There were investigated 45 rennet cheese samples distributed on the retail market in the cities of Lublin (25 pieces) and Kielce (20 pieces). Three types of cheese were investigated: Edam (17 pieces), Gouda (16 pieces), and salami (12 pieces). All the types of cheese were fatty types and classified as class 1 according to the declaration of their manufacturers. The cheeses distributed in Lublin were manufactured by 15 various dairies, and the cheeses distributed in Kielce – by 10 diaries. On the basis of the evaluation results of organoleptic parameters of the cheese types, it was stated that there were many deviations from the standard parameters, especially with regard to the consistency, taste, and aroma. The dry matter (water) and salt content did not exceed the admissible standards. The analysis showed significant differences in the brightness (L*) and saturation of the yellow colour (b*). Cheese distributed in the retail network of the city of Kielce showed a lower brightness at a higher yellow colour concentration. This fact could indicate a higher addition of cheese-maker paint. The analysis of twenty five samples of the cheese in the Lublin retail network showed an excessive nitrate content in 3 cases (12%) and in 2 cases in Kielce (10%). The samples in Kielce also indicated an excessive nitrite content.
