EFSA News Story, 30 July 2010
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 [see Note 1 below] .
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 [see Note 2 below] . 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 [see Note 3 below] .
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.
 There are 209 types of PCBs. Based on their structure and toxicological effects, PCBs are divided into dioxin like PCBs (DL PCBs) and non dioxin-like PCBs (NDL PCBs).
