Rospotrebnadzor's decisions have proved controversial in the past. Its former head, Gennady Onishchenko, once suggested killing crows, describing them as feathered wolves which spread bird flu. He was also associated with banning food and drink imports from countries unpopular with the Kremlin. The agency's lice advice has been mocked by social media users in Russia. "Are they suggesting most young Russians have lice?" Georgy Klochkov asks on the Lenta news website. Another user says: "This is wonderful!! Onishchenko's work still flourishes - the more bonkers the reason, the better."
