UK and EU regulators are evaluating the potential health benefits of restricting the use of lead ammunition. Little information is available on exposure of pets to ammunition-derived dietary lead from petfood containing meat from wild-shot game animals. We found dogfood including wild-shot pheasant meat to be widely available in the UK. 77% of samples from three raw pheasant dogfood products exceeded the EU maximum residue level (MRL) for lead in animal feed, with mean concentrations approximately 245, 135 and 49 times above the MRL. Concentrations > MRL were also found in a dried food containing pheasant, but not in a processed food, nor in chicken-based products. Lead concentrations in raw pheasant dogfood considerably exceeded those in pheasant meat sold for human consumption, possibly because the dogfood mincing process further fragmented lead particles from shot. Dogs frequently consuming such high-lead food risk adverse health effects; this should be considered within decision-making processes about regulation.
英国和欧盟监管机构正在评估限制使用含铅弹药的潜在健康益处。关于宠物通过食用含有来自野生动物的肉类的宠物食品摄入弹药衍生膳食铅的情况,信息有限。我们发现含有野禽肉的狗粮在英国广泛供应。三种生雉鸡狗粮产品中有 77%的样本的铅含量超过了欧盟动物饲料中铅的最大残留限量(MRL),其平均浓度约为 MRL 的 245、135 和 49 倍。在一种含有雉鸡的干燥食品中也发现了浓度超过 MRL 的铅,但在加工食品和以鸡肉为基础的产品中没有发现。生雉鸡狗粮中的铅浓度远远超过了供人类食用的雉鸡肉中的铅浓度,这可能是因为狗粮的绞碎过程进一步使来自弹丸的铅颗粒破碎。经常食用这种高铅食物的狗可能会有不良的健康影响;这应该在关于监管的决策过程中加以考虑。
