As the World Health Organisation says the swine flu outbreak has moved closer to becoming a global pandemic, a number of states have put a ban on the import of pork from affected countries.
China, Russia and South Korea have banned imports of some North American pork, despite assurances that the flu is not spread through meat.
This includes imports from the United States, which is one of the world's biggest pork exporters.
The pork industry is a very big part of economies in the midwestern states like Nebraska.
Roger Hearing asked John Hansen, president of the Nebraska Farmers Union how the current swine flu outbreak was affecting his state.
