Russia is tightening monitoring of imports of U.S. meat after reported cases of contamination of ground beef with E. coli at "Tyson Fresh Meats Inc." in Kansas. The latter plant has already withdrawn 60 tons of meat.

  The Russian sanitary service says the presence of E. coli in the meat was laboratory-confirmed on September 27, and the withdrawn product was produced on August 23rd .

  The consumer protection service Rospotrebnadzor did not specify where the infected meat products were exported.

  In the framework of the Customs Union the service has warned the sanitary services of Belarus and Kazakhstan to take precautionary measures.
