They may not notice that they have consumed spoiled food in many of the food poisoning cases. They may have knowledge about food safety, so good hygiene practices of food handlers can make sure that they do not harm by the food that can cause illness to them. It is the responsibility of the food handlers to reduce the risk of food poisoning among school children. The importance of personal hygiene in preventing the dispersal of microorganisms via various food contact surfaces has been demonstrated in various studies. As there has been no data has been published on food handlers hand hygiene practices in primary schools in Malaysia, this study is crucial to determine the knowledge of food handlers in good personal hygiene practices.
