For the safety assessment of microbiological and chemical hazards in raw short-neck clam Ruditapes philippinarum
distributed in the Yeongnam and Honam areas during the spring season, the contamination levels of total viable
bacteria, coliforms, Escherichia coli, and nine pathogenic bacteria (Staphylococcus aureus, Salmonella spp., Vibrio
parahaemolyticus, Clostridium perfringens, Listeria monocytogenes, enterohemorrhagic Escherichia coli, Yersinia
enterocolitica, Bacillus cereus, Campylobacter jejuni ) as microbiological hazards, and heavy metals (lead, cadmium,
total mercury), benzopyrene, shellfish poison (paralytic, diarrhetic, amnesic), and radioactivity (131I, 134Cs+137Cs)
were also analyzed in 15 samples based on the methods of the Korean Food Code. The average contamination levels
of total viable bacteria were 3.11 (1.40-4.49) log CFU/g, and coliforms were detected in 5 out of 15 samples (1.18-
1.85 log CFU/g). E. coli and S. aureus were not detected in all samples. Furthermore, the presence of 8 pathogens
were not detected in all samples. The average contamination levels of lead, cadmium, and total mercury were 0.155
(0.079-0.264), 0.160 (0.040-0.287), and 0.017 (0.008-0.026) mg/kg, respectively. Benzo(a)pyrene, shellfish poison,
and radioactivity were not detected in all samples. The results of this study suggest that the safety against all microbiological
and chemical hazard factors in raw short-neck clams distributed in markets has been assured.
