X-ray screening of donated wild game is insufficient to protect children from lead exposure
2024
Arnemo, Jon
Worldwide hunters distribute game meat as a gesture of community bonding and as an essential nutritional resource for those facing food insecurity, especially among children and adolescents. Nonetheless, the risk of lead (Pb) contamination from lead-based bullets is not widely acknowledged. Although medical radiography (X-ray) is the standard method to detect lead in meat donations, its efficacy in conclusively identifying lead contamination in game meat samples remains unknown. To address this deficiency, hunters-provided game meat samples were analyzed using both X-ray and inductively-coupled plasma mass spectrometry (ICP-MS). By ICP-MS, 48% of these samples contained lead levels exceeding the daily intake benchmarks for children, including the samples in which no lead was identified by X-ray screening. This finding means that food insecure individuals need to make an unenviable decision between risking lead exposure in donated meat or forgoing a potentially critical food source.
