Isolated reports of scombroid food poisoning in humans caused by histamine present in the tissues of stale or rotten scombroid fish, usually tuna, have occurred over the years. In September 2016, authorities in Singapore intercepted canned tuna imported from Thailand after finding high levels of histamine. [12] No human cases were reported.
Domestic dogs may develop systemic toxemia after consuming C. botulinum type C exotoxin or spores within bird carcasses or other infected meat [103] but are generally resistant to the more severe effects of C. botulinum type C. Symptoms include flaccid muscle paralysis, which can lead to death due to cardiac and respiratory arrest.
These symptoms are due to vasoconstriction caused by maitotoxin. [6] [21] [22] [23] Ciguatoxin lowers the threshold for opening voltage-gated sodium channels in synapses of the nervous system. Opening a sodium channel causes depolarization, which could sequentially cause paralysis, heart contraction, and changing the senses of hot and cold.
Like humans and other animals, fish suffer from diseases and parasites.Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth.

Fish kills are often the first visible signs of environmental stress and are usually investigated as a matter of urgency by environmental agencies to determine the cause of the kill. Many fish species have a relatively low tolerance of variations in environmental conditions and their death is often a potent indicator of problems in their ...
In addition, ingestion of saxitoxin-containing mackerel has been implicated in the death of humpback whales. [12] Additional cases where PSP was suspected as the cause of death in Mediterranean monk seals (Monachus monachus) in the Mediterranean Sea [13] have been questioned due to lack of additional testing to rule out other causes of ...
