Investigation for contaminations of raw milk on milk collection units in Nevsehir province

Abstract

In this study, it was aimed to investigate Aflatoxin M1 and heavy metal pollution in raw milk samples taken from milk collection centers operating in Nevsehir province. As a result of the analyzes made on raw milk samples; The amount of Aflatoxin M1 was determined in the range of 0.013-0.150 ppb, in 7 raw milk samples remained below the measurement limit. A limit of 0.05 ppb has been determined for Aflatoxin M1 in the Turkish Food Codex and the amount of Aflatoxin M1 was determined above the legal limit in 15% of the raw milk samples taken. As a result of heavy metal analysis with ICP-MS in raw milk samples, Mg 41,96±1,88 ppm; Ca 79,83±4,30 ppm; Mn 0,0115±0,007 ppm; Fe 0,176±0,003 ppm; Ni 0,0283±0,002 ppm; Cu 0,0181±0,003 ppm; Zn 1,56±0,005 ppm; As 0,0046±0,000 ppm; Cd 0,001549±0,002 ppm and Pb 0,00048±0,000 ppm were found, respectively. According to our study results, it was determined that there was no risk human health risk in terms of heavy metal.
