Alam et al. 2021 - Poultry Feed and Meat Contaminants in Bangladesh
Alam et al. tested broiler feed and meat for antibiotic residues, aflatoxin, and heavy metals in Bangladesh. The metal findings are direct poultry occurrence evidence, with a notable caveat: in meat, Cd and Cr were detected in only one of sixty samples, while lead was not detected.
Key numbers
For feed, mean concentrations were Cd 0.04 mg/kg, Pb 1.28 mg/kg, and Cr 2.55 mg/kg. Out of 60 broiler meat samples, one sample was positive for Cd at 56.41 mg/kg and Cr at 14.44 mg/kg; Pb was not detected in any meat sample.
Methods (brief)
The study collected 94 broiler feed samples and 60 broiler meat samples. Heavy metals were tested as part of a broader residue and toxin survey; thigh and breast muscles from 5-6 week broilers were used for meat sampling.
Implications
This source is useful for poultry-product gap filling in Bangladesh, but the meat results should be treated carefully because the extreme Cd and Cr values occurred in a single positive meat sample. The paper does not provide arsenic meat values in the routeable table.
