The main objective of this study was to isolate, identify and
enumerate the E.coli O157:H7 bacteria and coliform bacteria from
locally manufactured soft cheese.
A total of 50samples of local soft cheese were collected and examined
from local markets of (5) different areas of Baghdad city which was { Aldora,
Al-Amria,Al-Kadmia,Al-Karada,Al-Kazalia} 10 samples for each
area.
The results showed that the highest average counts of E.coli O157:H7
and coliform bacteria was in Al-Dora 73.63 × 105and 956 × 105cfu/ml
while the lowest average counts in Al-Kazalia 3.12× 105and 43.7×
105cfu/ml .
The result of the statistical analysis showed that there were a significant
differences (p<0.05) between E.coli O157:H7 and coliform bacteria
between Al-Dora and the other areas in this study which was {Al-
Kadmmea,Al-Karada,Al-Ammrea,Al-Kazalia} but there were no
significant differences (p<0.05) between the tow kinds of bacteria in
each area.
It was conducted that the higher average of pollution for locally soft
cheese with E.coli O157:H7 was in Al-Dora , the reason of this higher
pollution may be due to un healthy condition during milk collection used
for milk processing or during the processing itself
