This study was conducted to determine the total coliform (TC), and fecal coliform (FC) counts and bacterial loads of the skin, gills, intestines, and muscles of grouper, ariolated grouper (Epinephelus areolatus), orange-spotted grouper (Epinephelus coioides), coral trout (Plectropomus areolatus), roving coral grouper (Plectropomus pessuliferus), and moontail seabass (Variola louti). The aerobic bacterial counts of the groupers' skin, gill, intestine, and muscle samples ranged from 9.04 ± 0.14 to 11.57 ± 0.82, 7.69 ± 0.89 to 11.51 ± 0.51, 7.49 ± 0.14 to 11.54 ± 0.41, and 4.41 ± 0.49 to 4.64 ± 0.35 log CFU/g, respectively. The total coliform counts were presented in skin with the values of 1100 MPN/g, while in gills and in intestines the values ranged from 460 to 1100 MPN/g and 240 to 460MPN/g, respectively. The fecal coliform counts were found in skin and gill samples, with the values ranged from 150 to 240 MPN/g and 64 to 150 MPN/g, respectively. In contrast, the total coliform and fecal coliform counts were not detected in all the groupers' muscle samples.
