If you’re looking for the details behind this headline, it is most likely referring to cassava (manioc/yuca).
Cassava is a staple food for hundreds of millions of people, particularly in Africa, Asia, and Latin America. The plant can contain cyanogenic compounds, which can release hydrogen cyanide if cassava is improperly processed. Severe poisoning can cause neurological symptoms and, in extreme cases, death.
However, the headline needs some caution:
- “World’s deadliest food” is a sensational label, not a scientific classification.
- Nearly 500 million people consuming cassava is a commonly cited estimate, although the exact number varies by source and definition.
- Claims that “over 200 people are killed every year” are difficult to establish as a precise global figure because cassava-related poisoning is underreported in many regions.
- Proper processing—such as peeling, soaking, fermenting, drying, and/or thoroughly cooking, depending on the cassava variety and traditional method—substantially reduces the cyanogenic compounds.
- Bitter cassava generally contains more cyanogenic compounds than sweet varieties and requires particularly careful processing.
So the key point isn’t that cassava is inherently deadly. Properly processed cassava is an important food for hundreds of millions of people; the danger comes primarily from consuming inadequately processed varieties containing high levels of cyanogenic compounds.
If you want, I can also give you a detailed, fact-checked article explaining the “200 deaths / 500 million people” claim and where those numbers come from.
