The only warning about horse manure is that there is some

could kill garden worms.

The worms in a horse's gut are not related to earthworms, though I
suppose a broad-spectrum vermicide could affect a wide range of
creatures.

When we still had horses, the vermicide we gave them was a broad
spectrum one. I dont' know if it would kill soil worms or not and
have only noticed that I get more worms after using the manure.
However, I have consistently read this as being a warning about using
fresh horse manure (especially sourced from racing stables) but I have
certainly wondered if it's just an old gardener's tale.

I have so often read of the 'need' to pile horse manure but I know
from experience that such isn't the case. I do lots of other thing in
my garden too that would be frowned on by garden purists but they work
so I often wonder about how we end up doing the things that we do.
For example, I've often planted into weed piles and that grows a crop
and I now plant all potatoes in a hay bed and that works too.
