Similar to other UE countries, in Poland, legal regulations have been introduced on manufacturing and selling food products including, among other things, legal standards enforcing the obligation of implementing and applying some quality management systems. This, the use of GHP/GMP, and HACCP systems in the food enterprises, which manufacture and sell food products, is mandatory. Five years after Poland joined the UE, the number of enterprises, which have implemented and operated the obligatory quality management systems, significantly increased. Based on the monitoring carried out in a period from 2005 to 2009, it is concluded that, in 2009, the straight majority of enterprises (94 %) processing food of animal origin implemented the obligatory quality management systems. In the group of food enterprises processing products of non-animal origin, there were 88 % of enterprises using GHP, 85 % of enterprises using GMP, and only 32 % of enterprises using HACCP.
