“…This novel approach can contribute to the body of the knowledge on consumers’ risk perception-behaviors by overcoming a limitation of relevant research which have been conducted as the singular cross-sectional study for specific time-point [ 2 , 21 , 25 , 26 , 27 , 28 ]. Comparative analysis of multiple individual surveys conducted in different time-points was rarely reported from the research not only for consumers [ 1 , 21 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ] but also for food handlers in food services [ 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ].
