Aiming at international competitiveness of the Brazilian dairy sector, new governmental policies were released to improve quality and safety of bovine milk. In this context, it is important to quantify essential and toxic chemical elements. Here, the composition of milk samples taken at 32 dairy farms in Minas Gerais State was assessed by instrumental neutron activation analysis (INAA) and inductively coupled plasma mass spectrometry (ICP-MS), besides the evaluation of usual quality parameters. Significant differences were found for Ba, K, Na and fat content amongst dairy farms with diverse quality levels established on basis of somatic cell and total bacterial count.

The authors are thankful to the State of São Paulo Research Foundation (FAPESP) for the financial support, to IPEN/CNEN for the irradiation of samples with neutrons and to people who participated in the sampling and analyses, particularly the chemist Ms. Iolanda A. Rufini, responsible for sample digestion.
