Ground venison packets from shotgun- and archery-harvested White-tailed Deer in Illinois in 2013 and 2014 were analyzed for metal contamination. Radiographs indicated that 48% of 27 ground venison packets from 10 shotgun-harvested deer contained metal fragments, while none of the 15 packets from three archery-harvested deer contained fragments. ICP-MS analysis verified that all metal fragments from seven of the venison samples from shotgun-harvested deer were composed of lead, with average concentrations from 1.04 to 8.42 μg g⁻¹, dry weight. A single serving of ground venison containing one of these metal fragments embedded in it would be predicted to have a lead concentration ranging from 6.4 to 51.8 μg g⁻¹. Sixty percent of 20 commercial meat processing plants surveyed by phone in 2018 and 2019 indicated that they mixed venison from multiple deer when preparing ground venison products. However, our results do not show any cross-contamination in archery-harvested ground venison processed prior to the firearm hunting seasons.

分析了2013年和2014年伊利诺伊州猎枪和射箭收获的白尾鹿的鹿肉包的金属污染情况。射线照片表明，来自10枚shot弹枪猎鹿的27袋鹿肉中有48％含有金属碎片，而来自3枚射箭猎鹿的15包中没有任何碎片。ICP-MS分析证实，来自shot弹枪捕获的鹿的七个鹿肉样品中的所有金属碎片均由铅组成，平均浓度为干重1.04至8.42μgg ^-1。预计其中一份嵌入其中的金属碎片之一的地面鹿肉的铅浓度范围为6.4至51.8μgg ^-1。在2018年和2019年通过电话调查的20家商业肉类加工厂中，有60％表示在准备地面鹿肉产品时它们将多头鹿的鹿肉混合在一起。但是，我们的结果并未显示在枪支狩猎季节之前加工过的射箭收获的鹿肉中有任何交叉污染。
