This essay explores the representation of everyday risks and their avoidance through a Barthes’ semiotic analysis on the TV commercials of anti-bacterial products. After analyzing the expression type and the first- and second-order signification of anti-bacterial TV commercials representing everyday risks, the existence of risk appears as mood or feeling rather than specific and quantitative indicators such as numbers and is delivered to draw audiences’ sympathy. In addition, it is observed that a method for dealing with the risks, emphasizing its trustworthiness, is necessarily suggested in order to set audiences at ease. It is assumed that the audiences who recognize and deal with the risks in the commercials and purchase those anti-bacterial products is motivated for the well-being, and resultingly happiness, of family members rather than personal health. This shows the existing family norms are closely associated with the consumption of anti-bacterial products as a logic of risk management at the individual level. Based on current discussions in the field of risk communication, we attempt to explain the public concerns and avoidance of contagion in everyday life, shown in TV commercials and argue that interpersonal feelings are exchanged and social norms are reproduced in the risk communication process in TV commercials.
