That was not the case that prompted this reaction, so I don't understand the reasoning behind your comment?
The case that prompted this reaction is described in the first paragraph of the linked article. The one you refer to in the second one as an older case.
There is no mention of the older case having lead to any shutdowns, making it hard to follow your train of thoughts, since you specifically refer to this older case.
I believe the issue is that the kind of precautions they're using were based on some assumptions (e.g. that mouse prions do not affect humans) which were flawed and need to be re-evaluated. It's not just "don't cut yourself, duh".
Your reasoning seems backwards to me. If she had hurt herself through some unlikely and intricate series of events, a shutdown would have made less sense.
Its not rocket science.
