A histamine concentration level in selected milk products, available through retail networks, was determined using a colorimetric method. The results obtained proved varying histamine concentration levels in milk products, tested directly after the milk was purchased. The highest histamine concentration level was stated in the low-fat milk powder (3.18 mg/100 g), followed by the UHT cow milk (2.51 mg/100 g), the UHT goat milk (2.29 mg/100 g), and the pasteurized cow milk (1.55 mg/100 g). The lowest histamine concentration level was found in the non-pasteurized goat milk. (1.24 mg/100 g). While 96 h storing the pasteurized and the UHT milk at cooling (3±1°C) and ambient (18±2°C) temperatures, it was stated that after the initial increase in the histamine concentration, its level decreased.
