Abstract

Foodborne exposure to chemical contaminants, such as melamine, remains a public health concern, particularly in developing countries. This study aimed to determine melamine concentrations in various retail egg products (local, industrial, liquid pasteurized eggs, and egg white powder) marketed in Ilam, western Iran, and to assess the associated non‑carcinogenic health risks. Samples were analyzed via high-performance liquid chromatography with UV detection, and method performance was verified by limit of detection, limit of quantification, and recovery. All samples had melamine below the EU limit (2.5 mg/kg), with the highest mean in local eggs (1.39 ± 0.19 mg/kg) and the lowest in egg white powder (0.46 ± 0.38 mg/kg); 39% exceeded 1 mg/kg. A probabilistic exposure assessment using Monte Carlo simulation indicated estimated daily intakes below the tolerable daily intake, with hazard quotients <1, suggesting no significant risk. Enhanced feed quality control and monitoring are recommended. Copyright © 2026. Published by Elsevier B.V.
