Food Safety Lab
Machine-translated · View original
The lab develops methods to measure pesticide residues and harmful substances in food.
AboutAbout the lab
Developing analytical methods that support food safety.
The website registered for this lab is the page of the Division of Foods at the National Institute of Health Sciences.
To contribute to food safety for the public, the Division of Foods develops methods to analyze pesticide residues, radioactive substances, natural toxins, heavy metals, and more in food.
The analytical methods it develops are issued as official test methods through public notices and notifications, and are used at quarantine stations and local public health institutes, among other places.
The lab also conducts research on measuring trace amounts of chemicals in food with LC-MS/MS and other instruments, as well as intake surveys using total diet study samples.
Key terms
- LC-MS/MS
- A measuring instrument that combines a liquid chromatograph with a mass spectrometer. It measures trace amounts of chemicals
- Total diet study samples
- Samples made from foods bought at markets. They are used to investigate intake of radioactive substances, heavy metals, and other substances
- Official test methods
- Test methods set out by the government through public notices and notifications. They are used at quarantine stations, local public health institutes, and other places
ResearchResearch themes
To contribute to food safety for the public, the Division of Foods conducts research on methods to analyze pesticide residues, radioactive substances, natural toxins, and more in food, with the work divided among its sections. It develops methods to efficiently extract, purify, and concentrate trace amounts of chemicals from food samples, and measures them with LC-MS/MS and other instruments.
*Illustrative imageAnalytical methods for pesticide residues in food
The lab studies and develops new test methods for pesticides, feed additives, and veterinary drugs for which new standard values have been set. To make testing more efficient, it also improves existing test methods and develops multiresidue methods.
*Illustrative imageAnalysis of radioactive substances and environmental contaminants
Using market basket samples and similar materials, the lab conducts survey research to measure radioactive substances in food and develops methods to detect irradiated foods. It also conducts research on environmental contaminants in food.
*Illustrative imageComponent analysis of natural toxins and health foods
The lab works on ensuring the quality of health foods, examining "designated ingredients" and developing analytical methods for them, and identifying the causes of health hazards. It also conducts research on food defense, such as countermeasures against food terrorism, and on the functional ingredients of foods with function claims.
*Illustrative imageIntake surveys of food contaminants
The lab collects data on intake of pesticide residues, veterinary drug residues, and contaminants in food, and conducts research on searching for contaminants. It also works on survey research and analytical methods for toxic metals and toxic elements.
