⚠️Equine consumption of Ragwort causes irreversible, cumulative liver damage. ⚠️ I have worked with horses who had to be euthanised due to ragwort ingestion. ⚠️
Common Misrepresentations by eco/conservation groups on ragwort
“Ragwort is only mildly poisonous / not a serious risk to horses”
Some groups describe it as “mildly poisonous” and say horses avoid it due to bitterness.
Reality: It contains potent pyrrolizidine alkaloids causing irreversible, cumulative liver damage. Horses can eat it (especially wilted/dried in hay), and poisoning is a recognised issue in equine veterinary practice. Symptoms often appear late, after significant damage.
I have worked with rescue horses who have been euthanised due to organ damage resulting from grazing on poor pasture containing ragwort. These horses started to eat this plant when no other food was available and developed a taste for it. Over months they ate this plant and were poisoned over time.
Ragwort cannot be tolerated on grazing land for horses or cattle and should never be present in hay, haylage or silage.
Equestrians do not want blanket eradication, but will rightly become frustrated if neighbouring land results in reseeding of cleared land.
⚠️Be safe - control ragwort - protect your horses.⚠️
🌼 Ragwort misinformation is doing the rounds again — and it needs challenging.
Horse owners are not demanding that every ragwort plant be eradicated. They are asking for responsible, targeted control where it could spread into grazing land, hay fields or forage.
Fresh ragwort may often be avoided, but the risk changes when the plant is wilted, dried or hidden in hay. Its toxins remain active and can cause cumulative, irreversible liver damage, with symptoms sometimes appearing only when it is too late. 🐴
🌍Ragwort has ecological value, particularly for the Cinnabar moth and other invertebrates, but conservation and animal welfare should not be presented as opposing choices.
🔎So, what does the evidence actually say, and which familiar claims seriously misrepresent the risk?
