Norovirus (NV) is becoming a major cause of foodborne illness in many countries. At present, very little is known about the survival of NV in the environment or the disinfection procedures needed to remove NV from contaminated surfaces. Feline calicivirus (FCV, $1{\times}10^{6.75}\;TCID_{50}/mL$) was used as a surrogate model for NV to investigate the effectiveness of sanitizing treatments for the viruses attached to food and food contact surfaces. Ammonium chloride (2%), organic acids (3000 ppm), and ethanol (70%) were most effective, providing $4\;log_{10}$ (99.99%) reductions in FCV titers on food or food contact surfaces. The disinfection efficacies of most agents on ceramic and glass surfaces were greater than stainless steel. The results from this study can be applied in the food industry to reduce NV-associated foodborne illnesses.

Purpose: Previous studies have highlighted that the nutritional behaviors among South Korean workers are far from ideal. This study examined the organizational influences affecting the eating practices of office workers in South Korea. Methods: We conducted in-depth interviews with 22 office workers at 12 companies in South Korea. The interviewer inquired about the employees' daily routines on food and beverage intake. The various factors that influence their food choices in their work environments were also explored. The interviews were transcribed and then analyzed using a content analysis. Results: A framework analysis revealed 7 key recurring themes, and these were grouped under three levels: team-, company-, and corporate group-levels. First, team dinners are core social events for all the workers and they tend to include high-caloric food and alcoholic beverages. The frequency of team meals and the food associated with them depend on various team characteristics such as gender composition, the nature of a team's work and the team leaders' emphasis on group meals. Second, the company's policies and practices regarding budget allocation for team meals and subsidies for cafeteria meals affect the workers' food intake practices. In addition, the physical environment of the worksite cafeterias can influence the choices of foods. Third, various corporate group policies that were not designed to target food intake had additional positive effects on the workers' eating behaviors. Conclusion: This study provides important insights into the broader organizational influences on the food consumption of employees in their workplace. These insights can be used to design and implement more effective intervention strategies for improving the nutritional behaviors of office workers.

Objectives: This study examined the usage status and the degree of satisfaction of university foodservice (UF) perceived by international students in Busan. Methods: A questionnaire survey was conducted on the utilization of UF, improvement requirements, preference type and recipe, as well as the importance and satisfaction of UF quality attributes as perceived by international students (n=604) at universities in the Busan area between April and June 2017. Results: UF was 'generally satisfied' or 'very satisfied' in about 35.4% of the study population, and 'not very satisfied' or 'not satisfied at all' in approximately 11.5%. Approximately 21.7% said that UF contributed to dietary life 'very much' or 'quite significantly' and 36.4% said 'not very much' or 'not at all'. The largest demand for improvement of UF was 'variety of menu' (52.0%). The most leftover food in UF was kimchi (30.3%) and broth/stew (19.2%), and the major reason for having leftover was 'not to one's taste' (27.8%). After dividing the foodservice quality attributes into 5 factors - food quality and price, sanitation, convenience, physical environment, and service environment - and analyzing the importance and satisfaction of each factor, it was shown that satisfaction was generally lower than the degree of importance. Sanitation factor was high for both importance and satisfaction of UF, while convenience factor was high for the importance but low for satisfaction of UF. Four variables in the food quality and price factor ('food taste', 'freshness of food', 'nutritive value of food', and 'reasonable price') and 3 variables in the convenience factor ('variety of menu', 'prompt food service', and 'display of the meals for the day') had high importance but low satisfaction, showing the need for an improvement on these areas. Conclusions: Based on the study results, it is necessary to improve the food quality, as well as the price and convenience factors, and to provide various menus to increase the satisfaction of UF in international students.

Environment, food, and disease have a selective force on the present and future as well as our genome. Adaptation of livestock and the environmental nexus, including forest encroachment for anthropological needs, has been proven to cause emerging infectious diseases. Further, these demand changes in meat production and market systems. Meat is a reliable source of protein, with a majority of the world population consumes meat. To meet the increasing demands of meat production as well as address issues, such as current environmental pollution, animal welfare, and outbreaks, cellular agriculture has emerged as one of the next industrial revolutions. Lab grown meat or cell cultured meat is a promising way to pursue this; however, it still needs to resemble traditional meat and be assured safety for human consumption. Further, to mimic the palatability of traditional meat, the process of cultured meat production starts from skeletal muscle progenitor cells isolated from animals that proliferate and differentiate into skeletal muscle using cell culture techniques. Due to several lacunae in the current approaches, production of muscle replicas is not possible yet. Our review shows that constant research in this field will resolve the existing constraints and enable successful cultured meat production in the near future. Therefore, production of cultured meat is a better solution that looks after environmental issues, spread of outbreaks, antibiotic resistance through the zoonotic spread, food and economic crises.

