Abstract

This paper contains the observations which where found during the study of microbiological risks in two phases of technological process in production of pork meat (2 hours postmortem, before going into the chamber, and 24 hours post-mortem, immediately after leaving the chamber). These two markers are viewed as possible CCP and/or CP as part of the project of implementation of HACCP in this meat industry. The total number of aerobic mezzophilic bacteria on a carcass 2 hours post-mortem is on average 120/cm2, expressed as an average value of the total number of aerobic mezzophilic bacteria which were got by means of standard and quick methods, while in the second marker 24 hours post-mortem it is 70/cm2; the total number of Enterobacteriaceae 2 hours post-mortem is on average is 4/cm2, while in the second marker 24 hours post-mortem it is 3/cm2; the frequence of Salmonellae is 12,5%, and Escherichia 7,5% on the total number of samples. A bit larger number of aerobic mezzophilic bacteria is justified since thermically non-processed meat was observed while the presence of pathogenes can be a marker of insufficiently and irregularly applied hygienic and technical-technological aids of protection.
