Breast muscle samples, with or without overlying adipose tissue and skin, were obtained from Canada geese collected in northeastern illinois while undergoing feather molt. Specimens were evaluated for contaminant concentrations to determine if they would be acceptable as human food provided through government-subsidized programs. Samples were baked, allowing fat to drip free, and assayed for persistent organochlorine pesticides and polychlorinated biphenyls. Residues of heptachlor epoxide, dieldrin, DDE and PCBs (as Arochlor 1248) were detected. The specimens contained relatively low concentrations of contaminants, such that US Department of Agriculture residue limits for meat were exceeded in only 1 sample. Baking of breast muscle without the overlying skin and adipose tissue resulted in reductions in concentrations of detectable compounds. Fewer samples baked with the skin attached had detectable concentrations of heptachlor epoxide, dieldrin and PCB then samples cooked without skin; however, the converse was true for DDE. Periodic monitoring for environmental contaminants such as PCBs, exclusion of geese from localities where samples have contaminants such as PCBs, exclusion of geese from localities where samples have contaminants at concentrations that exceed recommended dietary limits, the use of processing and/or cooking methods which remove large amounts of lipid, and advisories that provide information on known health risks are recommended if wild resident Canada geese from the Chicago area are provided as food for underprivileged humans.
从伊利诺伊州东北部收集的正在换羽的加拿大鹅身上获取胸肌样本，样本带有或不带有上层脂肪组织和皮肤。对样本进行污染物浓度评估，以确定其是否适合作为政府补贴项目提供的人类食物。样本经过烘焙，使脂肪滴尽，然后检测其中的持久性有机氯农药和多氯联苯。检测到七氯环氧化物、狄氏剂、滴滴伊和多氯联苯（以氯丹1248计）的残留。样本中的污染物浓度相对较低，只有1个样本超过了美国农业部规定的肉类残留限量。烘焙不带上层皮肤和脂肪组织的胸肌会使可检测化合物的浓度降低。带皮烘焙的样本中，七氯环氧化物、狄氏剂和多氯联苯的可检测浓度低于去皮烘焙的样本；然而，滴滴伊的情况则相反。如果将芝加哥地区的野生加拿大鹅作为贫困人群的食物，建议定期监测多氯联苯等环境污染物，将鹅排除在样本含有多氯联苯等污染物的地区，将鹅排除在样本污染物浓度超过推荐膳食限量的地区，采用能去除大量脂质的加工和/或烹饪方法，并发布有关已知健康风险的建议。
