Probabilistic Health Risk Assessment Due to Natural Formaldehyde Intake through Opah Fish (Lampris guttatus) Consumption in Indonesia

Opah fish(Lampris guttatus) is one of the bycatch products of Tuna fish captured originally from Indonesia that currently has become as one of the exported commodities. However, it is stated that these fish contains high formaldehyde up to 200 ppm, which is strongly suspected naturally due to deterioration. Furthermore, the aim of this study is to obtain the data of probabilistic health risk assessment due to consumption of opah fish that contaminated with natural formaldehyde. The study was conducted on opah fish (Lampris guttatus) that were analyzed the formaldehyde concentration in it. Along with the consumption data, body weight and the formaldehyde concentration included two others simulations of two times and four times of formaldehyde value, probabilistic dietary exposure was calculated by @Risk and produced some data regard to health risk. The result showed that Opah fish caught in Indonesian waters could produce formaldehyde naturally due to deterioration process ranged from 4,62 ± 0,00 mg/kg to 58,10 ± 0,46 mg/kg. Consequently, the residents of female children in Jakarta and Surabaya considered as in health risk problems. Extremely, the further simulations of two times and four times of formaldehyde concentration showed the health risk to all residents in Jakarta and Surabaya included male, female, children, and adult. Therefore, the stakeholders included government and policymakers should take some priorities to formulating a proper risk management strategy on the basis of knowledge of endogenous formaldehyde present in Opah fish and risk management strategies for the fish consumer in Indonesia.
