T61.78
Other shellfish poisoning
Clinical Classification Guidelines
Medical Intelligence & Overview
Other shellfish poisoning, classified under ICD-10 code T61.78, refers to illnesses caused by consuming contaminated shellfish that contain toxins other than those associated with more common shellfish poisoning types like paralytic or neurotoxic shellfish poisoning. These toxins can lead to varying health symptoms and require appropriate medical attention. While these cases are less frequent, awareness of potential sources and symptoms is important to prevent complications.
Causes & Symptoms
Clinical Causes: Consumption of contaminated shellfish from waters polluted with marine toxins Eating shellfish exposed to harmful algal blooms that produce non-specific toxins Poor handling or storage of shellfish leading to toxin accumulation Ingestion of shellfish from unsafe harvesting areas not regulated or tested for toxins
Key Symptoms: Gastrointestinal discomfort: nausea, vomiting, diarrhea Abdominal pain and cramping Headache and dizziness Muscle weakness or numbness Taste disturbances or metallic taste in the mouth In some cases, neurological symptoms such as confusion or vision problems
Diagnostic & Treatment
Diagnosis Path: Diagnosis of other shellfish poisoning is primarily based on recent food intake history, particularly consuming shellfish from uncertain or unregulated sources. Healthcare providers may perform stool tests to identify toxins or bacterial pathogens if detectable. In some cases, identification of symptoms consistent with shellfish poisoning, combined with known exposure, guides the diagnosis. Laboratory analysis of leftover shellfish or water sources may be conducted when possible.
Treatment Protocols: Treatment focuses on alleviating symptoms and preventing dehydration. Supportive care may include fluids to manage dehydration caused by diarrhea and vomiting. In severe cases or if neurological symptoms develop, hospitalization may be necessary to monitor and provide advanced treatment. Importantly, there is no specific antidote for shellfish toxins, so prevention through safe sourcing and proper cooking practices is essential. Patients are advised to avoid further shellfish consumption until healthcare providers confirm recovery and safety.
