Other potential causes such as paralytic shellfish poisoning (PSP), neurotoxic shellfish poisoning (NSP), scombrotoxin fish poisoning, and pufferfish poisoning should be excluded. [ 1 ] The reversal of hot and cold sensations is an occasional symptom of CFP that may help differentiate it from norovirus .
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.
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.
PSP has been implicated as a possible cause of sea otter mortality and morbidity in Alaska, as one of its primary prey items, the butter clam (Saxidomus gigantea) bioaccumulates saxitoxin as a chemical defense mechanism. [11] In addition, ingestion of saxitoxin-containing mackerel has been implicated in the death of humpback whales. [12]
Vibrio vulnificus is the most common cause of death due to seafood in the United States, causing over 95% of deaths that are known to have occurred due to ingested seafood. If treatment with tetracycline or other cephalosporin antibiotics is initiated at the onset of symptoms and the full course followed, patients generally experience no long ...
The term fish kill, known also as fish die-off, refers to a localized mass die-off of fish populations which may also be associated with more generalized mortality of aquatic life. [ 1 ] [ 2 ] The most common cause is reduced oxygen in the water, which in turn may be due to factors such as drought , harmful algal bloom , overpopulation , or a ...
Amnesic shellfish poisoning (ASP) is an illness caused by consumption of shellfish that contain the marine biotoxin called domoic acid. [1] In mammals, including humans, domoic acid acts as a neurotoxin, causing permanent short-term memory loss, brain damage, and death in severe cases.
Edwardsiella tarda is a member of the family Hafniaceae. [1] [2] The bacterium is a facultatively anaerobic, small, motile, gram negative, straight rod with flagella.[1] [2] Infection causes Edwardsiella septicemia (also known as ES, edwardsiellosis, emphysematous putrefactive disease of catfish, fish gangrene, and red disease) in channel catfish, eels, and flounder.
