The May 23, 2011, plasticizer incident was one of the most serious food safety issues that ever occurred in Taiwan. Most, if not all, plasticizer-contaminated food items were due to malicious replacement of palm oil with phthalate plasticizer(s) in the cloudy-agent formulas by two upstream manufacturers. The incumbent agencies in Taiwan took necessary actions to minimize the harm caused by the incident and to ease the panic of the general public. In this paper, the incident was briefly reviewed and the situations of phthalate exposure in general public and pregnant women were assessed. Subsequently, the associations between phthalates exposure and the adverse health effects, such as shortened anogenital distance in baby boys, premature thelarche in young girls, endometriosis, adenomyosis, and leiomyoma in women, and decreased semen quality in men, were discussed. Food safety issue has become a worldwide concern and early detection of potential new toxicants in the foods is indispensable. Therefore, it is imperative to establish an international network for early warning or sentinel on food safety.
