Certain foods around the world are renowned for their danger due to toxicity, difficulty in preparation, or potential for foodborne illness. Here are some of the most dangerous foods:
Fugu (Pufferfish): Fugu contains tetrodotoxin, a potent nerve toxin. Only licensed chefs are allowed to prepare it, and improper preparation can result in poisoning or death.

Ackee: The fruit is safe to eat only when fully ripened and cooked; unripe ackee contains hypoglycin A, which can induce severe vomiting and even fatal hypoglycemia.

Castor Beans: The seeds of the castor oil plant contain ricin, one of the most potent toxins known. Even small amounts can be lethal if ingested.

Elderberries: Raw elderberries, seeds, and other parts of the plant contain cyanogenic glycosides, which can produce cyanide when metabolized.

Sannakji: This dish features live octopus, which can pose a choking hazard due to the tentacles' ability to move and cling. If not chewed thoroughly, it can lead to suffocation.

Surströmming: This fermented herring emits strong odors and can harbor harmful bacteria if not properly stored. Consumption can lead to gastrointestinal distress.

Raw Cashews: Raw cashews contain urushiol, a toxic compound also found in poison ivy. Properly processed cashews are safe to eat.

Uncooked Flour: Raw flour can contain harmful bacteria like E. coli. Consuming it uncooked poses a risk of foodborne illness.

Red Kidney Beans: Raw or undercooked kidney beans contain high levels of phytohemagglutinin, which can cause severe nausea and vomiting.

Clams and Oysters: Consuming raw or undercooked shellfish can lead to Vibrio infections, which can cause severe illness or death, especially in vulnerable populations.
