Shellfish quality standards.

Total coliforms, faecal coliforms, enterococci and heterotrophic bacteria were determined in shellfish samples collected both in the marine environment (at Bacoli and Coroglio in the Bay of Naples) and from the local market. The same bacteriological analyses were carried out on water samples obtained from the shellfish growing areas. The results are considered in relation to standards applied in Italy and elsewhere to shellfish and shellfish cultures.
