If you were to find yourself wandering through the lush forests of New Zealand, chances are you might come across some strange looking berries hanging from a tree. Known as karaka berries, these distinctive fruits are found all over the country and have been treasured by the indigenous Māori people for centuries. However, what you may not know is that these berries come with a dangerous secret. Are karaka berries poisonous to humans? The answer is a resounding yes. Let’s take a closer look at this mysterious fruit.
What is it about karaka berries that makes them so dangerous? Well, for starters, they contain a toxic alkaloid called karakin. This potent poison can cause a range of unpleasant symptoms in humans, from vomiting and diarrhea to seizures and respiratory failure. The effects of karakin can be lethal if eaten in large enough quantities, which is why it’s so important to avoid eating these berries unless you’re a skilled forager with extensive knowledge about which ones are safe to consume.
Despite the risks, karaka berries still hold a special place in Māori culture. They are the subject of many myths and legends, and are used in traditional medicines and rituals. However, their toxicity is not to be taken lightly and it’s important to exercise caution when exploring the New Zealand wilderness. So, are karaka berries poisonous to humans? Absolutely. But with the right knowledge and respect, we can better appreciate the beauty and complexity of this ancient fruit.
Toxicity of Karaka Berries
Karaka berries are the fruits of the karaka tree, which is native to New Zealand. While these berries have been used for centuries by the indigenous Maori people for food and medicine, they are known to be toxic to humans when ingested improperly.
The toxicity of karaka berries lies in the presence of a toxic alkaloid called karakin. This compound is primarily found in the kernel of the berry, which is the hard, bitter, nut-like structure that surrounds the seed. Karakin is a potent toxin and can cause serious harm or death if consumed in large amounts.
- Symptoms of karaka berry poisoning can include severe vomiting, diarrhea, abdominal pain, weakness, tremors, convulsions, and even respiratory failure.
- The severity of symptoms depends on the amount of karakin ingested and the individual’s sensitivity to the toxin.
- Children are particularly susceptible to karaka berry poisoning and should never be allowed to handle or ingest these berries. Pets are also at risk if they eat karaka berries.
The Maori people traditionally used a lengthy process to remove the toxic alkaloid from the kernels before consuming them, but this process is not recommended for amateurs. The best course of action is to avoid eating karaka berries altogether.
Although karaka berries are not commonly available in supermarkets or grocery stores, they are sometimes used as ornamental plants in gardens or public spaces. It is essential to recognize the tree and its fruit and take precautions not to ingest the berries, especially if you have small children or pets.

In conclusion, while karaka berries have been used for centuries as a food and medicine by the Maori people, they are toxic to humans when consumed improperly. The presence of karakin in the kernels of the berry can cause severe symptoms and even death. It is essential to avoid eating these berries and to take precautions to prevent children and pets from ingesting them as well.
