Abstract

The sources of microbiological contamination in shellfish harvesting areas in the Ashtamudi and Vembanad estuaries were identified through a sanitary survey. Samples of shellfish and waters were tested for faecal indicator bacteria. Both estuaries receive high levels of contamination from septic tank discharges and areas with high numbers of birds and livestock. An assessment to illustrate the classification status of the harvesting areas indicated that 64% of oyster and 58% of clam samples from Ashtamudi and 54% of mussel samples from Vembanad would comply with the lower class B standard of the EU classification system. Most water results would comply with the faecal coliform standard for ‘Prohibited’ areas under the US classification system. None of the water samples from Ashtamudi were below the standard for ‘Approved’ areas. Pollution reduction measures and implementation of a sanitation programme according to international best practice would improve consumer health protection.
