| description | ‘Keropok lekor’ is a popular street food and widely available in Terengganu. However, there is limited study on the
microbiological status of sources of contamination from ‘keropok lekor’ premises in Terengganu. Microbiological quality of
raw materials and food contact surfaces were determined by Total Plate Count, coliform count, Staphylococcus spp. and
Vibrio spp. count. The presumptive of Escherichia coli, Staphylococcus aureus and Vibrio spp. were further identified by
phenotypic identification such as IMViC tests and API20 NE identification system. The antibiotic resistance of the identified
bacteria was determined using disc diffusion method. Escherichia coli and Vibrio were predominant microorganisms isolated
from raw materials, whereas Staphylococcus was the predominant microorganism on food contact surfaces. The boiling process
of ‘keropok lekor’ at 100°C was significantly (p < 0.05) reduced the Total Plate Counts, coliform, Staphylococcus spp. and
Vibrio spp. count for safe consumption. The identified antibiotic resistance of E. coli, S. aureus and Vibrio spp. showed that
the bacteria were within controllable emergence strains, whereby the present antibiotics used are able to suppress the growth.
Regular monitoring programme is essential to further improve the microbiological quality of raw materials and food contact
surfaces. |
