Introduction:

Milk and dairy products are nutritious and can play a significant role in a healthy diet. The safety of milk decreases with increasing concentration of arsenic. The Maximum Residue Limits of arsenic is 500 parts per billion (ppb).

Objectives:

To evaluate the status of arsenic contamination of milk and dairy products produced and processed in some provinces and cities of Vietnam.

Methods:

A total of 367 samples were tested. Samples were digested before analysis to remove organic compounds, and the total arsenic content determined by atomic absorption spectrophotometry.

Results:

The average concentrations of total arsenic in liquid milk were 139.32 ppb; in yogurt, 169.81 ppb; in cheese, 221.38 ppb; in milk cake, 232.80 ppb; and in milk powder, 35.43 ppb, respectively.

Conclusion:

The arsenic concentrations in some samples are higher than the maximum permitted levels according to national regulations.
