One bite can be fatal: Department of Health and Wellness urges public to avoid wild mushrooms

A walk through the garden or a family outing in the park could have devastating consequences this winter if wild mushrooms are picked and eaten. As the rainy season brings an abundance of mushrooms across the Western Cape, the Department of Health and Wellness is urging residents not to consume any wild mushrooms, warning that even a single bite of certain species can be fatal.

A dangerous spike in cases

The warning follows a concerning spike in confirmed cases of Death Cap mushroom poisoning in the province. Wild mushrooms are now commonly appearing in gardens, parks, vineyards and forests. Although some may look harmless or resemble edible varieties, experts warn that it is impossible to determine whether a mushroom is safe to eat based on appearance alone.

Know the danger: the Death Cap mushroom

One of the most dangerous species is the Death Cap mushroom (Amanita phalloides), one of the world’s most poisonous mushrooms. Eating even a small amount can lead to severe liver failure and death. Its toxins remain deadly even after the mushroom has been cooked, dried or frozen.

The Death Cap mushroom is typically identified by:

– A smooth olive-green to yellowish cap, although the colour may range from pale green to almost white.

– White gills beneath the cap.

– A white stem with a skirt-like ring.

– A cup-like sac (volva) at the base of the stem, often hidden beneath soil or leaf litter.

Symptoms and what to do

Symptoms usually develop between six and 24 hours after consumption and include severe vomiting, diarrhoea and abdominal pain. Many people appear to recover after the initial illness, but this can be misleading. Without urgent medical treatment poisoning can rapidly progress to liver failure, kidney injury and death.

Carine Marks, director of the Tygerberg Poisons Information Centre, said the recent spike in cases is deeply concerning.

“Historically, the National Poison Information Helpline has received only one or two confirmed Death Cap poisoning cases each year from across South Africa. Alarmingly, five confirmed cases have already been reported in the past two weeks, all from the Western Cape.”

She urged the public not to rely on appearance or common myths to determine whether a mushroom is safe to eat.

“There is no reliable home test to distinguish edible mushrooms from poisonous ones, and even experienced foragers can mistake a deadly mushroom for an edible variety. Our advice is simple: do not collect or eat wild mushrooms unless they have been positively identified as safe by a recognised mushroom expert.”

Marks stressed that time is critical if mushroom poisoning is suspected.

Do not wait for symptoms to develop. If someone has eaten a wild mushroom seek immediate medical attention, even if they appear well. Early treatment can save lives.

Children especially at risk

Dr Bradley Browne, director of the Red Cross Hospital Poisons Information Centre, said children are especially vulnerable because of their natural curiosity.

“Children often explore their surroundings by touching or tasting objects they find outdoors. A mushroom growing in a garden or park may seem harmless, but it can have life-threatening consequences. We urge parents and caregivers to inspect areas where children play and remove wild mushrooms where possible.”

Browne said preventing exposure is the most effective way to protect children.

“Never eat mushrooms picked from the wild, and seek immediate medical care if accidental ingestion is suspected.”

When in doubt throw it out

The Department of Health and Wellness reminds the public and health-care professionals that the National Poison Information Helpline is available to provide urgent advice in cases of suspected poisoning.

In case of accidental ingestion or exposure seek medical care at your nearest clinic immediately, or contact the Poison Information Helpline of the Western Cape (PIHWC) at 086 155 5777.
