Because of recent global and domestic issues regarding the safety of food, there is growing concern over food safety and interest in the country-of-origin for food ingredients from restaurants. This study was conducted to reveal the influence of consumer level of knowledge and awareness regarding restaurants and the country-of-origin labeling.


To accomplish this, a primary survey of adults aged over 20 years old was conducted to measure customers' knowledge regarding country-of-origin labeling for restaurants. Respondents were then divided into a lower group and an upper group based on their level of knowledge to evaluate significant differences between groups. A total of 437 of 460 questionnaires were analyzed.


The average knowledge score regarding country-of-origin labeling for restaurants was 6.3 out of 10. Additionally, there were significant differences between the lower and upper group in terms of the final education level and occupation.


It is necessary to develop guidelines and public relations for country-of-origin labeling of restaurants.
