Hydatid worms, hosted by humans and animals, impose serious human health risk and cause significant livestock production loss. To better understand the disease infection status in Xinjiang, China, we investigated the disease epidemics in 4 livestock animals, i.e., cattle, sheep (both sheep and goat), camels, and horses, slaughtered at the abattoirs in Urumqi, Yining, Tacheng, and Altay areas. The results showed that the animals were infected at different rates, in the order of sheep (9.8%), cattle (8.4%), camels (6.8%), and horses (4.3%). The infection rates were found to be different between the abattoirs in various regions even for the same animals. For sheep, the rates increased significantly as the animals grew older. It was 1.9% before 1 year of age and increased to 8.2% in the age of 1-2 years, and further increased to 12.3% when the animals were 3-4 years old, and reached 17.2% when they were 5-6 year old. Sheep older than 6 years had an infection rate of 19.5%. This study demonstrates that the 4 livestock animals in the pastoral areas in Xinjiang were infected by the parasites to various extend. This study is the first systematic investigation of the hydatid worms in various livestock animals in Xinjiang, China, which provides epidemiological information about the infection of hydatid worms in livestock, and is valuable in developing strategies for prevention and control of the hydatid disease.

The purpose of this study was to investigate basic data on the degree of parents' recognition and satisfaction with the use of environment-friendly agricultural products. The conclusions of this study are as follows. The survey on the use of environment-friendly products in households showed that 68.7% of the respondents used environment-friendly products at home. The frequency of purchasing organic products by household consumers showed that 25.1% of the respondents bought organic products one to two times per week. The most popular items of the environment-friendly agricultural products used were vegetables, comprising 63.9%. The households with more than 3,000,000 won of monthly income tended to consume more domestic livestock products (p < 0.05). In comparison to general agricultural products, environment-friendly agricultural products users showed higher satisfaction level with a better quality in term of safety, quality, nutrition, taste, appearance, diversity and price. The degree of satisfaction with safety was the highest (3.8 +/- 0.68), and price showed the lowest (2.76 +/- 0.79). The degree of parents' recognition of the governmental support for environment-friendly agricultural products showed that those who were aware of the supporting policy were 44.5%, but 55.5% of them didn't know about the fact that 46.6% of the respondents agreed that environment-friendly agricultural products should be used in more than 50% of the foods used for school food service. The respondents pointed out that vegetables (45%) sprayed with pesticide are the most urgent food item that need to be replaced by environment-friendly farm products.

The analytical method of trace toxic metals in livestock products was confirmed and validated through certified reference material (CRM) and the international proficiency tests. There are some difficulties to determine low levels of toxic metals in livestock products because of interferences due to the matrix. The recoveries of CRM (NIST 1577c) ranged from 73.9 to 119% for lead and from 86.4 to 111% for cadmium in bovine liver. The international proficiency tests were carried out with the milk powder and cocoa powder samples including metals provided by Food Analysis Performance Assessment Scheme (FAPAS(R), UK). The test samples were prepared by microwave digestion using solution of HNO3 : H2O2 : H2O (v/v/v = 5 : 2 : 4) and analyzed by ICP/MS. The analytical result of cadmium in milk powder was 121 microg/kg with -0.3 of the z-score compared to the assigned value of 131 microg/kg by FAPAS(R). The analytical results of lead and cadmium in cocoa powder were 29.2 microg/kg and 97.6 microg/kg, respectively, which satisfied the assigned values of 34.2 microg/kg for lead and 126 microg/kg for cadmium by FAPAS(R). It is verified that the analytical method is accurate and reliable to determine trace lead and cadmium in livestock products by microwave digestion and ICP/MS.

