This study assessed the quantitative microbial risk of non-enterohemorrhagic Escherichia coli (EHEC). For hazard identification, hazards of non-EHEC E. coli in natural and processed cheeses were identified by research papers. Regarding exposure assessment, non-EHEC E. coli cell counts in cheese were enumerated, and the developed predictive models were used to describe the fates of non-EHEC E. coli strains in cheese during distribution and storage. In addition, data on the amounts and frequency of cheese consumption were collected from the research report of the Ministry of Food and Drug Safety. For hazard characterization, a doseresponse model for non-EHEC E. coli was used. Using the collected data, simulation models were constructed, using software @RISK to calculate the risk of illness per person per day. Non-EHEC E. coli cells in natural- (n=90) and processed-cheese samples (n=308) from factories and markets were not detected. Thus, we estimated the initial levels of contamination by Uniform distribution ${\times}$ Beta distribution, and the levels were -2.35 and -2.73 Log CFU/g for natural and processed cheese, respectively. The proposed predictive models described properly the fates of non-EHEC E. coli during distribution and storage of cheese. For hazard characterization, we used the Beta-Poisson model (${\alpha}=2.21{\times}10^{-1}$, $N_{50}=6.85{\times}10^7$). The results of risk characterization for non-EHEC E. coli in natural and processed cheese were $1.36{\times}10^{-7}$ and $2.12{\times}10^{-10}$ (the mean probability of illness per person per day), respectively. These results indicate that the risk of non-EHEC E. coli foodborne illness can be considered low in present conditions.

Cheese consumption has been gradually increased in China. However, both the manufacturing process of cheese and the utilization of its main by-product were not well developed. Based on the sensory evaluation, Box-Behnken Design (BBD) was performed in the present study to optimize the cheese processing, which was proved more suitable for Chinese. The optimal parameters were: rennet 0.052 g/L, start culture 0.025 g/L and $CaCl_2$ 0.1 g/L. The composition analysis of fresh bovine milk and whey showed that whey contained most of the soluble nutrients of milk, which indicated that whey was a potential resource of cyclic adenosine-3', 5'-monophosphate (cAMP). Thus, the cAMP was isolated from whey, the results of high-performance liquid chromatography (HPLC) analysis showed that the macroporous adsorption resins (MAR) D290 could increase the concentration of cAMP from $0.058{\mu}mol/mL$ to $0.095{\mu}mol/mL$. We firstly purified the cAMP from the whey, which could become a new source of cAMP.

Milk and milk products, especially the cow's milk and cheese, have been used since the ancient time. Because they contains almost all kinds of nutrients that are necessary for human beings except for iron, n-3 fatty acid, and vitamin C. Milk is an excellent dietary source of protein, calcium and phosphorus. The biological value of milk protein is as high as those of red meat and eggs. So cheese, a food processed from concentrated milk protein, is highly recommended food for the patient of diabetes mellitus. Because the major form of milk lipids is n-6 fatty acid, milk and milk products may not be a good food for the patients of cardiovascular disease. But the nutritional quality of milk lipids cannot be inferior to those of margarine, fish oil, and vegetable oil. Milk has been produced commercially since 1936 in Korea. The most popular milk product is a drink milk now in Korea. But according to the change of dietary pattern the consumption of yoghurt and cheese has been enormously increased during the last 20 years. As the soy sauce, tofu, and soy been paste have been the fundamental seasoning and source of protein in Korea, milk and cheese have consisted the essential flavor of western cuisine. But the basic idea for the usage of protein, peptides, and amino acids are the same. We found that milk and milk products can be nicely added in many Korean dishes such as Juk, Mandoo, Jeon, and Bindeatuk for the diversity of traditional flavor.

The consumption of natural cheese in Korea has dramatically increased since 1997. However, most of the cheeses consumed in Korea are imported. Thus, surplus milk has accumulated in Korea. To solve this problem, the Ministry of Agriculture, Food and Rural Affairs established a policy to create a farmstead dairy industry. Although the law governing the industry was established in 2016, food safety guidelines have not been prepared. Milk and cheese are prone to contamination with mycotoxins such as aflatoxin M1 and ochratoxin A, antibiotic residues such as penicillin and tetracycline, and pathogenic bacteria including Listeria monocytogenes, Escherichia coli, Salmonella, and Staphylococcus aureus. L. monocytogenes infections have a very high mortality rate; hence, special attention should be paid to preventing contamination of milk and cheese with this organism. To ensure the microbiological safety of farmstead dairy products, the HACCP model has been used. However, this model is not suitable for current processing environments of farmstead dairy products because of the small size of the operations. In addition, scientific data on the microbiological safety of farmstead dairy product are limited and are urgently needed.

