INTRODUCTION :
Swab Sampling and analysis was conducted in a vehicle at the premises of Packaging
Centre Services Sdn Bhd, Lot 6065, Jalan Haji Abd Manan, Batu 5 ½, Meru, 41050
Klang, Selangor.
2.0
PURPOSE :
The objective of this study is to evaluate the efficiency of the fogging exercise prevailing
in the ambient and surface environment within the allocated area.
3.0
ANALYSIS PROCEDURE :
The swab sampling for microbial organism was conducted using a sterile swab and sterile
distilled water for getting moisture condition. Upon swabbing the surface area selected
for sampling, the swab is taken back to the laboratory incubation of test media sampled to
promote colonies growth.
a) Incubation for Total Bacteria Count using Tryptic Soy Agar (TSA) @ 35oC, 48
hours.
b) Incubation for Total Yeast & Mould using Sabauroud Dextrose Agar (SDA) @ 25oC,
5 days.
At the end of the incubation cycle, each plate would be observed for any bacterial and
fungal growth in the form of colony forming units (cfu). Interpretation of the results are
based on the number of colony forming units that were present and counted on the media
plates at the end of the incubation cycle.

CONCLUSION :
Based on the laboratory data as obtained from the validation of microbial count in colony
forming units (cfu/swab) when compared with the pre and post fogging results, it was
noted that the fogging was successful in lowering the bacterial count in the vehicle
concern.
