LEVELS OF PERSISTENT ORGANIC POLLUTANTS IN HEN EGGS FROM VARIOUS HOUSING SYSTEMS IN FRANCE
Persistent Organic Pollutants are chemical substances that persist in the environment, bioaccumulate through the food chain and induce adverse effects on human health. The aim of this cross-sectional study was to assess the levels of POPs in hen eggs from various housing systems, including PCDD/Fs, PCBs and PBDEs. French flocks from 101 rearing systems were visited from May 2007 to August 2008 for sampling and questionnaire, including conventional cages, free-range, organic and home consumption systems. The mean POP levels in eggs were similar in free range or organic systems (0.24 and 0.22 pg.g-1 l.w. for PCDD/F-TEQ, 0.26 and 0.24 pg.g-1 l.w. for PBDE and 0.45 and 0.41 pg.g-1 l.w. for Total-TEQ, respectively). Concerning mean levels in eggs from conventional cages systems, lower PCDD/F-TEQ (0.13 pg.g-1 l.w.) and Total-TEQ (0.22 pg.g-1 l.w.) than those from outside systems were found, unlike for PBDE (0.33 pg.g-1 l.w.). Finally, POP levels for all professional systems remained below the statutory European limits. Most of home consumption produced eggs, which are not submitted to these regulatory limits, were found to have higher levels than tolerated for eggs destined for commerce.
