Mushrooms; Not every mushroom is created equal. Crimini mushrooms might make perfect pasta toppers, but some species contain poisons that can kill.

Tomatoes; The juicy, red fruit contains a poison, Glycoalkaloid, in its leaves, which is known for causing upset stomachs, severe cramping, and anxiety. So steer clear of the leaves and stems.

Rhubarb Leaves; Rhubarb might bake up all kinds of delicious sweets, but the leaves are poisonous, causing breathing trouble, seizures, kidney failure, and in some cases, death.

Peanuts; One of the most common allergies is to peanuts. The most severe response is anaphylaxis, which can lead to severe constriction of the airways, shock, and even loss of consciousness. It is dangerous enough to cause death if left untreated

Shellfish; A severe allergic reaction to shellfish can inhibit breathing and even be life-threatening.

Potatoes; Potatoes have both poisonous stems and leaves, but even so, potato poisoning is rare. Most potato-related deaths come from eating green potatoes, or drinking potato leaf tea.

Cherries; Watch out for cherry seeds, which contain poisonous hydrogen cyanide.

Raw Meat and Uncooked Eggs; They can contain salmonella bacteria, which can cause gastroenteritis in humans. Salmonella poisoning can also lead to serious complications, such as bacteremia that are life-threatening to people with weaker immune systems.

Almonds Bitter almonds, while in their raw form, are full of cynaide. They need to go through a specialized heat treatment (more than just your DIY oven roasting) in order to remove the toxins.

Hot Dogs; The ballpark favorite is the leading cause of choking fatalities among children, so watch your little ones when they scarf'em down.
