This study was undertaken to investigate the perception and the consumption behavior for the meats in Koreans. The subjects were 491 Koreans including the ones residing in New Zealand. Most of subjects answered the meats are used for supper time. The frequency of the meats intake was affected by education and monthly income level. 69.2% of the subjects had positive response such as increased stamina and fulled stomach for psychological state after the meats intake. The use of meats recently revealed that 48% of the subjects have decreased its consumption. The main reasons diminished the use of meats were for the good health and economic state. Women were found to avoid the meats fat to a greater degree than men. The kinds of the meat used frequently were beef, pork and chicken. The younger tended to higher the frequency of the processed meats intake than the older. According to 3 level of BMI of the subjects, there were significant differences in the amount of the meat intake and perception for necessity of the meat. This study showed that the higher the preference for meat, the education and the monthly income level, the more the meat intake frequency. There were not significant differences between Koreans residing in domestic and New Zealand except the dog meat in the perception and consumption of the meat.

This study was designed to provide fundamental data on the consumption of fast food for a balanced diet of university students. The effects of personal characteristics and preferences such as gender, major, residing region, living expense, school grade, dieting, physical activity, smoking and alcohol consumption on fast food consumption patterns were analyzed by surveying university students. The analysis showed significant differences (p<0.05) in the consumption of different types of fast food depending on different personal characteristics and preferences as follows : hamburger by major, physical activity and alcohol consumption; chicken by school grade, physical activity and alcohol consumption; spaghetti by gender and smoking. Groups of different majors and school grades showed significant differences (p<0.05) in response to a question "Have you ever eaten fast food for regular meals?". The choice of fast food types based on taste and price appeared to be significantly influenced by majors and gender. Different groups with different majors and dieting experience appeared to think significantly differently about fast food. In response to a question "Has the consumption of fast food changed your diet style" different groups of different majors and physical activities showed significant differences. The analysis of factors affecting fast food choices revealed that fast food is chosen significantly differently depending on gender and majors (p<0.05). The purchase of fast food appeared to be significantly affected by gender, diet, physical activity, experience of fast food and consumption of fast food for regular meals (p<0.05).

Polycyclic aromatic hydrocarbons (PAHs) are dangerous chemical compounds that can be formed by cooking foods at high temperatures. The aim of this study is to determine the level of contamination of PAH compounds with high performance liquid chromatography (HPLC) on heat treated meat samples and the consumption of PAH compounds in meat samples, as well as the dietary exposure status and possible health risk estimation. In five different heat treated meat samples (meat doner, chicken doner, meatballs, grilled chicken, and fish), the total PAH (Σ16PAH) contamination level was 6.08, 4.42, 4.45, 4.91, and 7.26 ㎍/kg, respectively. Benzo[a]pyrene (BaP) in meatballs and grilled fish samples had a level 0.70 and 0.73 ㎍/kg. All of the samples analyzed were found to be below the EU permitted limit (5 ㎍/kg) in terms of BaP. Estimates of daily intake (EDI) for a total of 16PAH in heat treated meat doner, chicken doner, meatballs, grilled chicken and fish samples were 3.41, 3.71, 2.49, 4.12, and 1.77 ng/kg bw/day, respectively. In this study, the average margin of exposure (MOE) value calculated was found in the range of 179.487 and 425.000 for BaP and PAH4. This study is the first study to provide important information in terms of evaluating the possible health risk that PAH compounds can create in people's diets due to heat treatment of meat and meat products in Sivas, Turkey.

Food safety is the most important global health issue due to foodborne pathogens after consumption of contaminated food. Foodborne bacteria such as Escherichia coli, Salmonella enterica, Staphylococcus aureus, Campylobacter spp., Bacillus cereus, Vibrio spp., Yersinia enterocolitica and Clostridium perfringens are leading causes of the majority of foodborne illnesses and deaths. These foodborne pathogens often come from the livestock feces, thus, we analyzed fecal microbial communities of three different livestock species to investigate the prevalence of foodborne pathogens in livestock feces using metagenomics analysis. Our data showed that alpha diversities of microbial communities were different according to livestock species. The microbial diversity of cattle feces was higher than that of chicken or pig feces. Moreover, microbial communities were significantly different among these three livestock species (cattle, chicken, and pig). At the genus level, Staphylococcus and Clostridium were found in all livestock feces, with chicken feces having higher relative abundances of Staphylococcus and Clostridium than cattle and pig feces. Genera Bacillus, Campylobacter, and Vibrio were detected in cattle feces. Chicken samples contained Bacillus, Listeria, and Salmonella with low relative abundance. Other genera such as Corynebacterium, Streptococcus, Neisseria, Helicobacter, Enterobacter, Klebsiella, and Pseudomonas known to be opportunistic pathogens were also detected in cattle, chicken, and pig feces. Results of this study might be useful for controlling the spread of foodborne pathogens in farm environments known to provide natural sources of these microorganisms.

