| Abstract | ||
| Aflatoxins are toxic metabolites found m foods and feeds. Aflatoxin M, (AFM,) appears in milk as direct result of the intake of Anatoxin B, (AFB,) contaminated feed by dairy cows. Our aim was te carry out a study to determine the incidence of AFM, and AFBI in milk collected from farms and supermarkets in Mansoura -Egypt. 130 different milk samples were collected of which 25 samples of Buffalo's raw milk and 25 of Cow's raw milk during winter 2002·2003 . 80 another milk samples were collected from supermarkets. The samples were analyzed for the presence of aflatoxins AFM, and AFB,. All samples were examined as duplicates by liquid chromatography mass spectrometry ( LC·MS ). The averaged concentration of AFM, was 0.288 ppb for buffalo's raw milk samples, and 0.312 ppb for cow's raw milk samples. One sample of Cow's milk out of twenty five contained above the maximum permissible limit of 0.5 ppb. Baby's milk, Butter milk, Dried whole milk and ultra high temperature milk (U.H.T) were completely free from anatoxin M, and AFB, On the other hand, all samples were fornd to be free from anatoxin B,. except for one out of ten samples of Buffalo's milk, powdered milk anc skim milk. All tested samples did not exceed the permissible limit of AFB,. In all cases, AFM, and AFB, levels were lower than the limit recommended for dairy products. | ||
