Abstract
Bacteriological examination of the natural waters in which clams ( Egeria radiata ) grow in the Cross River in Akwa Ibom State, Nigeria, showed that the waters were generally of an unacceptable quality for growing market shellfish. Egeria radiata samples collected from the waters were also found to be highly contaminated by bacteria. Mean log total aerobic bacterial count, total coliform and faecal coliform most probably numbering densities as high as 6·64, 2·18 and 1·40 per 100 ml water, respectively, were found at the most contaminated growing area. A mean total aerobic bacteria of 8·1×10 7 per 100 g meat was found on clams from this area which also showed a bacterial concentration factor as high as 1:26. The bacterial counts between the three locations studied were, however, not statistically significant ( P >0·05) with respect to any of the tests conducted. Depuration was very effective in eliminating bacteria from the clams, with a 97% reduction observed within the first 24 h of depuration.
