Inactivation of Campylobacter jejuni (strains No. 6, 19, and 34) was determined in poultry meat pressurised under the following conditions: at 300 MPa for 5, 15, 30, and 60 min, and at 500 MPa for 5, 15, and 30 min, at 20°C. The pressure treatment of 300 MPa applied for 5, 15, and 30 min did not inactivate all cells of the analysed C. jejuni strains. The inactivation of all C. jejuni cells occurred...
This stiřdy was aimed at determining the influence of three different freezing methods on the horsemeat microfloraduring a 3-month-cold storage. The three methods used included freezing in a container ventilation chamber, freezing in liquid carbon dioxide and two-stage freezing method (combined method based on using liquid carbon dioxide and freezing in a container ventilation chamber). The study...
Samples of milk were examined for the presence of microbiological contaminations and antibiotic residues and other inhibitory substances. Out of 281 samples under study aerobic bacteria were found in 40 samples and E. coli titers were higher than those which are commonly accepted in 56. The presence of antibiotic residues and other infibitory substances was tested by means of two methods, i.e. Delvotest-SP...
