Abstract:
A study was conducted to determine the incidence of Salmonella enterica serovar Enteritidis and other Salmonella serovars on
eggshell, egg contents and on egg-storing trays. A total of 492 eggs and 82 egg-storing trays were examined over a period of 1 year
from different retail outlets of a residential area of Coimbatore city, South India. Salmonella contamination was recorded in 38 of
492 (7.7%) eggs out of which 29 was in eggshell (5.9%) and 9 in egg contents (1.8%). Around 7.5% of the egg-storing trays were also
found to be contaminated with Salmonella. Serotyping of the Salmonella strains showed that 89.7% of the strains from eggshell,
100% of the strains from egg contents and 71.4% of the strains from egg-storing trays were Salmonella Enteritidis. Other
serovarvars encountered were S. Cerro, S. Molade and S. Mbandaka from eggshell and S. Cerro from egg-storing trays. Seasonal
variations in the prevalence pattern were identified with, a higher prevalence during monsoon months followed by post-monsoon
and premonsoon. Further examination of the Salmonella strains was carried out by testing their antimicrobial sensitivity against 10
commonly used antimicrobials. Results revealed high prevalence of multiple antimicrobial resistance among these strains suggesting
possible prior selection by use of antimicrobials in egg production
