Contrary to the safe practices of milk pasteurization or sterilization, which effectively reduce foodborne outbreaks incidence associated with raw milk and dairy products use, outbreaks caused by such products continue to occur. Despite this fact, a worldwide movement advocating for the rights of raw milk and cheese selling and consumption, due to their specific nutritive characteristics, has strengthened significantly in recent years. Traditional agricultural manufacturers from Serbia still sell products related to thermally unprocessed milk, such as cottage cheese and raw cream. In AP Vojvodina during the period of 1981-2010 a total of 179 foodborne outbreaks were reported, where the incriminated cause of the outbreak were milk or diary. In 126 (70.39%) outbreaks, totaling 2276 sick individuals and one casualty, it was confirmed that the incriminated food was from the group of dairy products. In 48 instances (26.82%), bacteriological tests confirmed that milk and dairy products were excluded as the outbreak causes, while in another 5 (2.79%) outbreaks, microbiological analysis of food failed to confirm any relation to the actual epidemiological instances. In some cases, bacteriological testing of incriminated foods was not possible. In the cases of outbreaks associated with the consumption of milk and dairy products, traditional raw milk products were cited as being used. Consumption of unpasteurized milk and cheese represents public health threat. National and international rules ensuring use of safe products for human consumption have to set rules of trade of thermally processed milk and products on the market.

     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.

Examination of 227 samples of milk and dairy products for Listeria monocytogenes showed that raw milk and some Moroccan traditionally made dairy products such as Iben and raib (fermented milks) and jben (fresh cheese) were contaminated with this pathogen. L. monocytogenes was the only Listeria species isolated except in one case in which it was associated with Listeria innocua. Pasteurized milk, fresh cream, and fresh and ripened cheeses (industrially made) were free from L. monocytogenes.

A total of 163 samples of milk and milk products (including raw milk, Damietta and Kareish cheese, hard and processed cheese, yogurt, butter and ice cream) were collected from Assiut City markets. Clostridium perfringens was detected in 45.5, 20, 30, 14.3, 20, 10, 50 and 20% of the examined samples, respectively, using SPS agar. With TSN agar, the organism was isolated from 72.7, 20, 30, 28.6, 50, 10, 50, and 30% of the samples, respectively. The mean value of the C. perfringens count using SPS agar was 53.6/ml, 40/g, 60/g, 14.3/g, 30/g, 1.4/g, 25/g and 8/ml of raw milk, Damietta and Kareish cheese, hard and processed cheese, yogurt, butter and ice cream samples, respectively, while the mean values of C. perfringens counts obtained with TSN agar were 76.4/ml, 170/g, 140/g, 42.9/g, 590/g, 2.9/g, 172.9/g, and 109/ml of examined samples, respectively. Milk and dairy products, if improperly handled, provide a means for transmission of C. perfringens to the consumer.

Now, along with the improvement of people's living standard, more and more people quality safety problems of dairy products by the attention. Milk quality index basically has sensory indexes and physiochemical index, microbiological quality and harmful material residues and pollutants quantity four aspects. Regarding the enterprise, it wants to produce milk, besides should assured teaches defend in production of various indexes; outside the control of raw also cannot be ignored. The key points to control of raw comparison of raw index are to ensure effective method.In recent years, as environmental pollution increasingly heavier, antibiotics, making the wrong use already slowly pollution to harmful material variety of dairy products, in the milk antibiotic and heavy metal content has become the focus of people are indexes. First, in this paper introduces dairy products can exist of antibiotic types and the detection method, then to mercury as example, the paper introduces the current national state currently can several methods of determination of mercury, through the practical consideration, find a relatively simple, efficient, feasibility big test methods.
