The death cap and wild mushroom safety in South Africa
If anyone eats a wild mushroom, go to hospital at once, even if they feel fine. Do not wait for symptoms. This matters most with the death cap, whose symptoms are delayed by hours and whose victims may seem to recover before the liver fails.
The death cap
Many wild mushrooms grow in South Africa after rain. Some are edible, many are harmless but inedible, and some are deadly. The most dangerous is the death cap (Amanita phalloides).
- It grows on the ground under oak, pine and poplar trees, in parks, forests and gardens, especially in the Western Cape.
- It can look like an ordinary mushroom: pale greenish, yellowish or white, with white gills and a ring on the stem.
- Its poison destroys the liver and kidneys.
- The poison is not destroyed by cooking, drying or freezing.
Why it is so dangerous
Vomiting, severe diarrhoea and stomach pain usually start 6 to 24 hours after eating. The symptoms may then seem to settle for a day or two, while the liver is being damaged. Treatment is in hospital, often in intensive care, and some patients need a liver transplant.
Early hospital treatment can save a life. Waiting to see whether symptoms appear can cost it.
In July 2026, Western Cape health officials warned residents not to pick or eat wild mushrooms after five confirmed death cap cases in two weeks, many more than the one or two a year usually recorded.
There is no home test
None of these tells you that a wild mushroom is safe:
- a silver spoon that does not turn black;
- a cap that peels;
- animals or insects eating it;
- its colour or smell.
The rule for every family is simple: never eat a wild mushroom.
If someone eats a wild mushroom
- Go to the nearest hospital or emergency unit immediately, even if the person feels well.
- Phone the Poisons Information Helpline on 0861 555 777, which answers 24 hours a day, for advice on the way.
- Take the rest of the mushroom with you, wrapped in paper and not plastic, or a clear photograph that shows the gills and the base of the stem.
Keep the helpline number where everyone in the home can see it.
Children and pets
Small children put things in their mouths. After rain, check the lawn and the ground under trees where children play, and remove any mushrooms that have come up. If a child may have eaten one, treat it as an emergency in exactly the same way.
Grow your own safely
Growing mushrooms at home from bought spawn is the safe way to enjoy them. Even so:
- If a mushroom you did not plant comes up in or near your growing bags, do not eat it. It may be a wild mushroom whose spores blew in.
- Eat only what you grew from spawn that you bought and can identify.
- Grow in a ventilated space, away from bedrooms and living rooms. Mushroom spores and mould can irritate the lungs.
In short
- Never eat a wild mushroom.
- No home test works.
- Cooking does not make a death cap safe.
- Go to hospital at once, without waiting for symptoms.
