What Is Already Known About This Topic?:
Fipronil is classified as a "possible human carcinogen" by the United States Environmental Protection Agency. Long-term exposure to fipronil may cause damage to liver, thyroid, and kidney. However, fipronil and its metabolites are ubiquitous in the environment and food.
What Is Added By This Report?:
The dietary intake of fipronil in China was within acceptable levels with low health risk. Eggs were the main dietary intake contributor of fipronil for Chinese adult populations (55.3%), followed by vegetables (30.7%), meats (5.90%), cereals (5.30%), and other food categories contributed less than 2%.
What Are The Implications For Public Health Practice?:
The study results will help health managers understand the health risk of fipronil, and help to better formulate monitoring plans in foods. It is still necessary to strengthen the monitoring of fipronil in foods, especially animal-derived foods.
