Assessment of selenium in poultry food, chicken, eggs and their potential human health risks in Khyber Pakhtunkhwa, Pakistan

This study investigated selenium (Se) levels in poultry feed, chicken (meat and bones), and eggs in Khyber Pakhtunkhwa Province (Pakistan) using inductively coupled plasma mass spectrometry. Selenium levels in all poultry feed, meat, bone, and egg samples were below the permissible limit of 500 µg kg−1 set by the European Food Safety Authority. Selenium level was highest in bones (362 µg kg−1), followed by eggs (150 µg kg−1), feed (96 µg kg−1), and meat (59 µg kg−1). Selenium level differed significantly (P
