Poisonous Shrub? Help please!!!

[Inchy]

I'm planning on planting a small hedge along the side of my fence seperating the horses from the garden. The shrub we are using is a Lonicera Nitisa or 'Baggesen's Gold'. I've had horses near it before and they have never been interested it in, but i dont want to plant it near the horses if it will be a problem. It'll be over a post and rail fence from them...but within reach.

I'm assuming it isn't poisonous as i haven't found it on any list of plants thats are poisonous to horses...despite extensive googleing!!

But if anyone knows, if it is or isn't poisonous i'd be very grateful!.

Thanks x
