Over 200 People Are Killed by the “World’s Deadliest Food” Every Year — Yet Nearly 500 Million Still Eat It

It may sound shocking, but one of the most widely consumed foods on Earth is also considered the world’s deadliest. Every year, more than 200 people die from poisoning linked to this staple food — and yet nearly half a billion people continue to eat it daily.

That food is cassava.

What Is Cassava?

Cassava is a root vegetable grown mainly in:

• Africa

• South America

• Southeast Asia

It is a crucial source of calories for millions because it is:

• Cheap

• Easy to grow

• Resistant to drought

For many families, cassava is a matter of survival.

Why Is Cassava So Dangerous?

Cassava naturally contains cyanogenic glycosides, chemicals that can release cyanide — a deadly poison — when the plant is eaten improperly.

There are two main types:

• Sweet cassava (lower toxin levels)

• Bitter cassava (much higher toxin levels)

If cassava is not processed correctly, it can cause acute cyanide poisoning, which may be fatal.

How People Die From It

Deaths usually occur when:

• Cassava is eaten raw or undercooked

• Traditional processing steps are skipped

• Food shortages force people to rush preparation

Symptoms of poisoning include:

• Dizziness

• Vomiting

• Severe stomach pain

• Difficulty breathing

• Loss of consciousness

• Death in severe cases

Children are especially vulnerable.
