Equine Grass Sickness
Equine grass sickness (EGS) is a frequently fatal disease of horses with a mortality rate in excess of 85%. EGS has been recognised for over 100 years since it was first reported near Broughty Ferry, Scotland in the first decade of the 20th Century. Great Britain continues to have the highest frequency of cases in the world, although EGS also occurs in several northern European countries and an identical condition called mal seco has been recognised in Argentina, the Falklands, Colombia and Chile.
