Heavy metals in offal and canned food sold in the Malaysian market.

Food contaminated with heavy metals poses a serious threat to consumers. This study aims to assess levels of lead (Pb) and cadmium (Cd) in offals of chicken, cattle, and pig as well as tin (Sn) in canned food. A total of 378 offal samples was collected from wet markets, while 218 canned food samples were purchased locally.

Association between dietary 3-monochloropropane-1,2-diol esters (3-MCPDE) and renal cancer in Peninsular Malaysia: exposure assessment and matched case-control study.

3-Monochloropropane-1,2-diol esters (3-MCPDE) are food contaminants commonly found in refined vegetable oils and fats, which have possible carcinogenic implications in humans. To investigate this clinically, we conducted an occurrence level analysis on eight categories of retail and cooked food commonly consumed in Malaysia. This was used to estimate the daily exposure level, through a questionnaire-based case-control study involving 77 subjects with renal cancer, with 80 matching controls.
