- Abstract
This study was performed to assess the potential for exposure to some potential pathogens in table eggs from 34-week-old ISA Brown laying hens in Algeria. The study was conducted in two different laying hen houses and included a total of 504 eggs collected randomly during two distinct seasons, winter and summer, and stored at room temperature and refrigerated for 30 days. The bacteriological analysis of the different germs for the eggs collected in the winter season did not reveal any bacterial contamination for all eggs stored at room temperature and refrigerated. In the summer season, no bacteria were found in eggs kept at refrigeration temperature. Therefore, for total germs, the peak of contamination was observed for D14 eggs (3.09 Log CFU/g). No fecal coliform bacterial contamination was observed at D0 and D7. A peak fecal streptococci contamination was observed for eggs aged 21 days (2.88 Log CFU/g), and similar values were also observed for D7, D14, D30, these being of the order of 2.49, 2.48 and 2.47 Log CFU/g, respectively. Only for 30-day-old eggs, coagulase-positive staphylococci were detected with a minimal contamination of about 1 Log CFU/g. These results provide useful indications on the sanitary level of the hens and the state of hygiene on the farm.
