On April 9, Zhao Pu, a well-known CCTV host, posted on Weibo: "A text message from an investigative reporter: Stop eating old yogurt (in solid form) and jelly. Especially for children, the inside story is scary. "I won't go into details." Media person "Zhu Zhu Wenqiang" also posted on Weibo, "A CCTV guy said, don't eat jelly and yogurt in the future. When asked why, he said metaphorically, one day you throw away a pair of broken leather shoes, and in the blink of an eye it will be over. It’s in your stomach.” "Zhu Zhu Wenqiang" also said: "This is the highlight of this year's March 15 party, but it is a pity that it was not broadcast." After Weibo was posted, some netizens speculated that Weibo was referring to the thickener in old yogurt and jelly, which may be industrial gelatin refined from leather. On the evening of the 9th, both Zhao Pu and "Zhu Zhu Wenqiang" deleted the relevant Weibo posts.
