According to the European Union's regulatory standards for the management of chlorate and perchlorate (2020), it is necessary to establish test methods for the risk assessment and safety management of chemical substances that can contaminate food in natural or artificial environments. The Investigation is aimed to assess the contamination levels of chlorate and perchlorate in domestically distributed food.
Chlorate and perchlorate are by-products that occur in factory manufacturing processes or disinfectants, and they can flow into the food through waste water and sterilized cooking utensils. Potentially these are leading to indirect intake through food consumption. Due to their potential effects on various functions in human body, such as thyroid dysfunction, it is necessary to examine the levels of chlorate and perchlorate in domestically distributed foods.
To monitor the contamination levels of chlorate and perchlorate in domestically distributed livestock products, we selected pork belly as a high-fat food and milk as a representative liquid food for representative livestock food item.
The extraction and analysis method were estabilshed to measure chlorate and perchlorate contamination level. Based on the QuPPe (Quick Polar Pesticides extraction) method, a extraction process was modified through changing filter and shaking time. To achieve optimal analysis, the column and solvent mixture gradient was changed.
