title: Concentrations of trace elements [corrected] and organochlorines in Mutton bird (Puffinus griseus).
abstract: The Sooty Shearwater (Puffinus griseus, commonly known as Mutton bird) is a migratory wild seabird, annually harvested for food by certain native groups in New Zealand and Australia and in many parts of the world. The concentrations of 22 elements and several organochlorine pesticides [2,2-bis(chlorophenyl)-1,1,1-trichloroethane (DDT), its derivatives dichlorodiphenyldichloroethene (DDE) and dichlorodiphenyldichloroethane (DDD), aldrin, chlordane, dicofol, lindane, and methoxychlor] in Mutton bird were determined over two consecutive years to evaluate its safety for human consumption. Twenty bird carcasses were purchased in each of 2007 and 2008 from a local source. No significant year effect (P>0.05) was found in the following nine trace elements: Al, As, Cd, Co, Cr, Cu, Ni, Pb and Se. The concentrations of Hg, Li and Na were higher (P<0.05) in 2008 samples compared to 2007. The toxic trace elements (mg/kg wet weight) in all the samples were below the maximum residual level (MRL). The concentration of Fe, Ca and Se in Mutton bird was higher than that in domestic land animal meats reported in literature. The residual organochlorine concentrations were all below the recommended MRL. Thus Mutton bird meat is high in essential nutrient elements and of low toxicological risk. Due to active use of agrochemical in New Zealand, a monitoring program for contaminants in Mutton birds is recommended.
