It is. Supposedly its safe to feed fescue hay to pregnant mares until
three months before foaling.( But I've heard doubts about this). You can
get certified fungus free fescue seed, but the hay guys I've talked to say
its not as strong growing as regular fescue, and don't plant it as a rule.
It isn't in all fields...in other words you can have a field of fescue
that is fungus free, while right down the block you can have a field full
of the endotoxin. If you're not breeding, tho, its not a problem. Around
here its hard to get hay other than fescue, and I import an orchard grass
fescue mix. I have one pony that picks through it and discards the fescue.
The other 8 eat it all. So go figure.

        Late gestation mares  on fescue  may have prolonged gestation,
thick placentas, ***s, weak foals, and/or agalactia. This is from
tha associated endophyte. (An endophyte free varitey of fescue
exists, but is lesss hardy--the endophyte appears to be  a symbiont.)
        Hay is also affected.

        Removal of mares from fescue 30-60 days before expected
parturition is apparently effective. In cases where this is
impossible, there is a drug which seems to block the action of the
toxins, but the name escapes me at the moment.

They are making fescue seed that is endophyte free (see the back cover of
most major horse mags this month). Also there is medication available to
give mares and foals that reverses the problems with endophyte infested
fescue grass.
