Estimation of heavy metal concentrations in imported frozen meat sold in the Libyan market

Heavy metals are chemical elements with a toxic effect on human and animal bodies. The expansion of industries has led to substantial increases in the levels of these heavy metals in the environment. This study examines the levels of heavy metal contamination in imported frozen meat, given its importance for food safety and consumer health. A total of 30 meat samples (including chicken, beef, lamb, and some processed products) were randomly collected from various commercial markets in Tripoli. Following acid digestion, concentrations of lead, cadmium, chromium, and copper were determined using Atomic Absorption Spectrophotometry. All samples complied with Libyan and International safety limits for cadmium, chromium or copper, while only one sample (3.3%) exceeded the permissible limit for lead. Statistical analysis revealed no significant variation in lead, cadmium, or chromium concentrations across meat types, cuts, or countries of origin. Copper levels, however, varied significantly by meat type. These findings indicate the overall safety of imported meat products regarding heavy metal contamination, although continuous monitoring remains essential.
