This survey was conducted to evaluate the microbiological quality and to detect of pathogenic microorganisms on the surface of slaughtered beef and pork products in two abattoirs located in Seoul from January 2001 through December 2001. Two hundred and twenty-five beef and 215 hog were surveyed for microbiological quality and 630 beef and 625 hog were detected for pathogenic microorgainsms. 1. The prevalence level on number of standard plate count(SPC) less than 10(4)cfu/cm(2) in beef and hog were 89.8% and 90.7%, respectively. 2. Escherichia coli less than l0(2)cfu/cm(2) in beef and less than l0(3)cfu/Cm(2) in hog were 98.2% and 99% 3. E coli O157:H7 was recovered from 2 beef carcasses(0.32%), and Staphylococcus aureus from 12 pork carcasses(1.90%), Listeria monocytogenes from 1 beef and 4 pork carcasses (0.15%, 0.64%) and Clostridium perfringens from 14 beef and 11 pork carcasses(2.22%, 1.76%), respectively.

This study was conducted to investigate the prevalence rate for rabies antibody (PRRA) of dogs near the Pukhansan National Park and in some other districts in Seoul Metropolitan city. From April to July 2000, a total of 414 serum samples were taken from dogs for breeding (92), pet dogs (62), and unclaimed/stray dogs (62). Rabies virus antibodies were detected by neutralizing peroxidase-linked assay (NPLA). Of 414 sera tested, 145 (35%) were positive to rabies virus antibody. PRRA in Pukhansan National Park area and in the other districts of Seoul city were 34.8% and 35.4%, respectively. There was no significant difference in the prevalence rate between these two districts. PRRA in pet dogs, unclaimed/stray dogs, and dogs for breeding were 39.5%, 35%, and 27.2% respectively. PRRA in dogs from residential areas, apartments, animal hospitals, and farms were 32.5%, 60%, 35.3%, and 26.7% respectively. Especially, the dogs reared in apartments had a significantly higher seroprevalence (60%) than those in residential or farm areas. PRRA in less than 1 year, 1~<2 years, 2~<3 years, and over 3 years old dogs were 14.7%, 40.4%, 38.4%, and 53% respectively, and overall 35% in the dog population. In addition, we found that dogs less than 1 year of age had lower antibody prevalence than those over 1 year of age. It was concluded that enhancement of vaccination is important in the prevention of the rabies, and that rabies vaccines should not be less supplied than the population of the dog.

To demonstrate the prevalence of Toxocara spp. eggs in public playgrounds in Seoul city, sand samples collected from March to October in 2000 were examined. Of 1,812 sand samples from 302 playgrounds surveyed, Toxocara canis eggs were detected in 38 sands from 22 place(7.3%). Sand samples in public parks were more contaminated (10%) with the eggs than those in apartment complex area(7.1%) and in residential area(6.8%). Toxocara canis eggs were mostly found in sands in the spring and autumn but were not found in summer. To prevent the comtamination of Toxocara spp. eggs in the public places, the control of dogs and cats wandered do out there will be needed.
