- Abstract
Background: Milk and dairy products are the main sources of essential nutrients particularly for children. However, milk and dairy products can be contaminated with chemical hazards and contaminants which pose serious health risks for consumers. These toxic compounds are entered into the food chain through contaminated soil, water, and air and their presence even at low levels would result in metabolic disorders. Objectives: The aim of this study was to determine the level of lead in pasteurized milk and different dairy products in highconsumed brands in Tehran. Methods: A total of 38 samples (18 pasteurized milk and 20 dairy products from the most-consumed brands) were analyzed using graphite furnace atomic absorption spectroscopy for quantification of lead level. Hazard quotient (HQ) and carcinogenic risk (CR) were used to assess health risk and carcinogenic risk. Results: The results showed that the levels of lead in all pasteurized milk samples and dairy products were below the allowable limit. HQ was less than 1 in all samples and CR was in the range of 10-8 to 10-7 and both were at acceptable levels. Conclusions: It can be concluded that there was no risk of carcinogenicity in pasteurized milk samples and dairy products for children and adults. However, due to the higher consumption of milk by children and their greater susceptibility, the level of heavy metals should be monitored by health agencies.
