“…parahaemolyticus was enumerated by spreadplating 0.1-ml samples of oyster homogenate onto thiosulfate-citrate-bile salts-sucrose agar (Oxoid). After incubation at 37°C for 24 h, typical blue-green colonies of V. parahaemolyticus were counted and confirmed by the following biochemical tests: indole, acetoin, oxidase, and lysine decarboxylase production; reaction on triple sugar iron agar (Oxoid); growth in the absence of salt; growth in the presence of 8 and 11% salt; and growth at 42°C (19,31).…”

Oysters (Crassostrea commercialis) harvested from major cultivation areas within the state of New South Wales, Australia, were commonly contaminated with low levels of the food-poisoning organisms Bacillus cereus, Clostridium perfringens, and Vibrio parahaemolyticus. Salmonella was found in oysters on only one occasion. These bacteria were cleansed from oysters during oyster purification by relaying in a non-polluted waterway. Oysters were laboratory contaminated to levels in excess of 1,000 cells per g with either B. cereus, C. perfringens, V. parahaemolyticus, Salmonella typhimurium, or S. senftenberg. These species were cleansed from such oysters during purification in a laboratory depuration unit that used ultraviolet light for sterilizing the depuration water. Escherichia coli was also cleansed from oysters under the same relaying or depuration conditions so that its measurement alone could be used to indicate the cleansing of the above pathogenic species. The levels of these bacteria were also measured during the storage of oysters under conditions that occur during marketing. While B. cereus counts remained relatively stable during storage, the Salmonella spp. gradually decreased in numbers and C. perfringens rapidly died off. V. parahaemolyticus counts increased slightly during the first 4 days of storage, after which decreases occurred.

“…coli, the indicator organism universally used, is generally not as resistant as most pathogenic Enterobacteriaceae and is much less resistant than the viruses, the presence of which they should indicate. In dehydrated foods (Brown & Gibbons, 1950), shellfish (Kelly & Arcisz, 1954), food stored in a frozen condition (Burton, 1949 Mossel, 1962) and, of course, the frequently employed Lancefield's group D streptococci are of much more value as indicator organisms. The situation may therefore be summarized as follows.…”

“…Most bacteriological studies on marine molluscs have been concerned with the public health problems often associated with eating shellfish, for example the incidence and survival of Salmonella and Shigella (Kelly & Arcisz, 1954 ;Colwell & Liston, 1961) . These workers also reported on the presence of Escherichia coli and other indicator organisms as did Thomas & Jones (1971) who concluded that the incidence of salmonellae in their unpurified mussels was related to the incidence of salmonellosis in the Conwy population.…”

The freshwater mussel Anodonta cygnea and four marine shellfish (mussels, Mytilus edulis; cockles, Cerastoderma edule ; clams, Mya arenaria ; Scrobicularia plana) from a total of six sites were surveyed for Escherichia coli, Clostridium perfringens, faecal streptococci, 25 and 37 ° C coliforms, 25 ° C and 37 ° C total viable numbers and fluorescent pseudomonads . The A . cygnea from an urban lake contained greater numbers of the faecal indicator bacteria than animals from a rural lake . There were also differences in the other bacterial counts and these were discussed with respect to bacterial parameter and animal characteristics . When freshwater mussels were transferred from the city site to the rural site for 24 h the load of faecal indicator bacteria was eliminated or significantly reduced . Other bacterial types took longer to become stabilised . Loss of indicator bacteria from Anodonta was also demonstrated using cleansing in the laboratory . Very high bacterial numbers were found in some marine molluscs notably Scrobicularia plana and most shellfish contained significant numbers of the three faecal indicator bacteria at every sampling occasion . The relationship between bacterial types was discussed and it was concluded that in both freshwater and marine animals the bacterial numbers were determined more by sampling site than by species of shellfish .
