Shellfish poisoning
A type of noninfectious foodborne contamination as a result of the intake of specific forms of
contaminated fish and shellfish
Severity of symptoms relies upon of what toxin is affected, need to are searching for medical
interest right now, extreme cases may be deadly, can be contaminated at some point of or after
algae blooms
○ Include mussels, oysters, clams, scallops, cockles, abalone, whelks, moon snails, Dungeness
crab, shrimp and lobsters
Shellfish poisoning S&S/Prevention
Usually 30-60 minutes after consuming contaminated shellfish; Numbness and tingling, HA,
Nausea, Vomiting, Diarrhea, Confusion
Avoid shellfish in low earnings u . S . Or uncertain of the water satisfactory or in areas that lately
had an algae bloom otherwise called "crimson tide" or "brown tide"
Ciguatera poisoning
A condition because of marine pollution produced by using dinoflagellates (microscopic sea
organisms)
-Eating fish that's been infected by way of pollution determined by way of tiny algae located
around coral reefs; toxin does no longer modify appearance, flavor or scent. It is likewise not
destroyed after cooking
○ Fish usually affected: Barracuda, moray eel, grouper, amberjack, sea bass, sturgeon, parrot
fish, surgeonfish, and pink snapper
Ciguatera poisoning S&S
○ Usually develop after 3-6 hours however occasionally after 30 hours, Nausea, vomiting,
diarrhea, stomach ache, tingling, enamel ache or feeling as if tooth are free, itching, steel flavor
inside the mouth, blurred imaginative and prescient, extended sensitivity to warm and cold
○ Prevention: Avoid or limit ingesting sparkling reef fish, particularly the liver, intestines, eggs or

, ○ Note: Symptoms normally final a few days however can have lingering consequences for
months. Symptomatic remedy. Patients commonly must avoid fish, nuts, alcohol and caffeine for
6 months to save you signs from returning.
Scombroid poisoning
-Caused by intake of dark-meat fish (e.G., bonito, mackerel, mahi-mahi, tuna) improperly stored
at warmth.
-Bacterial histidine decarboxylase converts histidine to histamine. Histamine isn't always
degraded by means of cooking.
Symptoms
Acute-onset burning sensation of the mouth, flushing of face, erythema, urticaria, palpitations,
blurred vision, cramps, diarrhea, pruritus, headache. May motive anaphylaxis-like presentation
(i.E., bronchospasm, angioedema, hypotension).
-Frequently misdiagnosed as allergy to fish.
-Treat supportively with antihistamines; if needed, antianaphylaxis (e.G., bronchodilators,
epinephrine).
Foodborne illness
Illness because of the intake of meals or water infected with micro organism and/or their
pollution, or with parasites, viruses, or chemical substances
A meals-borne disease outbreak is described with the aid of the subsequent 2 standards:
- Similar contamination, often GI, in a minimum of 2 people
- Evidence of meals as the source
Foodborne infection S&S
Varying in diploma and combination
Include stomach ache, vomiting, diarrhea, and headache; greater severe instances can result in
life-threatening neurologic, hepatic, and renal syndromes main to permanent disability or loss of
life
Foodborne infection Treatment
