Fish Tank Water Testing Services

Under section 10A of the Food Business Regulation (Cap 132 subsidiary legislation X), no person shall in the course of any food business keep any live fish or shell fish intended for human consumption in water of a quality below the standard specified by the Food and Environmental Hygiene Department (FEHD). The fish tank water standard is "E. coli less than 610 per 100 ml and absence of pathogenic organisms such as Vibrio cholerae".

Fish tank water from all licensed food premises and market stalls selling live seafood intended for human consumption will be collected by the staff of FEHD regularly to ensure the water quality complies with the requirements. If the E.coli content of water exceeds 180 cfu/100mL, the operators of the food premises will be alerted and they should take remedial measures to prevent deteriorating quality of fish tank water. In 

case if E.coli level exceeds 610 cfu/100mL, the owner of the food premises may be prosecuted and is liable to a maximum fine of $10,000 and imprisonment of three months upon conviction.
