Atypical Myopathy

Atypical Myopathy:

Atypical Myopathy (AM) is a seasonal condition which occurs in horses at pasture. Ingestion of plant material containing the toxin hypoglycin A (HGA) results in non-exertional rhabdomyolysis. In Europe, seeds and seedlings from Acer pseudoplatanus (Sycamore) are the primary source of HGA. It is therefore no surprise that disease incidence peaks in the Autumn and Spring, resulting from ingestion of seeds and seedlings. Relatively more cases occur in Autumn and are attributed to ingestion of samaras. Samaras are winged fruits containing Acer seeds. During years when there are a high number of cases in Autumn, cases tend to be seen the following spring as seeds germinate and progress into seedlings.

Sycamore Poisoning: IEC Update – 10/10/22

The Irish Equine Centre has shared the following alert regarding sycamore poisoning:

There seems to be a significant seed crop on the sycamore trees this year and as far as we are aware there have been two cases recorded over the past few days. So if people have had cases before they need to be particularly careful and where the sycamore trees have a significant seed crop people need to be careful about exposure over the next few weeks. Wet and windy weather will bring down the seeds quicker. For further information please contact the Irish Equine Centre at:

Federation of European Equine Veterinary Associations (FEEVA) Board meeting in Brussels: Updated 7 March 2022

Last week, the FEEVA board had a physical meeting in Brussels after a long COVID break. One of the important topics that were discussed was the horrible war activities in Ukraine. The board decided to engage in horse health and welfare in the area, focusing not only on the horses in Ukraine but also on the horses transported across the borders. The board will keep FEEVA members informed of the actions and progress. To provide practical support, FVE, WVA, and FECAVA have developed a web portal to coordinate aid by veterinarians to help Ukrainian veterinarians, their families, and animals.

The portal puts together information on:

  • Pet travel rules and support to refugees fleeing with their animals;
  • Places to stay for Ukrainian veterinarians and their animals by country;
  • Diploma recognition of Ukrainian veterinarians;
  • Support initiatives for Ukrainian veterinary students;
  • Other veterinary support or money donations initiatives.

Please feel free to share this portal widely:


Rules of Racing – New Equine Influenza Vaccination Intervals

The IHRB have sent to correspondence to all licensed trainers and point to point handlers regarding changes to vaccination intervals under Rule 91 of the Rules of Racing and Irish National Hunt Steeplechase Rules. The IHRB are extending this communication to Veterinary Surgeons as they recognize that you are at the forefront of appropriate vaccination administration.

As you may well be aware, Rule 91 which concerns the time intervals for Equine Influenza vaccination came into effect in Ireland and Great Britain on 1st January 2022. This change was implemented in a bid to minimize the recognized waning in immunity between vaccinations.

UCD Research Project on PPID

Invitation to participate in PPID Study

Hypertrichosis is one of the most common clinical signs of pituitary pars intermedia dysfunction (PPID), also known as Equine Cushing’s disease, a condition that affects one in five horses over the age of 15. Researchers at University College Dublin in collaboration with researchers at the University of Kentucky’s Gluck Equine Research Centre are conducting a study to investigate the effects of blue light treatment in PPID horses over a 12-month period.

The team are recruiting interest from owners of PPID horses/ponies that meet a specific set of criteria to be part of this important study. If you own or manage a horse or pony diagnosed with PPID, and which displays hypertrichosis, please complete the following questionnaire. Both medicated (e.g. Pergolide) and unmedicated horses/ponies are suitable. Your participation in this study will help us to better understand PPID as a disorder of older horses, and in particular its impact on coat and coat condition.

Panorama Investigative programme:

The members of the IEVA were gravely concerned by the images shown in the recent Panorama investigative programme into slaughter of horses at an abattoir in the United Kingdom.

The working practices at this abattoir were appalling and should be formally investigated by the relevant authorities in regard to animal welfare and food standards. Michael Sheahan, Director of Veterinary Operations, DAFM confirmed that these practices do not occur in Irish abattoirs. While it is legal to transport horses to the UK for slaughter for human consumption, it is paramount that they are fit to travel and are presented with the correct passports ensuring food safety for consumers.

It is desirable that all horses lead a full life free from injury and stress, but inevitably there are a few that are unsuitable for re-homing once their career is finished. Euthanasia carried out humanely is a valid option. Some horses are excluded from the food chain due to the administration of certain medicines. Furthermore horse owners who wish that their horses never end up in abattoirs can proactively sign their passports out of the food chain.


FVE / FEEVA joint position  on ‘Best practice Protocol for Euthanasia of horses’:

When horses need to be euthanised there are several matters to consider. A method of euthanasia is only acceptable when its effect is guaranteed. It must cause loss of consciousness before cardiac or respiratory arrest. As well, human safety during euthanasia should be addressed because of the potential hazards and unpredictability of the procedure, and proper disposal of the carcass after euthanasia should be arranged and considered before selecting the method of euthanasia. Based on those matters, FVE and FEEVA built a joint technical document for the “Best practice Protocol for Euthanasia of horses”. The joint position was adopted by the FVE and the UEVP on 11 June 2021.

Contagious Equine Metritis

Contagious Equine Metritis (CEM) – Update:

DEFRA in the UK have announced that on the 9th of June 2021 a stallion at an equine premise in West Devon tested positive for Contagious Equine Metritis (CEM). Three mares which had close contact with the infected horse at the same premises are currently under investigation. The source of infection is believed to be contact with a stable mate abroad, before arriving in the UK.

Further information is available from the International Collating Centre (ICC). The affected horse a three year old Arab stallion, was imported to the UK in October 2020 from Europe and has had no clinical signs of infection. The diagnosis was made following targeted investigative testing after it came to light that another linked stallion on a premises in the Netherlands had tested positive for CEM on routine testing. The initial positive diagnosis was made by Axiom Veterinary Laboratories by PCR on penile swabs and this was confirmed on further samples tested at the Animal and Plant Health Agency (APHA) reference laboratory at Penrith by PCR on 8 June 2021; bacterial culture is pending at both laboratories.

The National Disease Control Centre of DAFM has indicated that there are no forward or backward tracing links to Ireland at this stage. DAFM will continue to monitor the situation closely. Compliance with the Code of Practice in relation to CEM prevention is particularly important at this time.

The ICC also reported two outbreaks of CEM in Icelandic horses in Germany this month, both confirmed by Labor Dr Bose GmbH.

Equine Herpesvirus Neurological Disease: Outbreak Update – 6th April 2021

Ann Cullinane MVB PhD 

Equine herpesviruses are endemic in horse populations worldwide and equine herpesvirus 1 (EHV1) respiratory disease and abortion are diagnosed each year in Ireland. EHV1 neurological disease is less common but when it occurs, often results in fatalities. Vaccination is a useful aid in the control of abortion and respiratory disease but no vaccine has an efficacy claim against the neurological form of the disease.

On the 20th of February the FEI were notified of a suspected outbreak of EHV1 neurological disease in showjumpers at the CES Valencia Spring Tour in Spain and reacted promptly to cancel the rest of the event.
