Russia has banned pork imports from two Farmland Foods plants, in what is becoming a drawn out case of interrupted trade.  The bans will take effect July 8 and affect Farmland's pork plants in Denison, Iowa, and Monmouth, Ill., reports Meatingplace.com

The country has also closed off poultry imports from a Sanderson Farms facility in Laurel, Miss., according to USDA's Food Safety and Inspection Service.

The agency reported that the current bans are a result of what the Russians stated were findings of residuals, or antibiotics, in products from these plants. "The level of tetracycline reported by Russia is not a violation of U.S. standards," noted an FSIS spokesperson.

Russia has been an ongoing challenge in terms of pork trade in recent months. Since the April discovery of Type A H1N1 influenza virus in the human population and its mislabeling as "swine flu," Russia and China both closed off shipments of U.S. pork. This action continues despite the health community's, including the World Health Organization, efforts to advise countries and the global population that the influenza virus is a respiratory disease and is not transmitted via pork.

The U.S. pork industry, the U.S. Meat Export Federation and the federal government have all been working diligently to engage Russia and China in trade discussions in an attempt to re-open these markets.
