prevalence of Salmonella 240 samples were collected across District Mianwali. Out of 240,
eighty samples were of commercial eggs, eighty were of non-commercial eggs and eighty were of
egg storing tray samples collected from local markets and house farms of District Mianwali.
Selective media used for Salmonella was Hektoen enteric agar. Incidence of Salmonella in egg shells was 32.5% and 27.5%, in egg content was 15% and 12.5% and in egg storing trays was
40% and 32.5% in samples of commercial eggs, non-commercial egg samples and samples of
trays used for egg storage that were collected from local markets and house farms respectively.
Salmonella prevalence was highest in tray samples and lowest in samples of egg content in both
sampling sites. Salmonella prevalence in albumin and yolk was 15%, 12.5% and 10%, 5% in egg
content of commercial eggs and non-commercial eggs respectively. Overall Salmonella
