Description Live clams (Villorita cyprjnoides) from Vembanad Lake (Kerala) and live mussels (Perna viridis)
from Calicut (Kerala) were examined for their bacteria and sand content. It was observed that the
flesh of these bivalves harboured large bacterial populations Including faecal coliforms, Escherichia coli
and faecal streptococci. Also their intestines contained mud and sand (acid insoluble ash) sufficient to
impart muddy flavour and grit~ness to the meat. A cleansing operation to achieve the elimination of
pathogenic/indicator bacteria, mud and sand from the clam and mussel meat has been worked out.
process involves depuration of the bivalves in their clean natural water for 18-24 h, followed by chlorination
of the system to 6 ppm level and maintaining in that condition for an additional 2 h. By this
process, there was complete remove1 of pathogenic indicator bacteria from their muscle. Also, the acid
insoluble ash decrease to negligible levels.
