食品伙伴网7月31日报道，据欧盟食品安全局（EFSA）官网于7月30日发布的消息称，ESFA发表了有关食品和动物饲料中的非二英类多氯联苯的含量报告。2002年，欧盟委员会发表了一份行动清单，以减少二恶英和多氯联苯在食品和饲料中的存在，并建议会员国监察相关情况。这份报告是基于1999年到2008年，来自欧盟18个成员国及冰岛和挪威和11214份食物样品和1349份饲料样品的的研究数据编写而成的，它是对之前的关于二英及二英类多氯联苯报告的后续。

     多氯联苯（PCBs）是一种广泛存在的于环境和人体中的难降解的有机化工产品。虽然上世纪80年代以来，大多数国家都停止了生产和使用PCBs，但电气设备、塑料制品、建筑材料中仍大量含有。而且多氯联苯可以被释放到环境中，除了意外事故、职业接触以外，人们接触PCBs主要是通过食物途径。国际癌症研究机构已把多氯联苯列为可能致癌的物质。

    在7月30日欧盟食品安全局发布的报告中称，污染程度最高的食品为鱼及鱼肉制品，其次是原料奶及乳制品，蛋及蛋制品，在水果蔬菜中的污染水平最低。而在动物饲料中，含有鱼类相关产品的污染最严重，例如鱼油。
   
    欧盟食品安全局建议足够数量对每种食物和饲料进行连续的随机样本测试，以确保可以准确评估和监测多氯联苯在食品链中的存在。

The European Food Safety Authority (EFSA) has published a report on the levels of non dioxin-like polychlorinated biphenyls in food and animal feed. In 2002, the European Commission issued a list of actions to be taken to reduce the presence of dioxins and PCBs in food and feed and recommended that Member States monitor the situation.

The report, which was prepared by EFSA’s Data Collection and Exposure unit (DATEX), is based on a total of 11,214 food and 1,349 feed samples collected from 18 EU Member States, Iceland and Norway between 1999 and 2008. It follows a report on dioxins and dioxin-like PCBs published earlier this year[1] .

Polychlorinated biphenyls (PCBs) are a widespread class of persistent organic chemicals that accumulate in the environment and in humans. They are associated with a broad spectrum of health effects. Although the production and use of PCBs have been discontinued in most countries since the 1980s, large amounts remain in electrical equipment, plastic products and building materials.

PCBs can be released into the environment and people are exposed to them mainly through food, with the exception of specific cases of accidental or occupational exposure. The International Agency for Research on Cancer has classified PCBs as probably carcinogenic to humans[2] . EFSA’s Panel on Contaminants in the food chain carried out a risk assessment on the presence of non dioxin-like PCBs in feed and food in 2005[3] .

In the report published today, EFSA says that the highest contamination levels were found in several fish and fish products followed by animal products, such as raw milk, dairy products, eggs and egg products. The lowest levels were found in fruit and vegetables. Similarly, the highest levels of contamination in animal feed were found in feed containing fish derived products, such as fish oil.

EFSA recommends continuous random testing of a sufficient number of samples in each food and feed group in order to ensure accurate assessment and monitoring of the presence of PCBs in the food chain.
