Well, John having been left the service for 9 years I don't know.
All that I know is that glass is safer from a contamination point of view and from a recycling point of view too.
You cannot get into a glass ampoule unless you break it.........but as Lettei has said it would be relatively easy to contaminte plactic vials with a fine bore needle, and you cannot see that it has been tampered with.
If they were still using glass ampoules, then the contamination would have had to have occured at the point of manufacture.
It is going to be really difficult to investigate.

And although it may be an NHS employee, it could just as easily be someone from outside.
I remember one guy who came to Blackburn, got himself a stethoscope and a white coat and spent time at Blackburn Royal conning people he was an anaesthetist(paul somebody or other...it will come back to me )People were shocked that this could happen.......but it did, and who is to say that it isn't somebody like this.
