Microbiological evaluation of poultry sausages stored at different temperatures
Keywords:quality, poultry sausage, meat product, shelf life, microbiological quality
The aim of our study was to evaluate the microbiological quality of poultry sausages, which were stored at different temperatures (4 °C, 15 °C). Total count of bacteria, coliform bacteria, yeasts and filamentous microscopic fungi were detected in poultry sausages. Microbiological quality was evaluated using the horizontal method for the determination number of microorganisms. Total count of bacteria in sausages stored at 4 °C ranged from 1 × 101 CFU.g-1 in sample 1 (after opening) to 4.35 × 104 CFU.g-1 in sample 1 (7th day of storage). Total count of bacteria in sausages stored at 15 °C ranged from 3.25 × 103 CFU.g-1 in sample 1 (after opening) to 3.12 × 106 CFU.g-1 in sample 1 to 3.12 × 106 CFU.g-1 in sample 1 (7th day of storage). Coliform bacteria in sausages stored at 4 °C ranged from 1 × 101 CFU.g-1 to 3.15 × 105 CFU.g-1. Coliform bacteria in sausages stored at 15 °C ranged from 1.54 × 103 CFU.g-1 to 1.40 × 106 CFU.g-1. Yeasts and microscopic filamentous fungi in sausages stored at 4 °C ranged from 2.75 × 104 CFU.g-1 to 1.40 × 106 CFU.g-1. Yeasts and microscopic filamentous fungi in sausages stored at 15 °C ranged from 1.30 × 104 CFU.g-1 to 1.44 × 106 CFU.g-1. Total count of bacteria, coliform bacteria, yeast and microscopic fungi were not in accordance with Codex Alimentarius of Slovak Republic on 3rd day in samples stored at 15 °C.
