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. Samples were digested using a microwave before analysis with inductively coupled plasma mass spectrometry (ICP-MS). Pb was determined, highest in cattle lung (0.11 ± 0.20 mg/kg) followed by cattle spleen (0.09 ± 0.14 mg/kg), and cattle tripe (0.09 ± 0.12 mg/kg). For Cd, the highest concentrations were in cattle liver (0.13 ± 0.12 mg/kg), pig liver (0.08 ± 0.05 mg/kg), and chicken liver (0.03 ± 0.02 mg/kg). Significant variations of Sn levels existed in different canned food categories with 3.21% samples ( n = 7) exceeded the maximum level of 250 mg/kg set by Codex Alimentarius . All offal samples were below the Malaysian regulatory limits, indicating their safety for human consumption. However, Sn levels varied significantly among canned food categories, with the highest levels found in canned pineapple chunks in syrup, mixed pineapple cubes in syrup, pineapple slices and longan. Samples exceeding the maximum level set by Codex Alimentarius may pose a risk to consumers. |
