Incidence of Salmonella in cultured shrimp Penaeus monodon

Shrimp are important aquaculture products in world fishery trade. Very little information is available on the microbiology of farmed shrimp. Levels of indicator organisms and the presence of Salmonella in the shrimp culture environment and in cultured shrimp were determined using standard methods. Salmonella was present in all the samples analysed. A poor correlation was observed between the level of indicator organisms and the presence of Salmonella, implying that Salmonella are a part of the natural flora of the shrimp culture environment and survive better than indicator organisms.
