Ezike et al. 2024 - Arsenic, lead, and cadmium in Nigerian poultry products
This study measured arsenic, lead, and cadmium in Nigerian poultry meat and egg fractions alongside antibiotic residues. It is routeable for poultry and egg occurrence evidence because it reports metal ranges and matrix-specific means.
Key numbers
- The study analyzed 36 poultry product samples, including broiler muscle, gizzard, yolk, and albumen.
- Arsenic ranged from 0.0403 to 0.5970 mg/kg.
- Lead ranged from 0.2500 to 0.6670 mg/kg.
- Cadmium ranged from 0.0017 to 0.0672 mg/kg.
- The abstract reports As and Pb above the authors’ safe-limit comparisons in all samples, while Cd was within the cited safe limit.
- In the results narrative, muscle had the lowest As concentration at 0.0403 +/- 0.0038 mg/kg and yolk had 0.1213 +/- 0.0025 mg/kg.
- The albumen had the highest Cd concentration, 0.0672 +/- 0.014 mg/kg.
Methods
Samples were digested, Pb and Cd were measured by atomic absorption spectrometry, and As was measured by a UV-visible spectrophotometric method. Antibiotic residues were analyzed separately by HPLC.
Implications
The source supports Nigerian-market poultry and egg occurrence evidence for total arsenic, lead, and cadmium. It should be kept jurisdiction-specific and not pooled silently with US poultry data.

Verification notes
The title uses “potentially toxic ingredients” where the paper means potentially toxic elements. This page records the measured elements and avoids using the title phrase as a taxonomy term.