4.Genotyping of Coxiella burnetii strains detected in cattle from a nationwide survey in Korea
Journal of Veterinary Science 2019;20(1):95-97
A total of 123 Coxiella burnetii strains detected in cattle from a nationwide survey in Korea were classified into five genomic groups: I (0.8%), II (14.6%), III (12.2%), IV (66.7%), and V (5.7%). Acute Q-fever strains (Groups I, II, and III) comprised 27.6% and chronic strains (Groups IV and V) comprised 72.4%. At a dairy farm where both types were present, the detection rate was 6.7-times higher than that of another farm where only chronic strains were detected. Both acute and chronic Q-fever strains are widespread in Korea, and their presence could represent an active transmission to livestock and humans.

5.Future Management Strategies for Zoonoses Based on One Health
Journal of Agricultural Medicine & Community Health 2019;44(1):39-42
Zoonoses are the diseases that are transmitted to human being from vertebrate animals either from livestock animals or from wildlife. Recently, zoonoses are increasingly common as a result of incremental human-animal contact. Propagative infections in wild animals and livestock are transmitted to human beings who are encountered with them. In general, wild animals can transmit infectious agents to livestock, and then livestock further transmit them to human being is a simple model of on how zoonotic diseases get transmitted to human being. This model emphasizes the importance of early detection of zoonoses by surveillance at its incipient stage. Cooperation between the respective ministries plays an important role in the identification of zoonoses and planning for the formulation of better preventive and control policy and strategy. We will be able to predict the occurrence of zoonotic diseases in human on the basis of disease trends in wildlife and livestock once when we obtain the surveillance data and data generated by respective ministries through sound cooperation and collaboration.

Chinese medicine-probiotics compound microecological preparation for livestock and poultry is a new type of animal microecological preparations that combine probiotics with traditional Chinese medicine by modern fermentation technology. It could exert synergistic effects of both probiotics and traditional Chinese medicine, with the purpose of improving immune function of livestock and poultry and protect their health. By investigating the literature on probiotics and Chinese medicine microecological preparations in recent years, we summarized the background and strain characteristics of Chinese medicine-probiotics compound microecological preparations (CPCMP) for livestock and poultry in this paper. Furthermore, we elaborated the mechanisms of CPCMP for livestock and poultry and introduced the application of CPCMP in livestock and poultry breeding. Finally, we pointed out the existing problems and proposed the suggestions on the development of CPCMP. This review is expected to provide reference and basis for further research on CPCMP for livestock and poultry.

Twenty isolates of Bacillus species obtained from livestock manure composts and cotton-waste composts were tested for their antagonistic effects in vitro against three green mold pathogens of mushrooms (Trichoderma harzianum, T. koningii, and T. viridescens). However, there exists a possibility Bacillus species may have antagonistic effects against mushrooms themselves, and thus the same 20 isolates were tested in vitro against three species of mushrooms (Flammulina velutipes, Lentinus edodes, and Pleurotus ostreatus). Of the 20 Bacillus species isolates tested, two inhibited mycelial growth of T. harzianum, seven that of T. koningii, and eight that of T. viridescens. Importantly, the bacterial isolates M27 and RM29 strongly inhibited mycelial growth of all the Trichoderma spp. isolates tested. The isolate M27 was subsequently identified as the most effective in inhibiting mycelial growth of all the Trichoderma species. Interesting results of the effect Bacillus isolates had upon the mushroom species followed. It was found that most Bacillus isolates except 5T33 at least somewhat inhibited mycelial growth of the three mushroom species or some of the mushrooms. Furhermore, the antagonistic effects of the bacterial isolates against the three species of mushrooms varied depending on the mushroom species, suggesting a role for mushroom type in the mechanism of inhibition. The bacterial isolates M27 and RM29 were identified as having the most antagonistic activity, inhibiting mycelial growth of all the Trichoderma spp. as well as mycelial growth of the three species of mushrooms. These results suggest that the bacterial isolates and their antagonistic effects on green mold pathogens should be further studied for their practical use for biological control of green mold in the growing room of the mushrooms.

