The number of cases of atypical myopathy is increasing. If you are aware of a case, the Atypical Myopathy Alert Group (AMAG) would like to invite you to report it to their researchers at the University of Liege, via the following link:

AUTUMN 2013 Update - As of the 29th November 2013, 310 clinical cases compatible with the diagnosis of atypical myopathy have been communicated to Liege University and to the RESPE.  These cases were recorded in Belgium (109 cases), France (81 cases), Great-Britain (40 cases), The Netherlands (22 cases), Switzerland (11 cases), Czech Republic (8 cases), Ireland (2 cases) and Germany (37 cases).

 

The seasonal climate conditions are those favourable to the emergence of cases of atypical myopathy. Today we know that the toxin responsible for the condition is present in the seeds of some Acer such as Acer pseudoplatanus (= maple tree; see (http://www.myopathieatypique.fr/en/etiologie/). Hence it is important to prevent horses from ingesting these seeds.

 

With temperature changes the seeds will begin to fall and the risk of poisoning increases.  If feasible, access to pastures where Acer can be found, must be limited.
