Detection of aflatoxin M1 in raw and imported powdered milk Sold in Khartoum State, Sudan

Aflatoxins are toxic fungal metabolites found in foods and feeds. When ruminants take Aflatoxin B1 (AFB1) - contaminated feedstuffs, they metabolize the toxin and excrete AFM1 in milk. The aim of the study was to determine the level of contamination of aflatoxin M1 (AFM1) in raw and imported powdered milk in Khartoum State, Sudan. Thirty five cattle milk samples were collected from different farms, selected on the base of type of concentrated feed introduced to the dairy cows and size of the farm. Twelve samples of powdered milk were obtained from repackaging companies in Khartoum State. The samples were analyzed by Flurometer, using Vicam method. The presence of AFM1 contamination was detected in all raw and powdered milk samples. Almost 50% of contaminated powdered milk samples and all the raw milk samples (100%) exceeded the European Communities/ Codex Alimentarius recommended limits (0.05μg/kg), while 33% of contaminated powdered milk samples and 77% of the raw milk samples exceeded the prescribed limits of US regulations (0.5μg/kg). There were significant (P
