also considered. A cross-sectional survey was conducted in 4-27 January 2014. Questionnaire

The majority of the participants agreed that reused cooking oil is the cause of health hazard
(88.10%). However, more than half of them possessed improper frying practice (52.38%)
because there were food operators did not use refined oil firstly each day (28.57%) or decided
for replacing or adding by the refined oil after the physical changes of using oil had been
occurred such as the using oil turned dark or emerged sticky bubbles (26.19%).
Although most reused cooking oil samples were acceptable in quality, there were no significant
