A study has been performed on the cockroach knowledge and perception of managers, employees and consumers, and the cockroach control management in food service institutions. A total of 759 subjects including 101 managers, 293 employees and 365 consumers was surveyed in Seoul and Pusan areas from July 1994 to September 1994. The results obtained are as follows: The mean rates of the cockroach knowledge (i.e. 62.26/100.0) and perception (i.e. 23.67/30.0) of the consumers were significantly (p<0.001) lower than those of the managers (i.e. 68.87/100.0 and 25.30/30.0, respectively) and the employees (i.e. 69.09/100.0 and 26.99/30.0, respectively). In the cockroach detection rates, however, much higher rate was seen in the consumer group (i.e. 79.5%) than the manager (i.e. 43.3%) and the employee (i.e. 48.5%) groups. Forty and seventy percents of the subjects have suffered from allergies and nuisance by cockroaches, respectively. The cockroach control was performed by 75.5% of the food service institutions and 70.8% of them contracted with pest control operators to reduce the cockroach populations. The cockroach control methods of the operators were aerosol (40.7%) and insecticidal baits (30.5%). Only 33.7% of the institutions had the budgets for the cockroach control. For public health, the managers and the employees of the institutions need to be educated about cockroaches and hygiene. Also, it is suggested that cockroaches be regularly controlled by professional pest control operators.
