For most of us, food means nourishment, flavor, and comfort. But in many parts of the world, what’s on your plate could come with a deadly risk. Some of the most common ingredients can be dangerous—even fatal—if not handled properly. Yet, millions of people consume them every day.

Let’s take a closer look at ten of the world’s deadliest foods, the risks they pose, and why people still choose to eat them.

Cassava: The Cyanide-Laced Staple That Kills 200 Each Year

Cassava looks like an ordinary root vegetable, but hidden inside its roots and leaves are cyanogenic glycosides. When improperly prepared or eaten raw, these compounds release cyanide—a deadly toxin. According to the World Health Organization (WHO), cassava poisoning is responsible for about 200 deaths every year. It’s been dubbed the “world’s deadliest food.”

Despite its dangers, cassava is a crucial food source for more than 800 million people across 80 countries. It’s easy to grow, thrives in drought-prone areas, and is packed with carbohydrates. The risk comes when it isn’t processed correctly. Proper preparation—soaking, fermenting, drying, or boiling—removes the cyanide, making cassava safe to eat. For many communities, eating cassava isn’t a choice; it’s a necessity for survival.

Fugu: Japan’s Deadly Delicacy

In Japan, blowfish—known as fugu—is a prized delicacy. But eating it comes with a serious risk. The pufferfish contains tetrodotoxin, a poison said to be “200 times more deadly than cyanide,” according to the BBC. Tetrodotoxin poisoning works fast and brutally, starting with numbness around the mouth, leading to paralysis, and eventually death. What makes it worse? The victim remains conscious the entire time. And there’s no known antidote.

Each year, around 50 people—mostly unlicensed individuals or fishermen—are poisoned by fugu, and a few of those cases end in death. In Japan, only highly trained, licensed chefs are allowed to prepare fugu. They meticulously remove the toxic organs, including the liver, ovaries, and intestines. Still, many diners are drawn to the thrill of tasting this dangerous fish, with the slight tingling from residual toxins adding to its appeal.

Starfruit: A Sweet Fruit with a Hidden Danger

Starfruit might seem like a healthy snack, loaded with vitamin C and antioxidants, but it hides a deadly risk for people with kidney disease. This fruit contains neurotoxins that healthy kidneys can filter out without a problem. However, in those with kidney issues, these toxins accumulate and can trigger seizures, confusion, and, in severe cases, death.

For most people, starfruit is perfectly safe and even beneficial. But if you have kidney problems, it’s best to avoid this pretty, five-pointed fruit altogether.

Cherry Pits and Apple Seeds: Sweet Fruits, Toxic Centers

You probably don’t think twice about eating cherries or apples, but did you know their seeds and pits contain amygdalin? When chewed or crushed, amygdalin releases cyanide. Swallowing a whole cherry pit likely won’t harm you, but breaking it open and consuming the contents can be dangerous. In large amounts, the toxins can cause dizziness, nausea, and difficulty breathing—and even death in extreme cases.
