Abstract Mycotoxins are natural contaminants produced by different fungal species. Their occurrence in food and feed poses a threat of human and animals. This threat is caused either by a direct contamination of food or by a carry-over of mycotoxins and their metabolites into milk after consuming of contaminated feed. To protect consumer health and to reduce economic losses, surveillance and control of mycotoxin in food and feed has become a major objective for producers, regulatory authorities and researches worldwide. This study was conducted to determine the occurrence of aflatoxin, ochratoxin and zearalenone in a total of 120 raw cow, buffalo, sheep and goat milk samples which were collected randomly from Mansoura City, Egypt by using Ultra High Performance Liquid chromatography (UHPLC). Concerning raw cow milk samples, all milk samples (100%) were contaminated with aflatoxin M1 in a range of 146.10 to 8547.70 ng/L with a mean value of 1609.69±460.43 ng/L. All examined raw cow milk samples were exceeding the permissible limits according to ER (1990) and EC (2006) limits while 15 (50%) samples were exceeding the US FDA (1996) permissible limit. In raw buffalo milk samples, 12 (40%) were AFM1 contaminated in a range of 187.30 to 4646.80 ng/L with a mean value of 1187.06±360.02 ng/L. All examined raw buffalo milk samples were exceeding the permissible limits according to ER (1990) and EC (2006) limits while 6 (50%) samples were exceeding the US FDA (1996) permissible limit. |
