beet pulp reaction

[Gary Fend <garyfend@pacbell.net>]

We just had an unusual reaction to a new bag of beet pulp - thought I'd
see if anybody else had seen anything like this.
I brought three horses in from pasture for extras, they all got the same
hay, LMF and vitamins, but only two of them got a bucket of shredded
beet pulp (a new bag).  The next morning, the two with the beet pulp had
swelling around their throat latch area, and onto their cheeks.  No
temp, normal pulse, everything seemed fine, they acted fine, just
swelling.  It went down throughout the day, and by late afternoon, all
was well.
My guess is there was something else that got shredded in with the beet
pulp, but I'm looking for other input.  Any ideas out there?  I won't be
using that bag, and am considering taking it bag to the feed store to
let them know it might have been impure or tainted in some way.
Thanks,
Laura (and my "chipmunk" ponies)
