食品伙伴網(wǎng)7月31日?qǐng)?bào)道，據(jù)歐盟食品安全局（EFSA）官網(wǎng)于7月30日發(fā)布的消息稱(chēng)，ESFA發(fā)表了有關(guān)食品和動(dòng)物飼料中的非二英類(lèi)多氯聯(lián)苯的含量報(bào)告。2002年，歐盟委員會(huì)發(fā)表了一份行動(dòng)清單，以減少二惡英和多氯聯(lián)苯在食品和飼料中的存在，并建議會(huì)員國(guó)監(jiān)察相關(guān)情況。這份報(bào)告是基于1999年到2008年，來(lái)自歐盟18個(gè)成員國(guó)及冰島和挪威和11214份食物樣品和1349份飼料樣品的的研究數(shù)據(jù)編寫(xiě)而成的，它是對(duì)之前的關(guān)于二英及二英類(lèi)多氯聯(lián)苯報(bào)告的后續(xù)。

     多氯聯(lián)苯（PCBs）是一種廣泛存在的于環(huán)境和人體中的難降解的有機(jī)化工產(chǎn)品。雖然上世紀(jì)80年代以來(lái)，大多數(shù)國(guó)家都停止了生產(chǎn)和使用PCBs，但電氣設(shè)備、塑料制品、建筑材料中仍大量含有。而且多氯聯(lián)苯可以被釋放到環(huán)境中，除了意外事故、職業(yè)接觸以外，人們接觸PCBs主要是通過(guò)食物途徑。國(guó)際癌癥研究機(jī)構(gòu)已把多氯聯(lián)苯列為可能致癌的物質(zhì)。

    在7月30日歐盟食品安全局發(fā)布的報(bào)告中稱(chēng)，污染程度最高的食品為魚(yú)及魚(yú)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。而在動(dòng)物飼料中，含有魚(yú)類(lèi)相關(guān)產(chǎn)品的污染最嚴(yán)重，例如魚(yú)油。

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.
