Abstract: With the progress of the times, the food container and detergent use for clean food and containers, continually change and innovation. At the same time human beings enjoy the food, it is often ignored potential hazard of the containers and detergents. Poor product manufacturing and improper use, it has possibility to causes contamination. The migration or residues may become a hidden worry of food sanitation and safety. According to the ‘Act of Governing Food Sanitation’, food detergents are defined as the substances which can be utilized to clean food, food containers, appliances and packing. The usage of detergents is needed for the dish cleaning and it is directly relative to the safety of food. There are many different kinds of food detergents which are commercially available. However, people’s health might be affected by the detergents if the ingredients include arsenic, heavy metals (lead, for example), methanol and nonylphenols. In order to promote public health and also to improve the quality of living, residual analysis for food detergents is a must.In this study, residual analysis will be performed to assess the health risks possibly caused by methanol, heavy metals, and nonylphenol. Since there is currently not enough information regarding the sources and ingredients of materials which are used to produce various detergents in Taiwan, efforts will be made to fill the knowledge gap. Besides, triclosan, formaldehyde, and 1,4-dioxne will also be measured to determine whether they appear in detergents. Experts from governmental agencies and manufactures will be invited to join a special forum to initiate the criteria for detergent certification in the future.Exploring the risk sources of healthy hazards for 『Food contact objects and materials』, the risk can be categorized as following, most are the material formulation, manufacturing processing and use behaviors. Each categorizes are possible to increase the risk of hazards for the food contact object. In this case, it needs to continue to assess the risk or preventive aspects. In the circumstances that other countries have banned the plastic baby bottle with containing Bisphenol A. Other plastic materials have been found in instead. Therefore, the project will be further investigation the commercially available plastic baby bottles while also conducting research and analysis for『potential hazard factor』 of the material formulation, Understanding of various replace materials whether necessary to management in the future.The domestic industrial structure is different from other countries. More than 97% are small and medium-sized enterprises. Current demonstrate the voluntary good manufacturing practice (GMP) does not apply to small enterprises. Therefore, it need to develop a suitable 『Food good hygienic practices』 (GHP) with the exemplary counseling to meet the requirements of GHP. Analyze many plastic food containers and packaging with unsafe events can be found. Usually, the consumers, food industry, even the teachers and students of the campus are unable to judge the scope and use limitations of plastic products. Through various types of activities to deliver and spread plastic food containers and packaging materials related knowledge in the project, to achieve a combination of effects.