In the time period 1996-2004, all incident cases of bladder cancer were included in a case-control study in order to study the role of meat consumption and product animals in the etiology of urothelial cancer. The study included 225 cases and 1,510 hospitalized controls with non-neoplastic conditions, not related to smoking and alcohol drinking. Relative risks, approximated by the odds ratios, were calculated in order to clarify the effect of meat consumption in the etiology of urothelial cancer. Total meat consumption (OR 1.47, 95% CI 1.02-2.11), total processed meat (OR 1.57, 95% CI 1.08-2.27), frankfurters (hot dogs) (OR 2.03, 95% CI 1.28-3.21), ham (OR 1.79, 95% CI 1.21-2.67) and salted meat (OR 2.73, 95% CI 1.78-4.18) were positively associated with risk of bladder cancer. Animal products, like cheese, whole milk, and total eggs were also associated with bladder cancer risk (OR for eggs 4.05, 95% CI 2.68-6.12). In conclusion, total meat, processed meat, and eggs could play an important role in the etiology of bladder cancer in Uruguay.

A total of 100 adults were surveyed on types of favorable meat products. They tended to show much of unsatisfactory on the market products. Those unsatisfactory were mostly conceptual such as instant products, unreliable raw materials, sanitation conditions, list of unfavorable ingredients, mix of harmful additives, and etc. The results indicated that the consumers purchased the products of ham, cheese, chicken, sausages, and canned products mostly at medium-large marts(56%), department stores(22%), retail stores(19%) and others(3%). They were also concerned with the distribution date, prices, shape of packaging, and etc. The types of products and frequencies of purchasing various products were varied by time. For the purchase of products, mixed items were more favored rather than the single items.

The purpose of this study was to investigate the nutrition knowledge, perception, and intake frequency of milk and milk products among middle school students as well as provide the basic data needed for increasing milk and milk product consumption. To achieve the purpose of this study, a survey with 385 students of four middle schools located in Chuncheon was conducted. The level of nutrition knowledge of milk and milk products in females was slightly higher than that in males (p<0.01). Flavored milk and ice cream were preferred the most in each category, and 'taste' influenced the selection of milk and milk products the most. The intake frequency of whole milk was the highest, and that of flavored milk was lowest among various milks. Ice cream showed the highest intake frequency while cheese showed the lowest among milk products. Male students showed higher intake frequency of milk and milk products. Groups having high level of nutrition knowledge showed the highest intake of whole milk, whereas groups having a low level of nutrition knowledge preferred processed milk, low fat or non-fat milk, and cheese the lowest.

Dairy goat production continues to be a socially, economically and culturally important part of the livestock industry in North, Central and South America and the Caribbean islands. Goat milk, cheese and other dairy products offer consumers food products with nutritional, health and environmental benefits. In North America, Mexico produces the greatest volume of goat milk, but most is for family or local consumption that is typical of a mixed farming system adopted by subsistence farmers in dry areas. The United States is not yet a large global goat milk producer, but the sector has expanded rapidly, with dairy goat numbers doubling between 1997 and 2012. The number of dairy goats has also increased dramatically in Canada. Commercial farms are increasingly important, driven by rising demand for good quality and locally sourced goat cheese. In South America, Brazil has the most developed dairy goat industry that includes government assistance to small-scale producers and low-income households. As of 2017, FAO identified Haiti, Peru, Jamaica, and Bolivia as having important goat milk production in the Western Hemisphere. For subsistence goat producers in the Americas on marginal land without prior history of chemical usage, organic dairy goat production can be a viable alternative for income generation, with sufficient transportation, sanitation and marketing initiatives. Production efficiency, greenhouse gas emission, waste disposal, and animal welfare are important challenges for dairy goat producers in the Americas.

The aim of this review is to show the evolution of the dairy goat sector in Europe from all perspectives. Starting from the current situation, the challenges and future potential of this livestock system are presented, as well as strategies to overcome the difficulties faced. Europe holds 1.9% of the world goat population and produces 15.1% of goat milk recorded worldwide. The goat species plays a fundamental economic, social and environmental role in many regions of Europe. The wide diversity of production systems and autochthonous breeds makes the sector very heterogeneous. In order to improve viability, a number of strategies need to be adopted to solve the current problems such as a low profitability, absence of generational change and a little or no recognition of the social and environmental role of the sector. Some strategies to improve the situation of the European goat sector include: i) generating market value that will recognise the diversity of the dairy goat sector (breeds, feeding models, derived products${\ldots}$); ii) promoting and raising awareness of the functional attributes of goat milk and derived products so as to increase consumption; iii) assigning an economic value to environmental and social functions; iv) improving working conditions through technological innovation to make goat farming more attractive to young people; and v) processing more milk into cheese or other dairy products in production areas.

In this study, we achieve an increase in sales of dairy companies through innovation in the distribution process of developing core competencies through product differentiation in the domestic dairy companies, creating new consumption pioneered new markets. First of all, improving the quality of milk in the premium milk market can be able to expect the activation of consumption and through promotion activities by the Korean wave can lead to create new consumption pioneered the market diversification at the same time export varieties of white milk and jersey species take advantage of a variety of milk in addition to drink beauty and cooking areas while lowering manufacturing costs through the introduction of the cheese will increase the revenue of the dairy companies and dairy consumption expected to activate at the same time. It is necessary to change cultivars in order to think about nutritional value and flavor, and further environment, and high quality premium milk will become a new trend in the future. Furthermore, promoting the benefits of milk consumption would contribute in raising the milk demand that is negatively correlated with increasing age.
