HEALTH RISK ASSESSMENT AND MANAGEMENT FROM AQUATIC ANIMAL CONSUMPTION IN KWAN PHAYAO OF PEOPLE LIVING AROUND KWAN PHAYAO, PHAYAO PROVINCE

Abstract

The purposes of this research were to study food consumption pattern, food consumption behavior, and conduct health risk assessment and management from aquatic animal consumption in Kwan Phayao, Phayao Province, compared with the acceptable daily intake (ADI). Analysis of cadmium (Cd) and Lead (Pb) content in 6 aquatic animals (Macrobrachium lanchesteri, Filopaludina martensi, Clarias batrachus, Oreochromis niloticus, Monopterus albus and Channa micropeltes) indicated that cadmium was detected in Macrobrachium lanchesteri, Filopaludina martensi accounted to 0.0480 and 0.0200 mg/kg respectively. Moreover, lead concentrations (0.0325 mg/kg) were found in 3 aquatic animals including Macrobrachium lanchesteri, Filopaludina martensi and Clarias batrachus. Health risk assessment from Macrobrachium lanchester and Filopaludina martensi consumption with cadmium contamination showed a hazard quotient equaled to 0.27 and 0.11 respectively, and also the fact that average lead intake from aquatic animal was about 5.70 μg/day, lower than the TDI for about 36 fold (TDI of 3.60 μg/day body weight/day). In conclusion of this study, adverse health effects may not occur. Health risk management should be continued to monitor the contamination of cadmium and lead in aquatic animals and the environment consistently, as to act as a public health surveillance.
