Abstract:
Poultry is a major fast growing source of meat in the recent world. The consumers
want a contamination free, safe and hygienic meat, which is free from any type of
hazardous organism. This study has been done to find out the prevalence of
Escherichia coli in different markets. The markets were different live bird markets
and supermarkets. Also this study indicates the difference of Escherichia coli
prevalence between live bird markets and the supermarkets in Dhaka city,
Bangladesh. Samples from different markets were analyzed to determine the
pathogenic bacteria Escherichia coli. It was isolated from the dressed meat sample of
chicken through conventional cultural method. The samples were collected from
twelve markets. Seven of the markets were live bird markets and other five were
supermarkets. The markets were indicated as M1, M2, M3 etc for advantage while
sampling. The markets were Savar Hut (M1), Shemulia Bazar (M2), Bagbari Bazar
(M3), Bihari Camp (M4), Krishi Market (M5), Gigatola Bazar (M6), Taltola Bazar
(M7), and Supermarkets were (M8), (M9), (M12), (M11) & (M10). From each market
three samples were collected (S1, S2, S3). Result of this study demonstrated that the
prevalence of E. coli was more in live bird market than the supermarkets. The average
CFU/ml in live bird markets was 1.17534 × 10
12
and the average CFU/ml of
supermarkets was 3.37327 × 10
11
. The E. coli prevalence percentage of live bird
markets was 80.95% and in supermarkets it was 46.67%. So the pathogenic organism
in the consumed meat of this type is alarming. This study also concluded
recommendations that the personnel hygiene is crucial in processing and handling of
poultry and poultry products.
