Iron poisoning can occur when doses of 20 to 60 mg/kg or more of elemental iron is ingested with most cases reporting primarily gastrointestinal symptoms. [4] Systemic signs and symptoms shown in serious toxicity occur at higher doses exceeding 60 mg/kg. [ 5 ]
The experiment included raising over 5,000 fish between the years 2001–2004, and analyzing the toxicity of muscle, skin, gonads, livers, and other organs. The team concluded that the amount of tetrodotoxin in all those parts was non-toxic, and it would allow for the safe preparation of fugu-kimo (puffer liver). [ 63 ]
Zinc toxicity has been seen to occur at ingestion of greater than 225 mg of zinc. [18] Excessive absorption of zinc can suppress copper and iron absorption. The free zinc ion in solution is highly toxic to bacteria, plants, invertebrates, and even vertebrate fish. [19] [20] [21]
Fish acute toxicity syndrome (FATS) is a set of common chemical and functional responses in fish resulting from a short-term, acute exposure to a lethal concentration of a toxicant, a chemical or material that can produce an unfavorable effect in a living organism. [1]

Aquatic toxicology is the study of the effects of manufactured chemicals and other anthropogenic and natural materials and activities on aquatic organisms at various levels of organization, from subcellular through individual organisms to communities and ecosystems.

Fish toxins or fish stupefying plants have historically been used by many hunter gatherer cultures to stun fish, so they become easy to collect by hand. Some of these toxins paralyse fish, which can then be easily collected. [ 1 ]

Animal livers are rich in iron, copper, B vitamins and preformed vitamin A.Daily consumption of liver can be harmful; for instance, vitamin A toxicity has been proven to cause medical issues to babies born of pregnant mothers who consumed too much vitamin A. [3] For the same reason, consuming the livers of some species like polar bears, dogs, or moose is unsafe.
