dc.description.abstract | The study was conducted to evaluate the bacteriological contamination in indigenous
pork at slaughterhouses at Ho Chi Minh City. A total of 225 pork samples were collected
from 3 large-sized slaughterhouses, 3 medium-sized slaughterhouses and 6 smallsized slaughterhouses for detection of the total aerobic bacteria, Escherichia coli and
Salmonella. The detection of total aerobic bacteria, Escherichia coli and Salmonella
were based on the protocols of International Organization for Standardization (ISO).
The overall mean total aerobic bacteria of large, medium and small abattoirs were
5.8×103, 2.5×104, and 1.1×104 CFU/ml , respectively with a statistically significant
difference (p < 0.05). The mean of E. coli in large, medium and small-sized
slaughterhouses were 7.6×10, 1.1×102 CFU/ml , 4.9×10 without statistically
significant difference (p >0.05). Moreover, the level of Salmonella contamination at
medium-sized slaughterhouses was the highest compare to that at the large and small
slaughterhouses. The large-sized slaughterhouses had 80% tested samples that met
3 microbiological standards.
