Crabs or pesticide residues
At the CDC's booth in Jiangsu Province, 3 contrast foods were placed. The color of the paprika without Sudan Red was yellowish, and the Red Sable was red with Sultan Red; the yellow fish without dyeing was black, and the caudal fins were yellow after dyeing.
“A lot of people think that the good things are true. In fact, it is very likely to be stained.†Liu Hualiang, deputy director of the Center for Psychology of Disease Control of Jiangsu Province, gave reporters two red tables with 10 years of " List of illegally added non-edible substances in food." For example, pot bottoms and snacks may contain poppy husks, and this year's industrial gelatine, which has been buzzing, may also appear in ice cream and pork skin.
Most surprisingly, crabs may contain sodium pentachlorophenol. Liu Hualiang explained that sodium pentachlorophenol is more common in aquaculture and can eliminate harmful organisms such as oncomelania and grasshoppers. It can also be used to remove trash fish. “The adsorption capacity of river crabs is relatively strong, and there is also sodium pentachlorophenol in meat. â€
It is said that the National Day is a good time for crabs. Is there any way to remove sodium pentachlorophenol? Liu Hualiang gave a good idea - sodium pentachlorophenol is a kind of pesticide residue dissolved in alkaline water, so the crab should be soaked in soda water.
