Up to now no specific legislation on water’s microbiological characteristics in basins used for aquaculture is available; therefore, it is very important to monitor their hygienic and sanitary quality. Fish inhabiting faecally polluted bodies of water are often used for human consumption. Such fish can be contaminated by enteric human pathogens and may pose a potential risk to public health. Aim of the present study was to estimate the level of hygiene and sanitation on the brackish water basin of Acquatina used for extensive and semi-intensive fish-culture. Six sampling points were set up and the following microbiological parameters were measured: total and faecal coliforms, faecal streptococci and Salmonella spp. The highest level of total coliforms and faecal coliforms were observed in the channels (Cardone 636 TC 100 mL−1, 305 FC 100 mL−1 and Giammatteo 267 TC 100 mL−1 229 FC 100 mL−1) while the concentration of contaminants of faecal origin in the basin was quite low during the whole year studied. Therefore, these results suggest that freshwater introduced by the channels could be a potential source of faecal contamination.

Abstract
Up to now no specific legislation on water’s microbiological characteristics in basins used for aquaculture is available; therefore, it is very important to monitor their hygienic and sanitary quality. Fish inhabiting faecally polluted bodies of water are often used for human consumption. Such fish can be contaminated by enteric human pathogens and may pose a potential risk to public health. Aim of the present study was to estimate the level of hygiene and sanitation on the brackish water basin of Acquatina used for extensive and semi-intensive fish-culture. Six sampling points were set up and the following microbiological parameters were measured: total and faecal coliforms, faecal streptococci and Salmonella spp. The highest level of total coliforms and faecal coliforms were observed in the channels (Cardone 636 TC 100 mL−1, 305 FC 100 mL−1 and Giammatteo 267 TC 100 mL−1 229 FC 100 mL−1) while the concentration of contaminants of faecal origin in the basin was quite low during the whole year studied. Therefore, these results suggest that freshwater introduced by the channels could be a potential source of faecal contamination.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
