The average prevalence rate (PR) for foodborne disease outbreaks (FBDOs) in the first half (F-H) and latter half(L-H) of the decade from 2001 to 2010 in Korea was 14.0 and 16.9 per 100,000 population, respectively. The number ofpatients per outbreak of foodborne diseases (FBDs) in the F-H of that decade was 57.6 and in the L-H was 25.4 (p < 0.05). A comparison of the 2 periods covered in this study indicates that FBDOs in the L-H most frequently involved restaurantsor delis (51.5% of total cases), and in the F-H, this involvement was noted in 34.0% of total cases (p < 0.01). The epidemicpatterns of microbial FBDOs show that the overall incidence of outbreaks resulting from 5 of 8 key pathogens includingBacillus cereus (+1.6%), Campylobacter jejuni (+1.5%), Clostridium spp. (+0.7%), pathogenic Escherichia coli (+8.3%), andNorovirus (+14.4%) tended to be higher in the L-H than in the F-H of the decade from 2001 to 2010. Conversely, thosecaused by the other 3 key agents, including Salmonella spp. ( 9.2%), Staphylococcus aureus ( 2.8%), and Vibrioparahaemolyticus ( 6.4%) were significantly lower in the L-H than in the F-H of the decade. Moreover, in the decade between2001 and 2010, the number of patients (n) and the PR for microbial FBD increased from the F-H (n = 13,346, PR: 5.6) tothe L-H (n = 33,732, PR: 13.8) (p < 0.01).
