One steamroller took an hour to crush nine tonnes of cheese. The country has also steamrollered fruit and burnt a huge pile of bacon.
Boxes of bacon have been incinerated. Peaches and tomatoes were also due to be crushed by tractors.
The destruction has caused an outcry from anti-poverty campaigners who say it should have been given to the poor.
President Vladimir Putin signed the decree ordering the destruction of food which breaches sanctions last week, with the law due to come into force officially on Thursday. The products must be destroyed in front of witnesses, and the act should be captured on video, to preclude corruption.
