ABSTRACT
In the present study five heavy metals were analyzed in the milk samples of cow, buffalo and goat. The level of Pb was found to exceed the maximum permissible limit (0.02 µg/g) set by Codex Alimentarius Commission in 53% milk samples. In 44% milk samples the level of Cd was found to exceed the permissible limit (0.0026 µg/g) set by International Dairy Federation (1979). The mean levels of Ni, Cu and Co were found in the normal ranges. The data for estimated daily intake of heavy metals through milk showed that infants are most prone towards heavy metal toxicity due to the higher rate of milk consumption.
