From the Daily Telegraph:
US authorities are considering relaxing an import ban on the Scottish delicacy, brought about by the BSE crisis in 1989, it was reported.
The meat dish contains offal, including sheep lung, which was covered by the American restriction on some imported animal products.
...
A spokeswoman for the United States Department of Agriculture told theSunday Times newspaper it was reviewing its regulations in line with a ruling from the the World Organisation for Animal Health (OIE) that sheep lung is safe.
The spokeswoman said: ''At this time, there are regulations being drafted.
''By closely aligning our import rules with the OIE, we will allow the importation of certain ruminant products that do not contain tissues associated with BSE infectivity or ruminants raised under conditions where they were not fed prohibited materials associated with spreading BSE.''
This may be a good example of how the SPS Agreement works outside the context of disputes. Sometimes governments actually just comply with the rules.
