الملخص

Introduction: Aflatoxin M1 (AFM1) is a type of mycotoxin, which can be found in milk and dairy products. Contaminations with AFM1 occur during harvest, drying, and storage in high humidity and temperature conditions. It has a high carcinogenic potential, high level of genotoxic activity, causes stunted growth of children and immune suppression. The aim of study was to examine AFM1 presence and to compare the results with European codex (EC) limits in samples collected from Gaza strip. Methods: Samples (n=96) consisting of milk and milk-based products locally produced or imported were obtained randomly from farms and markets in Gaza Strip. The samples were transported in refrigerated containers (4°C) and stored at (-20°C) until analysis. AFM1 was determined by direct competitive ELISA technique. Analysis followed instructions of manufacturer for kit(MyBioSource, USA). Results: AFM1 was positive in the majority of samples. AFM1 in raw milk (93% of samples) recorded a range (0.09-0.53ppb), which exceeded EC limits. While synthetic liquid milk and chocolate synthetic liquid milk samples showed AFM1 in a percent of (86%) and all were exceeded the EC limits. And white cheese samples showed AFM1 in a percent of (71%) and all were above EC limits. Regarding labneh, yogurt, flavored yogurt AFM1 was positive, and exceeded EC limits in(60%) and (58%) of samples, respectively. All samples of butter and powdered milk had AFM1 above EC limits. In addition, imported samples of pasteurized, synthetic liquid milk, labneh, cheeseand powdered milk were analyzed and high percent of them were exceeded the EC limits. Conclusions: All the age groups including infants and children consumed daily milk and milk products. The results of this study are alarming. AFM1 levels should be controlled regularly in milk and dairy products to minimize the health hazard caused by AFM1. Agricultural and veterinary practices should be improved to control dairy cow's feed. Keywords: Aflatoxin M1, Dairy products, ELISA, EC, Palestine.
