To promote and raise the awareness of accurate knowledge on pesticide residues, the symposium program on risk communication on pesticide residues was held by the broadcasted online style. The risk communication program was statistically evaluated using a pre- and post-program online questionnaire survey. We had the questionnaire answers of the 105 valid participants. The analysis of post-program questionnaires shows that the risk communication program was effective in terms of levels of understanding and interest. Pre-program risk perception or awareness of safety assessments was significantly and positively correlated with awareness for establishing standard values of pesticide residues by the analysis of pre-program questionnaires. Risk perception after the program was significantly higher than before the program, suggesting that risk perception increased due to the program by analysis the same question between pre- and post-program questionnaires. Multiple regression analysis suggests that the participants with higher pre-program awareness of safety assessments or pre-program awareness for establishing standard values appeared to have higher levels of understanding and post-program risk perception.
