Determination of aflatoxin in milk and milk products producted in aydın and district

SUMMARYDetermination of Aflatoxin M1 in milk and milk products producted in Aydın anddistrict.Aflatoxins have been important relatively carcinogenic and teratogenic effect and toxicmetabolite in food and feedstuff of funguses as Aspergillus flavus, A. Parasiticus and A.Nomius. However, the toxins most important are B1, B2, G1, G2 and M1, M2. Aflatoxin M1(AFM1) is produced a metabolit excreted milk of most toxic aflatoxin B1 (AFB1). AflatoxinM1 is a very potent liver carcinogen. Aflatoxin M1 is appear milk products as milk, cheese,yoghurt, milk powder and butter for excreteed milk after aflatoksin B1 contaminates feedstuffare feed by lactating animals. Milk and milk product is important relatively amounts AFM1this crops since these products are consumed largely by persons as especially infants,children, suckle of mothers, olds. Therefore, many countres and Turkey have been dischargedvarious researched determine and reduce the least risk concentrations in presence of AFM1 inmilk and milk products.Aflatoxin presence in feed, milk and dairy products can be systemically controlled inEurope and other developed countries. In contrast, there is practically not enough controlsystem on the contamination of milk, dairy products and feed with AFM1 and AFB1 inTurkey. According to WHO and FAO regulation the content of AFB1 should be less than 0.05µg/kg in milk.In this study, AFM1 levels were determined by HPLC (High performance liquidchromatography) in milk and milk products samples collected in dairy farms from Aydın anddistrict.For this purpose, 47 samples consisted of milk (13), white cheese (7), kashar cheese (6),tulum cheese (6), curd chesee (6) and yoghurt (9) which were collected from 26 dairy farmswere examined. The determined mean result of aflatoxin M1 analysis was 0,105 pbb ofanalysed samples and the incidence of AFM1 was 100 % and the range was 0,027-0,250pbb. The analysed 61,5 % of milk samples, 77,7 % of yoghurt samples and 4 % of cheesesamples were exceeded the maximum legal limits.These results of the study confirm that milk and milk products producted in Aydın anddistrict may cause health problems. Milk and milk products have to be monitored continuously for thepresence of AFM1 contamination. AFB1 occuring conditions in the feeds of dairy animals and AFB1existence must be controlled strictly.
