Background: Industrial waste generally contains a lot of heavy metals such as Plumbum (Pb), Arsenic (As), Cadmium (Cd) and Mercury (Hg), which can contaminate the surrounding environment and cause health problems. Bioaccumulation of heavy metals from the environment can occur in foodstuffs. The study aims to determine levels of heavy metals Pb, Cd, As and Hg in foodstuffs in the oil refinery industry. Methods: The analytical method used Atomic Absorption Spectrophotometer (AAS). Samples were taken from two locations, namely: the exposed area and non exposed area. The sample consisted of cassava, papaya leaves, fern leaves, cassava leaves, guava, papaya and catfish. Results: The analysis showed levels of metals As in all samples at exposed locations is below the maximum limit of SNI, the location is not exposed only in catfish levels of As (2.042 mg/kg) exceeds the SNI. Cd levels of both locations are not detected. Pb levels in catfish in exposed locations (1,109 mg/kg) exceeds the SNI. Hg levels in leaves of papaya, cassava leaves, fern leaves, cassava and fruit papaya exceed SNI. Conclusion: There has been a heavy metal contamination in foodstuffs. Recommendation: The local people are advised to be careful when consuming food stuffs from oil refinery industrial area.
