence of seed testing. Finally, the Panel concluded that moderate to high consequences, in terms of yield and quality losses, are expected for beans, especially if weather conditions are conducive to disease and seed inoculum no longer contained.
