据欧盟食品安全局（EFSA）消息，7月31日欧盟食品安全局发布了两年期全食（whole food）喂养研究的指导原则，评估长期食用全食对人体构成的癌症与毒性风险。欧盟食品安全局表示，这项指导原则有助于建立两年期食品与饲料致癌性和慢性毒性研究体系。
部分原文报道如下：
The European Commission asked EFSA to develop these guiding principles after noting that no guidance existed on conducting two-year feeding studies to assess the safety of whole food. It was agreed that the Authority would assess the extent to which established guidance currently used to evaluate the safety of individual chemical substances could be applied to whole food testing. EFSA identified testing guidelines （TG） 453 from the Organisation for Economic Co-operation and Development （OECD） as the best framework document for this purpose. In its scientific report, the Authority evaluates the suitability of this internationally-agreed test method to provide information on potential toxic or carcinogenic effects linked to the long-term consumption of an individual whole food. When formulating its guiding principles EFSA also considered the views of experts from EU Member States, who were consulted through the Scientific Network for the Risk Assessment of GMOs.
