Abstract:
Paralytic shellfish poisoning contamination is a threat to human health. Based on review of research articles pertaining to paralytic shellfish poisoning contamination in shellfishes and assessment of dietary exposure to paralytic shellfish poisoning in coastal cities of China from 2007 to 2022, the article describes the status of paralytic shellfish poisoning contamination, influencing factors and dietary exposure assessment in different sea areas of China (Bohai Sea, Huanghai Sea, East China Sea and South China Sea), and the relatively high-level contamination of paralytic shellfish poisoning in shellfishes is found to strongly correlate with red tides caused by season and water temperature in the Bohai Sea and South China Sea areas. Acute exposure assessment based on point estimate model is commonly used for assessment of dietary exposure to paralytic shellfish poisoning, and the risk of human dietary exposure to paralytic shellfish poisoning is within the acceptable range in most areas. Intensified monitoring of paralytic shellfish poisoning contamination in shellfishes and full consideration of parameters like processing factor during dietary exposure assessment are required in the future to allow more precise results.
