Abstract
Semi-dried non-irradiated anchovies (Anchoviella commersoni), initially exhibited the
presence of Micrococcus (15%), Bacillus (60%) and Staphylococcus (20%) microflora. On the
other hand, Bombay duck (Harpodon nehereus) and Vietnam scads (Alepes mate) were found
to be contaminated predominantly by Bacillus and Staphylococcus sp. respectively.
Irradiation (3 kGy) of semi-dried anchovies resulted in modification of microbial
composition which comprised of Bacillus (50%) and Staphylococcus (50%), while microflora
of semi-dried irradiated Bombay duck consisted of Bacillus sp. only. These results suggested
that irradiation of semi-dried fish resulted in the elimination of Micrococcus leaving the
survivors belonging to Bacillus sp. and Staphylococcus sp.
