In Malaysia, most of the reported cases of food poisoning occurred in public school
canteen and because of that various efforts are made by Malaysian government to
improve food safety practice in school canteen. However, despite the efforts the
number of food poisoning cases still reported today. The food handlers in the
institutional foodservice such as public school canteen must follow the proper food
safety practice to prevent the outbreak of foodborne diseases. Addressing the hand
washing practices is one way to improve food safety practices. It has been reported
by prior studies that food handlers in Malaysia have low compliance rate of hand
washing practices. And, there are lack of intervention studies to improve food
handlers hand washing practices especially in Malaysia. Most of food safety
intervention studies more focused on knowledge, although there are many possible
factors beyond knowledge that affecting food safety practices. Therefore, the main
objectives in this study is to develop hand washing intervention based on factors that
affecting food handlers hand washing practices. Among others the objectives in this
study is to elicit the beliefs of hand washing practices among food handlers and to
identify specific factors that influence their hand washing practices. To achieve the
objectives, this study employed mixed-methods approach which involved phase one
and phase two. In the Phase One, a series of seven focus group discussions were held
with food handlers from school canteen to assess food handlers’ beliefs on the hand
washing practices at their workplace. The guide questions based on The Theory of
Planned Behavior was employed during focus group discussion and the themes
emerged were categorized according to the theory framework. Next, phase two
involved survey and development of intervention. Findings from focus group
discussion were used in survey instrument development. Then, a survey was
conducted with 83 food handlers from public school canteen. The PLS-SEM
analysed of survey revealed that only subjective norm significantly and positively
predicts the food handlers’ intention to perform proper hand washing practices based
on the path coefficient of 0.748 (p<.001). These suggests that food handlers’
subjective norms (e.g. manager, school administration, customer, co-worker, health officer) positively influence the food handlers hand washing practices. The
development of intervention was continued afterward by incorporated the subjective
norm factor and feedback performances was developed as main intervention with the
integration of poster reminder and installation of soap and paper towel dispensers.
The effectiveness of interventions was measured through the direct observation of
food handlers hand washing practices in control group and intervention group during
pre and post observation. The results of interventions do not significantly improve
the hand washing compliance rate of food handlers. This could be due to various
factors that affect interventions such as the way feedback performance were given,
habit of food handlers and absent or lack of food safety culture in food handlers’
workplace. Although the implemented interventions do not improved hand washing
compliance rate among food handlers, the finding still provides a valuable
information to the management of school canteen, school administration and public
authorities in their efforts to improved food safety practice in general and hand
washing practices. |