8.Study on Awareness and Consumption Behavior of the General Public and Livestock Farmers regarding Chikhanwoo.
Journal of the Korean Dietetic Association 2016;22(4):251-260
This study was conducted to determine recognition of Chikhanwoo, promote its market competitiveness, and vitalize its uses in Korea. This research was carried out on 465 people, including 264 of the general public and 191 livestock farmers. For awareness of Chikhanwoo, 53.6% of the general public and 86.9% of livestock farmers recognized Chikhanwoo (P<0.001) through TV, Internet, news, magazines, and others. For consumption behaviors of Chikhanwoo meat, 4.3% of the general public and 1.9% of livestock farmers have purchased Chikhanwoo meat in the past. Most of them hinted at their intention to repurchase and highly intimated their wish to purchase on whether Chikhanwoo tastes better, is more nutritious and is safer than Hanwoo. In addition, they thought country of origin and price were the most important factors for purchasing (P<0.001). For recognition of the Hanwoo grading system, they preferred 1⁺⁺ and 1⁺, significantly (P<0.001). For need for quality certification, most respondents thought that the government should introduce a quality certification system for Chikhanwoo. For importance factor of prevalence of Chikhanwoo meat, marketability value had the highest degree of importance, followed by taste, quality, tradition and cooking methods (P<0.001). Results of this study show that domestic consumption of Chikhanwoo can be boosted by supplying Chikhanwoo meat with a differentiated taste and a safety assurance to the general public. There is also need to enhance genetic resources and improve brand value of Chikhanwoo. Continuous research and efforts should be made for the development of the livestock market.

Safety and Health at Work 2010;1(2):183-191
OBJECTIVES: The objective of this study is to investigate the distribution patterns and exposure concentrations of bioaerosols in industries suspected to have high levels of bioaerosol exposure. METHODS: We selected 11 plants including 3 livestock feed plants (LF industry), 3 metal working fluids handling plants (MWFs industry), and 5 sawmills and measured total airborne bacteria, fungi, endotoxins, as well as dust. Airborne bacteria and fungi were measured with one stage impactor, six stage cascade impactor, and gelatin filters. Endotoxins were measured with polycarbonate filters. RESULTS: The geometric means (GM) of the airborne concentrations of bacteria, fungi, and endotoxins were 1,864, 2,252 CFU/m3, and 31.5 EU/m3, respectively at the sawmills, followed by the LF industry (535, 585 CFU/m3, and 22.0 EU/m3) and MWFs industry (258, 331 CFU/m3, and 8.7 EU/m3). These concentrations by industry type were significantly statistically different (p < 0.01). The ratio of indoor to outdoor concentration was 6.2, 1.9, 3.2, and 3.2 for bacteria, fungi, endotoxins, and dust in the LF industry, 5.0, 0.9, 2.3, and 12.5 in the MWFs industry, and 3.7, 4.1, 3.3, and 9.7 in sawmills. The respiratory fractions of bioaerosols were differentiated by bioaerosol types and industry types: the respiratory fraction of bacteria in the LF industry, MWF industry, and sawmills was 59.4%, 72.0%, and 57.7%, respectively, and that of fungi was 77.3%, 89.5%, and 83.7% in the same order. CONCLUSION: We found that bioaerosol concentration was the highest in sawmills, followed by LF industry facilities and MWFs industry facilities. The indoor/outdoor ratio of microorganisms was larger than 1 and respiratory fraction of microorganisms was more than 50% of the total microorganism concentrations which might penetrate respiratory tract easily. All these findings suggest that bioaerosol in the surveyed industries should be controlled to prevent worker respiratory diseases.

Brucellosis is a zoonosis caused by Brucella species. B. melitensis, B. suis, B. abortus and B. canis can infect humans. Recently, as the cases of bovine brucellosis have increased every year in Korea, the cases of human brucellosis have also increased among livestock workers and veterinarians in rural areas, since the first human case was reported in 2003. Because clinical manifestations of the disease are nonspecific and may be very atypical, clinicians and laboratory persons need to be active in using diagnostic tools including polymerase chain reaction in addition to the ordinary culture and serologic tests, and taking an appropriate measure to prevent intralaboratory infection. We report herein our experience in three human brucellosis cases diagnosed by cultures, serologic tests and gene detection.
