In Japan, the Positive List (PL) system was introduced (Enforcement: June 1, 2020) in the regulative field of Food Apparatus, Containers, and Packaging (ACP) by the recent amendment of the Food Sanitation Act. Under this situation, continuous requests for the risk assessments from the Ministry of Health, Labour and Welfare (MHLW) to the Food Safety Commission of Japan (FSCJ) will be expected. To enhance fairness and transparency and to clarify the data required for the risk assessment, the FSCJ established its “Guidelines for the Risk Assessment of Food Apparatus, Containers, and Packaging” on May 28, 2019. The Guidelines apply to new Food Contact Materials or Substances (FCMs) after enforcement of the PL system (June 1, 2020). The subject material is synthetic resins, because the PL system was first introduced to them in Japan. In general, the substances that are migrated from ACP are not intended to migrate into foods, and their technological effects on foods are not expected. It can be supposed that the migration of these substances is generally very limited. Therefore, as adopted in the USA and the EU, the Guidelines also adopt the tiered approach for the toxicological data requirement that depend on the estimated migration levels (Tier of Dietary Concentration (Tier of DC)) on the subject substance. The greater the exposure to the substance through migration, the more toxicity test results will be needed. The risk assessment steps by the tiered approach in the Guidelines are (1) migration assessment, (2) toxicity assessment, (3) exposure assessment, and (4) risk characterization. These steps are aimed to harmonize with the general 4 steps of risk assessments: hazard identification, hazard characterization, exposure assessment, and risk characterization. In this review, we will introduce the overview of the Guidelines and details of the above 4 steps.
