A collection of 60 convenience samples of balsamic vinegar products were collected and analyzed for arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb). Products included balsamic vinegar, balsamic vinegar glazes and reductions, and a balsamic vinegar dressing. The use of FDA’s Elemental Analysis Manual (EAM) 4.7 was implemented, which included using microwave assisted acid digestion followed by quantification using an 8800 inductively coupled plasma-mass spectrometer (ICP-MS). As concentrations ranged from 1.95 – 42.0 ppb, with a mean of 8.33 ppb. Cd concentrations ranged from 0.204 – 2.73 ppb, with a mean of 0.668 ppb. No quantifiable levels of mercury were detected. Pb concentrations ranged from 2.45 – 138 ppb with a mean of 27.8 ppb. Pb and As were the predominant toxic elements found in the samples analyzed, with quantifiable levels found in 95% and 65% of the samples,respectively.
