Lord McNairLord McNairasked Her Majesty's Government:
In which counties of the United Kingdom are cattle significantly affected by warble fly.
Lord LucasNo clinical evidence has been discovered to suggest that warble fly is currently present in the United Kingdom. While the test results from our 1994/95 serological survey suggested that warbles might be present in small numbers of cattle throughout Great Britain, the absence of clinical cases did not support this position. One clinical case was discovered in an imported animal but this was returned to the country of origin.
