My point was more that this could be that it's bees which were legally imported, inspected and it was found thus can be stopped. Hence making sense of the line in the article that all affected hives have been isolated. This is different to someone not following the rules or failure to detect it leading to an outbreak. In fact, it would suggest that the inspection system used is working.
If SHB or any other exotic disease makes it to the UK, and gets past inspection to be able to spread, I agree with finding those at fault but in this instance, I'm not sure that's an accurate comparison.
