Verification of prediction of Growth of Listeria monocytogenes microorganisms in chicken meat

Popis výsledku v původním jazyce

A raw chicken was comminuted and homogenised. There were measured water activity and pH (aw=1 for temperature 25°C, pH=5,8 for temperature 8°C). Input raw material was investigated on Listeria monocytogenes micro-organisms occurence (negative) and inoculation was made by Listeria monocytogenes CCM4699 micro-organisms. Number of Listeria monocytogenes, total number of micro-organisms and Coliform micro-organisms were determined in range 0-7 days by microbial survey for storage temperatures 4,9, 7 and 8,3°C. The increase of CFU Listeria monocytogenes became for temperature 4,9°C about log CFU/g=1,5 after 6 days, for temperatures 7°C and 8,3°C about log CFU/g=2 (regarding starting counts). The prediction using Food MicroModel was also made. The best agreement between experiment and prediction was received for lowest incubation temperature 4,9°C.
