Mahbub et al. 2018 - Metals in poultry feed, meat, and eggs in Bangladesh
This study measured chromium, lead, and arsenic in poultry feed, meat, and egg samples from Bangladesh. It is useful for poultry and egg occurrence context because the paper reports meat and egg concentrations separately from feed values.
Key numbers
Source units are ppm, equivalent to mg/kg for these matrices.
- Chromium maxima: broiler meat 1.02; spent hen meat 6.36 with minimum 0.51; egg albumen 0.19 to 0.16; layer ready feed 1.98 to 0.03; loose layer feed 358.05 to 0.69; broiler ready feed 9.09 to 0.12; protein concentrate up to 1720.
- Lead maxima: egg albumen 3.34; egg yolk 0.51; whole egg 0.09; protein concentrate 30.27; layer ready feed 0.75; loose layer feed 0.86; broiler ready feed 0.69. The table text reports broiler, cockerel, and spent-hen meat as positive with trace/minimum fields but OCR does not preserve all meat maxima.
- Arsenic maxima: broiler meat 0.09; cockerel meat 0.02; spent hen meat 0.003; egg albumen 0.01; egg yolk 0.01; whole egg 0.004; layer ready feed 0.08; loose layer feed 0.07; broiler ready feed 0.03; protein concentrate 0.04.
- The authors state that 14% of broiler meat and 50% of spent-hen samples were slightly above the arsenic maximum permitted concentration used by the study.
Methods
Samples were dried, prepared, and analyzed for arsenic, lead, and chromium by AAS-based methods at the Bangladesh Livestock Research Institute laboratory.
Implications
The source supports poultry-meat and egg occurrence context for Bangladesh. Feed values explain a likely pathway but should remain separate from edible meat and egg values.

Verification notes
- Source identity checked against DOI 10.3329/aajfss.v2i1.55893 and the downloaded PDF.
- Feed values are not pooled with edible product values; the OCR preserved the arsenic meat maxima more clearly than the lead meat table.
