Cultivate of shellfish products that enter the market must meet food safety standards. In order to support the achievement of this system, it is necessary to monitor and analyze the content of dangerous contaminants including heavy metals and biotoxins in shellfish products as well as heavy metal content in waters where shellfish are cultivated. The aim of this activity is to analyze the content of dangerous contaminants in marine waters and sediments for shellfish cultivation activities on the north coast of Java and to analyze the content of heavy metals and biotoxins in shellfish.This review of the shellfish sanitation program can identify locations for developing shellfish cultivation and Aquaculture in other marine and brackish sectors. so as to produce Aquaculture and shellfish products that are safe for consumption and obtain supporting data on which waters are suitable for sustainable Aquaculture programs.
The sampling points are based on shellfish cultivators located along the North Coast of Java with the highest production levels. The samples taken included sea water, sediment and several types of shellfish that could be consumed. Water samples taken at a certain surface and depth. Sediment is taken from the bottom of the waters where the shellfish live. the results of observations and analysis in the laboratory.
Sediment from station 6 had heavy metal Hg levels exceeding the maximum limit. Shellfish samples at stations 4 and 5 had biotoxin contents of 6.86 mg/kg and 3.52 mg/kg, respectively. This value is above the quality standard required in the Decree of the Minister of Maritime Affairs and Fisheries (KEP.17/MEN/2004). Areas whose biotoxin contamination values are above the threshold are included in class D based on existing regulations in Indonesia.
