ICD-10: T61.14

Scombroid fish poisoning is a type of foodborne illness caused by the consumption of spoiled fish, particularly those belonging to the Scombridae family, such as tuna and mackerel. The diagnosis of scombroid fish poisoning, specifically under the ICD-10-CM code T61.14, involves several criteria that healthcare professionals utilize to identify the condition accurately.

Diagnostic Criteria for Scombroid Fish Poisoning

1. Clinical Presentation

• Symptoms: Patients typically present with acute onset of symptoms, which may include flushing, rash, headache, abdominal cramps, diarrhea, and palpitations. These symptoms usually occur within minutes to a few hours after consuming the affected fish[1].
• Duration: Symptoms are generally self-limiting, lasting from a few hours to a couple of days, which is a key characteristic of scombroid poisoning[1].

2. History of Fish Consumption

• Recent Intake: A critical factor in diagnosing scombroid fish poisoning is a recent history of consuming fish known to be susceptible to spoilage, particularly if the fish was improperly stored or handled[1].
• Type of Fish: Identification of the specific type of fish consumed can aid in diagnosis, as scombroid poisoning is primarily associated with certain species like tuna, mackerel, and bonito[1].

3. Exclusion of Other Conditions

• Differential Diagnosis: It is essential to rule out other potential causes of the symptoms, such as allergic reactions, other types of food poisoning, or infections. This may involve laboratory tests or patient history to confirm that the symptoms are not due to other etiologies[1].
• Laboratory Testing: While specific laboratory tests for scombroid poisoning are not routinely performed, testing for histamine levels in the fish or blood may be conducted in some cases to support the diagnosis[1].

4. Epidemiological Context

• Outbreaks: Awareness of any recent outbreaks of scombroid poisoning in the community or among individuals who consumed the same fish can also support the diagnosis. Public health reports or advisories may provide relevant information[1].

5. Response to Treatment

• Symptomatic Relief: The response to treatment, such as antihistamines, can also provide insight into the diagnosis. Patients often experience rapid improvement with appropriate symptomatic treatment, which is indicative of scombroid poisoning[1].

Conclusion

In summary, the diagnosis of scombroid fish poisoning (ICD-10 code T61.14) relies on a combination of clinical symptoms, history of fish consumption, exclusion of other conditions, and epidemiological context. Healthcare providers must consider these criteria to ensure accurate diagnosis and appropriate management of the condition.

Scombroid fish poisoning is a type of foodborne illness that occurs due to the consumption of improperly stored or handled fish, particularly those belonging to the Scombridae family, such as tuna and mackerel. The condition is characterized by the presence of high levels of histamine, which can develop when fish are not refrigerated adequately after being caught. This histamine can cause a range of symptoms that mimic allergic reactions.

Clinical Description of Scombroid Fish Poisoning

Etiology

Scombroid fish poisoning is primarily caused by the accumulation of histamine in fish flesh due to bacterial action on the amino acid histidine, which is abundant in certain fish species. When fish are not kept at appropriate temperatures, bacteria convert histidine into histamine, leading to toxic levels that can cause illness upon consumption[1][2].

Symptoms

The symptoms of scombroid fish poisoning typically appear within minutes to a few hours after eating contaminated fish. Common symptoms include:

• Flushing of the face and neck: This is often one of the first signs and can resemble an allergic reaction.
• Headache: Patients may experience significant discomfort.
• Nausea and vomiting: Gastrointestinal symptoms are common and can lead to dehydration.
• Abdominal cramps: These may accompany nausea and vomiting.
• Diarrhea: Some individuals may experience diarrhea as part of the gastrointestinal response.
• Rash or hives: Skin reactions can occur, further mimicking allergic responses.

In severe cases, symptoms can escalate to include difficulty breathing, palpitations, and hypotension, although these are less common[3][4].

Diagnosis

The diagnosis of scombroid fish poisoning is primarily clinical, based on the history of fish consumption and the presentation of symptoms. Laboratory tests are not typically required but may be used to rule out other conditions. The ICD-10 code for this condition is T61.14, which specifically denotes scombroid fish poisoning as "undetermined," indicating that the specific circumstances of the poisoning (e.g., accidental or intentional) are not specified[5][6].

Treatment

Treatment for scombroid fish poisoning is generally supportive. Antihistamines may be administered to alleviate symptoms, particularly if there is significant flushing or rash. In most cases, the symptoms resolve within a few hours to a couple of days without the need for extensive medical intervention. Hydration is also important, especially if vomiting or diarrhea occurs[7].

Prevention

Preventing scombroid fish poisoning involves proper handling and storage of fish. Key preventive measures include:

• Immediate refrigeration: Fish should be kept at temperatures below 4°C (39°F) as soon as possible after being caught.
• Proper cooking: While cooking does not eliminate histamine, it can help reduce the risk of other foodborne illnesses.
• Awareness of fish sources: Consumers should be cautious about purchasing fish from unreliable sources that may not adhere to safe handling practices[8].

Conclusion

Scombroid fish poisoning, classified under ICD-10 code T61.14, is a significant public health concern related to the consumption of improperly stored fish. Understanding its clinical presentation, symptoms, and preventive measures is crucial for both healthcare providers and consumers to mitigate the risks associated with this foodborne illness.
