Disturbed by reports of high concentrations of cadmium in large land mammals in Arctic Canada, community members wondered if they should eat less moose (Alces alces).
Risk assessment modelling.
We measured cadmium concentrations in moose tissues donated by food hunters. As a conservative assumption, we took the upper limits of the 95% confidence intervals for the means. Cadmium intake from other sources we estimated using risk assessment models. Assuming a Tolerable Daily Intake of cadmium of 1 microgram per kg body weight per day, we calculated maximum allowable intakes of moose kidney, liver and muscle.
For a non-smoking 70 kg adult, allowable monthly intakes are: 52 kg of moose muscle, or 137 g of kidney, or 516 g of liver. Allowable intakes varied by age and in proportion to body weight. Cigarette smokers (one to 1.5 packs per day) reach the limit even if they consume no moose at all.
Adults may continue to eat moose kidney and liver occasionally and in moderate amounts, but children and cigarette smokers should not eat these organs at all. Consumption of moose muscle need not be restricted. Monitoring of cadmium concentrations in moose should continue.
加拿大北极地区大型陆地哺乳动物体内镉含量高的报道引起了社区成员的担忧，他们想知道自己是否应该少吃驼鹿肉（驼鹿属）。
风险评估建模。
我们测量了由猎食者捐赠的驼鹿组织中的镉含量。作为保守假设，我们采用了均值95%置信区间的上限。我们使用风险评估模型估算了其他来源的镉摄入量。假设镉的每日耐受摄入量为每千克体重1微克，我们计算了驼鹿肾、肝和肌肉的最大允许摄入量。
对于一名体重70千克的不吸烟成年人，每月允许摄入量为：52千克驼鹿肉、137克肾或516克肝。允许摄入量因年龄而异，并与体重成比例。每天吸1至1.5包烟的吸烟者即使完全不吃驼鹿肉也会达到限量。
成年人偶尔可适量食用驼鹿肾和肝，但儿童和吸烟者应完全避免食用这些器官。驼鹿肉的食用无需限制。应继续监测驼鹿体内的镉含量。
