The detection rate was significantly different in different seasons, sampling positions, species and processing methods and selling styles. The detection rate of VP (27.40%) was the highest in the third quarter of a year. The detection rate of VP (32.73%) was the highest in supermarkets of all sampling positions. The detection rate of VP (53.33%)was the highest in the freshwater crab of all species. The detection rate of VP (27.23%) was the highest in the fresh freshwater products of all kinds.
