Buying Horse Hay in South Africa: What Should You Check for Senecio?
By the SportHorses.co.za editorial team
When buying horse hay in South Africa, ask where it was grown, inspect opened bales and agree how suspect material will be handled before you accept a delivery. Do not assume a familiar supplier or a tidy-looking bale settles the question. Parys Animal Hospital’s undated guidance warns that poisonous plants can arrive in hay from other parts of the country, including plants uncommon near your yard. Read its Senecio guidance.
The practical distinction is between checking a paddock you know and accepting forage from land you have never seen. A useful buying routine connects the supplier, the delivery and the person filling the hay nets. This is a guide to that conversation, not a method for diagnosing poisoning or identifying every toxic plant.
Why should South African horse owners ask about Senecio?
Senecio deserves a specific question because local veterinary guidance identifies both pasture and hay as possible routes of exposure. Parys Animal Hospital’s undated article describes liver damage from these plants and names Senecio retrorsus mainly in winter-rainfall areas and Senecio latifolius in summer-rainfall areas. Ask your vet to confirm the risks relevant to the source of your forage rather than treating these broad descriptions as a complete distribution map. Parys Animal Hospital.
This is not a newly discovered issue. A review by C.J. Botha and T.W. Naude, published in the Journal of the South African Veterinary Association in 2002, includes seneciosis, also called “dunsiekte”, among plant poisonings of horses in southern Africa. Its accessible abstract establishes that regional context; it does not provide a bale-inspection protocol or evidence of today’s incidence. Read the review abstract.
For a buyer, the useful response is not to memorise a list of Latin names. It is to make the origin and condition of forage part of the purchase conversation. Ask who can help identify unfamiliar plant material before it becomes a disagreement about whether the hay is acceptable.
Buy the forage with a checking routine, not just a delivery arrangement.
What should you ask a hay supplier before delivery?
Ask about the growing area, the particular consignment and the process for reporting suspect material. These are proposed purchasing checks, not statutory requirements or a guarantee of safe forage. Put the answers somewhere the yard manager can find them.
| Buying question | Useful detail to request | What it does not establish |
|---|---|---|
| Where was this hay grown? | The growing area and whether the load has more than one source | That the hay is free of poisonous plants |
| Can I inspect opened bales? | An opportunity to examine material beyond the outside of a bale | That every bale is identical |
| How do you handle a suspect delivery? | A named contact and an agreed reporting process | An automatic right to a refund |
| Can we identify this consignment later? | A delivery reference and source details | A laboratory assessment of its contents |
A supplier who can discuss these points gives you something concrete to work with. If an answer is unavailable, record that uncertainty rather than filling the gap with an assumption. You can then decide whether to seek further advice or another source.
Make the acceptance arrangement explicit before unloading: who checks the hay, where it will be stored pending inspection and who can authorise feeding it. For a livery client, this is a useful discussion with the yard manager even when the client does not buy forage directly.
How should a yard check hay without pretending to certify it?
Use a repeatable inspection routine, while recognising that a visual check is not a safety certificate. In its article dated January 14, 2016, HQ Magazine advises checking hay for weeds and other foreign material, loosening and shaking it out before feeding, and teaching grooms to put questionable material aside. Treat this as older practical guidance, not a current regulatory standard. HQ Magazine’s hay-safety advice.
A suggested yard workflow is:
- Record the supplier, delivery reference and growing area if supplied.
- Open bales for inspection rather than judging only their outer surfaces.
- Ask staff to flag unfamiliar plant material instead of guessing its identity.
- Keep suspect material separate from forage approved for feeding.
- Photograph the material and its delivery details for the supplier and your vet.
- Agree who decides what happens next, including whether further identification is needed.
Do not turn the checklist into a claim that a sampled load has been proven safe. Its purpose is to make concerns visible and traceable. Nor should a photograph from an article become your sole identification tool: ask a suitably qualified professional to assess material you cannot confidently identify.
For a prospective livery client, ask to see how the routine works in practice. Who opens the bales? Who receives a groom’s concern when the manager is away? The answer should be a workable handover, not simply “we use good hay”.
What is verified, and what still needs professional judgement?
The sources support concern about Senecio exposure, but they cannot tell you whether a particular bale or horse is affected. Parys Animal Hospital’s undated guidance lists signs including yellow gums, dullness, weight loss, colic signs and uncoordinated movement, and advises calling the vet as soon as possible when a horse shows a combination of the described signs. It also warns that toxic effects are not always reversible. Parys Animal Hospital.
Do not use that list to diagnose the cause yourself. If you suspect exposure or illness, contact your vet promptly and explain what was fed, which horses received it and what you have observed. Keep the conversation factual; an unfamiliar plant fragment is something to investigate, not proof of poisoning.
For someone buying a horse, forage records can help frame questions about its management, but they do not establish its health status. Keep this separate from the welfare and medication conversation before purchase. Both belong in a careful assessment; neither replaces veterinary advice.
What do buyers most often ask about hay checks?
Does locally bought hay necessarily come from local land?
Do not assume so. Parys Animal Hospital’s undated guidance specifically notes that hay can come from other parts of the country and bring plants uncommon in the receiving area. Ask where the particular consignment was grown. Parys Animal Hospital.
Can I identify Senecio from a yellow flower alone?
Do not make a feeding decision on that basis. Seek professional identification of suspect material rather than relying on one visual feature or an internet photograph.
Should grooms be involved in the checking routine?
Yes: make their reporting role explicit and ensure someone responds to concerns. HQ Magazine’s January 14, 2016 article specifically recommends teaching grooms to check hay and put questionable material aside. HQ Magazine.
Does a forage checklist replace a veterinary examination?
No. It is a management and purchasing aid, not a clinical assessment or a guarantee about a horse’s past exposure.
A sensible next step is to add forage sourcing and checking to your yard-viewing notes. For related ownership decisions, explore our South African horse-management guides and build a shortlist around the care you can verify, not assurances you cannot test.
