The risk communication method for pesticide residues was examined. The examined method was evaluated by analysis of a questionnaire conducted on participants before and after the risk communication event using Fisher’s exact test and logistic regression analysis. The risk communication method consisted of a 65-min lecture with a 10-min break in the middle followed by a 15-min question-and-answer session. The lecture material consisted of the effectiveness of pesticides in food production, risk assessment of pesticides, and risk management of pesticide residues. Analysis of the questionnaires revealed that this risk communication method significantly promoted participants’ understanding of pesticide residues. This method also decreased the number of participants with a negative image of pesticides and increased the number of participants with a positive image.
