Abstract A new method is described for the determination of aflatoxin M, in milk and dairy products by thin layer chromatography. The main characteristic is the extraction system using an alkaline solution. Lipids are removed by centrifuging at low temperatures, and the aflatoxins are then extracted with CHC13. The method has 2 options: Technique II (detection limit 0.02 ppb) requires cleanup on a chromatographic column; this is not necessary in Technique I (detection limit 0.1 ppb). The recovery rate in both techniques is over 92.8% in milk and yoghurt. This method may also be used for other aflatoxins. Because of the advantages of the method, Technique II is recommended for aflatoxin M1, control in milk, where a low detection limit is necessary. Technique I is proposed for experimental aflatoxin production studies in dairy products, which require analysis of a large number of samples but which do not require a very low detection limit.

Aflatoxin M1 is a highly toxic 4-hydroxylated metabolite of aflatoxins B1 and B2. It is one of the most potent hepatocarcinogens, mutagens, teratogens and immunosuppressors. Feed is often contaminated with aflatoxigenic moulds and aflatoxins with a high possibility of contaminating milk and dairy products with aflatoxin M1. Samples of artificially contaminated milk were exposed to the effects of physical conditions (temperature of -18oC and for microwaves in a microwave oven), time (during the period from 1 to 12 months) and a combination of the above mentioned conditions. Following this, levels of aflatoxin M1 degradation were established by using the ELISA method. An insignificant decrease in concentration of toxin was observed which indicates that a temperature of -18?C does not significantly influence the concentration of aflatoxin M1 in the artificially contaminated milk. At the same time, treatment of milk with microwaves in a microwave oven showed an insignificant influence on the percentage of aflatoxin M1 absorbance.

     Milk and dairy products are fundamental components in the human diet and may be the principle way for entrance of Aflatoxin M1 (AFM1) in to the human body. All milk and dairy products samples were tested for the occurrence of AFM1 by the competitive ELISA technique. Out of 32 bovine raw milk samples that were collected from eight villages around Baghdad province, 32 samples (100 %) were contaminated with AFM1 ranging from 0.15 to 86.96ng/kg with mean value of 42.37±26.07 ng/kg, of which 17 samples were contaminated with concentrations < 50 ng/kg and 15 samples exceeded the maximum acceptable level of AFM1 in milk (50 ng/kg) imposed by the European legislation. The raw milk samples belonged to animals fed with composite and stored fodder as in Althahab Alabiadh, Radhwaniya and Fadhaliya villages had higher significantly AFM1 concentrations over all the other five villages (Grazing feed). All 32 (100%) locally produced soft white cheese samples analyzed were contaminated with AFM1 ranging from 31.84 to 89.44 ng/kg with the mean value of 59.92±17.03 ng/kg. Out of 32 locally produced yoghurt samples analyzed, 32 samples (100%) were contaminated with AFM1 ranging from 0.16 to 42.74 ng/kg with the mean value of 16.92±11.55 ng/kg. Thirty samples (100%) of the examined 30 imported UHT milk samples that were collected from different commercial companies in the province of Baghdad presented significantly  high contamination level with AFM1 that were found to range from 0.18 to 85.66 ng/kg.

Aflatoxin M1 is a derivate of aflatoxin B1 and an important contaminant of milk and dairy products. This systematic review and meta-analysis was conducted on relevant Persian and English original articles in national and international databases with no time limits until 1 January 2018. In total 605 articles were found among which 70 articles met the inclusion criteria for meta-analysis. The prevalence (95% confidence interval (CI)) and mean concentration (95% CI) of aflatoxin M1 was found to be 64% (53-75%) and 39.7 ng/l (31.9-47.4 ng/l) in raw milk, 95% (89-98%) and 62.3 ng/l (40.6-84 ng/l) in pasteurised milk, 71% (56-84%) and 60.1 ng/l (30.9-89.3 ng/l) in sterilised milk, 59% (20-93%) and 5.5 ng/l (3.3-7.7 ng/l) in breast milk and 72% (61-81%) and 82.3 ng/kg (63.7-100.9 ng/kg) in dairy products. In general, 9% (4-16%) of milks and 10% (4-17%) of dairy products had aflatoxin M1 in concentrations exceeding the permitted level of Iranian standards (500 ng/l). Based on the maximum permitted aflatoxin M1 concentration in standards of Europe (50 ng/l), these percentages increase to 25% (18-32%) for milks and 18% (9-29%) for dairy products. According to the results, further control and preventive measures should be applied on livestock feeds because decreased aflatoxin B1 contamination at this level results in decreased aflatoxin M1 in milk and dairy products.
