Now I have never made my own haggis, but I saw an episode of bizarre foods where they were making them (not sure why it was on that show at all). All the meat was cooked prior to being ground together and mixed with the oatmeal. Wouldn't that cooking process in effect sterilize the lungs? I know that food only has to be kept above 140 degrees to be served here.

As an aside, on a science fiction forum I frequent we were discussing alien food as seen on TV. One dish was was a type of lung. A poster from the UK said that lungs were declared inedible in the UK too. Now I know she is in England, but I would think food regulations would be the same. Is this true or is it more British propaganda?
