4)Giant Bullfrog
Giant bullfrog is considered a delicacy in Namibia. The Namibians eat the entire giant bullfrog except for the internal organs. In most cultures, only certain body parts of the frogs such as the legs are consumed as most frogs have poisonous skin and poisonous internal organs. A premature bullfrog is said to contain a certain toxin which could lead to kidney failure in most cases.
5)Ackee Fruit
The fruit looks like a pear, red in color when it's ripe. The ackee fruit must be picked after it has naturally opened and revealed the seeds. The fruit must be eaten at the right time. The fruit is poisonous if it is both immature and overripe. The fleshy part around the seeds is the only part which is edible. The rest of the fruit contain a type of toxin called hypoglycin which can be fatal if consumed.
6)Silver-Stripe Blaasop
The silver-stripe blaasop is a delicacy among the locals who live in some parts of the Indian Ocean.The locals are experts in removing the toxic parts of the fish before cooking and consuming it. The poison is concentrated in the liver,reproductive organs and also the skin of the fish which can cause paralysis and breathing problems if consumed by humans.
7)Echizen Jellyfish
The giant Echizen jellyfish is a huge, poisonous jellyfish which moves in swarms in the Japan waters. The jellyfish lives on tuna fish and this poses a problem as the tuna supply is affected by the huge consumption.

The toxic parts must be removed and the jellyfish must be properly cooked for safe consumption.
