Ridecamp: [RC] equine tape worms (ugh!)

Here in Northern CA we've recently heard of an epidemic of tapeworms in 
horses, due to a warm winter not killing the eggs and horses grazing same 
forage and "sharing the wealth".  Initial diagnosis apparently was made after 
one mare was "off" and intermittently kicking at her belly.  New fecal test 
available, as I understand it (third hand, by the way)  by the manufacturer 
of Strongid, and recommended treatment was 2 doses of the Strongid paste.  
This mare was on the Strongid daily formula at the time of diagnosis.  
Ensuing tests on other horses at the same boarding facility have 
ALL been positive...
Seems like a high percentage but I don't recall having heard of this before 
so am looking to the expertise of RideCamp for more information.....Thanks!