Consumer anxiety about food safety is increasing, and the ability to make an accurate assessment is inadequate due to the lack of food safety information. This research focuses on relations among main variables, such as food hazard awareness, food apprehension, food safety information awareness, and food safety management system evaluation. In addition, to the moderating effects of food safety information awareness between food hazards awareness, food apprehension, and food safety management system evaluation. First, food hazards awareness and apprehension was slightly higher than the average level, also there was a significant difference in food hazard apprehension according to food hazard awareness. However, the level of food safety information was not high, meaning consumers were not as well informed as expected. We divided food safety management system evaluation into awareness and practice, subsequently, the results of both were at a low level. Food safety information awareness' moderating effect was also confirmed. Consumer organizations and the government need to provide specific and correct information to Korean consumers, that also implement a wide range of consumer education related policies.

Purpose: Along with the trend increasing dining-out and enjoying variety of menu, dessert café has been introduced as a new type of food service provider and grown up rapidly. We need to verify structural relationship that dessert café environment influences overall quality and brand image and loyalty. Research design, data, and methodology: This study seeks to understand how in-café environment influence overall quality, brand image and loyalty directly and indirectly based on SOR theory. We examine detail effect of in-café environment on overall quality and brand image and subsequently loyalty. Sample data were collected from 563 online survey panels and analyzed by using SmartPLS 3.2.9. Result: The results indicates that all sub-dimensions of in-café environment influences positively overall quality. While, menu and atmosphere make positive impact on brand image. price, food and beverage quality, employee service do not affect significantly brand image. Further, overall quality influences positively brand image and both overall quality and brand image affect positively loyalty. In addition, overall quality plays full mediator role in relationship among price, food and beverage quality, employee service and brand image. Conclusions: Dessert café should differentiate itself from competitors through physical and non-physical environments which are likely to influence overall quality. As overall quality mediates between environment and brand image and influences loyalty, dessert café is required to communicate strength of functional quality and service quality aggressively. Additionally, favorable brand image affecting loyalty is required to be dominated in advance as the market is likely to be segmented along with its growth.

The food service industry represents one of Korea's fastest-growing and most challenging areas of business but it is at the beginning of the industry. Italian cooking of the food service industry has a lot of merits but it is difficult to manage because of the shortage of domestic customers and the poor management of the industry. This research suggests the marketing strategies in order to systematize Italian food service satisfy the customers requirements and promote the sale of Italian food. The circulation structures should be simplified and systematized in order to enhance the quality of the food and lower the price. Italian food should be recognized as health food cooked with unsaturated fatty acid, olive oil. It is necessary that the Italian food for the Korea especially for the women and children be developed. The information about Italian food the advertisement of it should be structured because 13 percent of Italian food sale has dropped in the current environment.

BACKGROUND: The present investigation was aimed to predict the pre-harvest residue limits (PHRLs) of the fluopicolide and metrafenone on cherry tomato and to estimate their half-life and characteristics of the residues.METHODS AND RESULTS: Pesticides were treated once on cherry tomato in field 1 and 2 under the standard application rate. The samples were collected 7 times at the end of 0(2 hours after pesticides spaying), 1, 2, 3, 5, 7 and 10 days before harvest. Residues of fluopicolide and metrafenone were analyzed by the LC-MS/MS. In this study, the method limit of quantification (MLOQ) for both fluopicolide and metrafenone in cherry tomato was found to be 0.005 mg kg-1. Their recovery levels were 92.7∼94.8% and 82.6∼88.0%, shown with coefficient of variation of less than 10%. Half-life of fluopicolide and metrafenone in field 1 and 2 were found to be 15.0 days and 12.8 days, 18.9 days and 21.5 days, respectively.CONCLUSION: Based on the results, this study shows the level of PHRL on cherry tomato is 0.27 mg/kg for fluopicolide and 2.29 mg/kg for metrafenone at 10 days before harvesting. The present study indicates the residues of both pesticides on cherry tomato will be below maximum residue limit (MRL) at harvest.
