Toxic elements in eggs and egg-based products: occurrence, exposure assessment and risk characterisation for the Serbian population

This study aimed to assess the exposure of the Serbian adult population to As, Cd, Pb and Hg through the consumption of eggs and egg-based products and to assess health risks. Coccidiostat residues were also examined, and their contribution to acceptable daily intake was calculated. Egg samples were collected from 2018 to 2020. The consumption survey was conducted during 2020. A Monte Carlo simulation was performed to estimate the intake of toxic elements based on one-day and seven-day recalls of egg consumption. The results obtained showed that the adult population in Serbia is not exposed to health risks from the studied toxic elements when consuming eggs and egg-based products. The presence of anticoccidial agents was detected in 22% of egg samples at concentrations above the limits prescribed by current regulations in Serbia (which do not allow detectable levels of coccidiostats in eggs), with the main risk of exposure being to coccidiostat residues associated with maduramycin.

Automated summary

The study found that the adult population in Serbia is not exposed to health risks from toxic elements when consuming eggs and egg-based products. However, residues of anticoccidial agents were detected in some egg samples, with maduramycin posing the main risk of exposure.
