Abstract:

Samples of oyster (Crassostrea lugubris) and cockle (Anadara granosa) meat and water and bottom sediments from their growing areas at Ban Don Bay, Surat Thani Province, were collected in March and August 1987. All samples were examined for total heterotrophic bacteria, total marine bacteria, total coliforms, fecal coliforms, Vibrio parahaemolyticus, V. alginolyticus, V. cholerae and Salmonella spp. The bacteriological quality of bivalves collected in March was acceptable while some of the samples in August contained indicator organisms above the recommended wholesale market standard. All the bacterial levels of the samples collected in August were higher than in March.
