Overview
This Russian study measured 30 mineral elements in chilled broiler drumsticks from two poultry producers. It is routeable for poultry occurrence context because the edible chicken matrix was directly analyzed and the paper reports mg/kg concentrations for arsenic, cadmium, lead, chromium, nickel, tin, aluminum, and related elements.
Key numbers
Source units are mg/kg.
- Sample 1 broiler drumsticks: As 0.37 +/- 0.02; Cd 0.02 +/- 0.01; Cr 0.003 +/- 0.001; Pb 0.03 +/- 0.01; Al 5.86 +/- 0.40; Sn 0.69 +/- 0.04.
- Sample 2 broiler drumsticks: Cr 0.087 +/- 0.007; Ni 1.07 +/- 0.34; Pb 0.003 +/- 0.001; Sn 0.036 +/- 0.022; Sb 0.074 +/- 0.005; Al 71.55 +/- 6.61.
- The authors state that Sample 1 arsenic exceeded the poultry-meat maximum of 0.1 mg/kg by 3.7-fold; cadmium and lead were within applicable norms.
- The authors compare Sample 2 nickel with a literature value of 0.052 +/- 0.007 mg/kg in broiler thigh muscle and describe Sample 2 as 20.6-fold higher.
Methods
Mineral elements were quantified with an iCAP 7200 DUO inductively coupled plasma emission spectrometer. The study compared chilled broiler drumsticks from a Chelyabinsk-region producer and a Bashkortostan producer.
Implications
The paper supports poultry-meat occurrence context for Russian broiler drumsticks and preserves a clear producer/geography distinction. The values should not be pooled across broader poultry categories without retaining that two-sample limitation.
