You may be right in what you say but up here farmers can be made to move cattle if they are grazing in a field full of ragwort. Also neighbours who have the stuff had to remove their horses and get it dealt with before being allowed to graze their horses. We used to be surrounded by it but now most of the farmers spray every year and keep it at bay. If you have experienced a horse dying from ragwort then you would never take any risk again. My vet is very experienced on this subject. You may think its rare but in the North of Scotland it happens in all grazing animals.
I don't just think that it is rare I know that it is rare because it has been studied and found to be rare. There have been people stating daft figures in the press but we know from all the studies carried out here and internationally that poisoning is rare.
If you look at the Dutch website I provided to you and investigate you will find that one of the co-authors is a scientist who actually has a Phd in Ragwort.
Ragwort poisoning is non-specific.All you see are the symptoms of liver damage which has lots of causes. When Post Mortems are carried out it is then often found that ragwort ISN'T the cause but most of the time they do not bother.
A scheme to check cases like this in the Netherlands has had no cases at all since 2007!
If people are being forced to move cattle because of the presence of ragwort then they should be forced never to let the cattle out in the fresh air. Why? because they probably have a greater risk of being struck by lightning. It is a daft idea to keep cattle away from rain but it is as daft as some of the claims about ragwort.
I wouldn't have much faith in the Scottish authorities on this matter. A few years ago they published a draft document on ragwort with a really bad howler of an error in it. They could not have made this error if they had even the simplest grasp of its toxicology.
