Lysenko et al. 2021 - Organic Broiler Meat Heavy Metals
Lysenko et al. studied Hubbard Redbro broilers under different housing and feed conditions and measured arsenic, cadmium, mercury, and lead in pectoral and leg muscles. The paper is direct poultry occurrence evidence, but because it is an intervention/feed comparison, it should route with feed-regime context.
Key numbers
Table 5 reports heavy metals in poultry meat in mg/kg. In pectoral muscle, the first control group had As 0.0085547, Cd 0.0042257, Hg 0.0003421, and Pb 0.0247331. The first experimental group had Cd 0.0013512 and Pb 0.00176436, with As and Hg not detected. In leg muscles, control values included As 0.0066432, Cd 0.0035253, Hg 0.0003035, and Pb 0.0035317; experimental-group leg muscle had As, Cd, and Hg not detected and Pb 0.00063637.
Methods (brief)
The authors measured toxic elements in factory feed, farm-produced eco-feed, pectoral muscle, and leg muscle. They compared floor/cage housing and feed regimes.
Implications
This source supports poultry product context for low-level As, Cd, Hg, and Pb under Russian broiler feed/housing conditions. It should not be pooled as ordinary retail-market poultry without noting the experimental feed design.