Since its introduction in"Jeungbosallimgyeongje" in the mid-1700s, Chogyetang has continuously changed as a cooked food while still reflecting the era as in the following four phases. In the first phase from 1766 to 1920, Chogyetang was served as a hot pot dish consisting of boiled chicken with spring onions, vinegar, soy sauce, oil, and egg. The second phase from 1930 to 1950 involved the removal of vinegar, an important seasoning. Instead, a wider variety of materials such as beef, sea cucumber, abalone, cucumber, and mushroom were added. Third, from the late-1950s to 1980s, there were significant changes both in the materials and recipe. Chogyetang was changed into a cold food for consumption in the summer in which sesame, a new material, was added to make soup. The prepared soup was then poured over the chicken and vegetables. Fourth, from the late-1980s to the present, sesame, the main ingredient added in the third phase, was removed. Instead, vinegar, mustard, and sugar were added in order to increase taste. Therefore, Chogyetang has been changed into an a la carte menu item in which vegetables and noodles are added to boiled chicken, and it has become a popular summer food consumed when eating-out.

The chicken egg provides a perfectly packaged, portion controlled, highly nutritious food containing vital nutrients essential for maintaining human health. However, concern by health professionals over the possible association of diets high in fat and cholesterol to chronic diseases has led to a decrease in egg consumption. Several different strategies have been adopted by the poultry food industry to enhance the nutritional value of eggs. The major emphasis has been focused on the modification of polyunsaturated fatty acid composition and fat soluble vitamins. This review briefly describes the composition, lipid nutrient content and the positive health effects of egg lipid nutrients.

This study was conducted to compare growth performance, carcass characteristics and meat quality of 4 breeds of local chicken. A total of 480 1-d-old chicks were distributed to 16 pens, with 4 treatments of breed, 4 replicates and 30 chicks per pen. Three Korean local breeds of white-mini broiler, Hanhyup-3-ho, and Woorimatdag, and a breed of silky fowl were raised under identical rearing and feeding conditions for 31-d, 37-d, 36-d, and 59-d, respectively. The BW and feed consumption on a pen basis were weekly measured for all pens, and ADFI, ADG and gain:feed were calculated for each pen. The ADFI and ADG of 3 breeds of Korean local chicken were greater than those of silky fowl (p<0.05). Within the Korean local breeds, ADFI of white-mini broiler was the highest (p<0.05), and ADG of Hanhyup-3-ho and white-mini broiler was the highest (p<0.05). Gain:feed of silky fowl was less than that of the 3 breeds of Korean local chicken. The carcass and breast yield of white-mini broiler were the greater than those of other breeds (p<0.05). The breast meat color (CIE $L^*$, $a^*$, and $b^*$) of 3 breeds of Korean local chicken were higher than that of silky fowl (p<0.05). The breast meat of Hanhyup-3-ho had greater cooking loss (p<0.05), whereas water holding capacity and pH were less than those of other breeds (p<0.05). The color score of 3 breeds of Korean local chicken was higher than that of silky fowl (p<0.05). Woorimatdag had a higher score on tenderness (p<0.05), whereas flavor score was less than that of other breeds (p<0.05). In conclusion, 4 local breeds of chicken have some unique features and seem to have more advantages, and this information can help consumers who prefer healthy and premium chicken meat.

While there are persistent rumors that the consumption of goat meat dishes increases blood pressure, there is no scientific evidence to support this. Two experiments were conducted to clarify whether or not blood pressure increases in conjunction with the consumption of goat meat dishes. In experiment 1, 24 Dahl/Iwai rats (15 weeks old, body weight $309.3{\pm}11.1$ g) were evenly separated into 4 groups. The control group (CP) was fed a diet containing 20% chicken and 0.3% salt on a dry matter basis. The goat meat group (GM) was fed a diet containing 20% goat meat and 0.3% salt. The goat meat/salt group (GS) was fed a diet containing 20% goat meant and 3% to 4% salt. The Okinawan mugwort (Artemisia Princeps Pampan)/salt group (GY) was fed a diet containing 20% goat meat, 3% to 4% salt and 5% of freeze-dried mugwort powder. The experiment 1 ran for a period of 14 weeks during which time the blood pressure of the animals was recorded. The GS, and GY groups consumed significantly more water (p<0.01) than the CP and GM groups despite the fact that their diet consumption levels were similar. The body weight of animals in the CP, GM, and GS groups was similar while the animals in the GY group were significantly smaller (p<0.01). The blood pressure in the GM group was virtually the same as the CP group throughout the course of the experiment. In contrast, while the blood pressure of the animals in the GS and GY group from 15 to 19 weeks old was the same as the CP group, their blood pressures were significantly higher (p<0.01) after 20 weeks of age. The GY group tended to have lower blood pressure than the GS group. In experiment 2, in order to clarify whether or not the increase in blood pressure in the GS group and the GY group in experiment 1 was caused by an excessive intake of salt, the effects on blood pressure of a reduction of salt in diet were investigated. When amount of salt in the diet of the GS and GY group was reduced from 4% to 0.3%, the animal's blood pressure returned to normotensive. These results indicate that, as in the case of chicken consumption, prolonged consumption of goat meat does not cause increased blood pressure, rather the large amount of salt used in the preparation of goat meat dishes is responsible for the increase in blood pressure.
