Comparative Studies Concerning Microbial Quality of Ecological and Conventional Milk

The quality and safety of grocery became a consumers’ right that affects directly the quality of life. Thus, the issues referring to the safety of grocery is in the center of attention of the institutions created for protecting the customers’ best interests. The bio milk can be defined as milk with zero quality defects. This means that the milk corresponds to all quality criteria, respectively nutritional, sanitary, bacteriologic, technologic, sensorial, and psycho-social. The microbiological analyses that are described in the paper have the purpose of monitoring the microbiological parameters listed COMMISSION REGULATION (EC) No 1441/2007 of 5 December 2007 amending Regulation (EC) No 2073/2005 on microbiological criteria for foodstuffs and REGULATION (EC) No 853/2004 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 29 April 2004 laying down specific hygiene rules for food of animal origin. The research was made during the validity period of the 3 types of milk that were studied (eco milk, UHT milk, conventional) respectively the product in the first day of validity, in the middle of the validity period and in the last day of validity. The methods used represented both rapid and classic standardized techniques, using media of enrichment, isolation and confirmation, characteristic to each method. After the realised determinations referring to some microbiological characteristics of the conventional and ecological milk, through the validity period were observed some alterations related to the microbiological quality of milk.
