Two days ago, a tragic incident in Vizhinjam, Thiruvananthapuram, shocked Kerala. Two individuals reportedly lost their lives following suspected seafood-related illness. While official investigations are still underway to determine the exact cause — whether it was food poisoning, allergic reaction, or another complication — the incident has raised serious concerns about seafood safety and awareness.

This is not about creating fear.
It is about understanding science, recognising symptoms early, and knowing when to seek help.

Seafood is a rich source of protein, omega-3 fatty acids, iodine and essential minerals. For many, it is a healthy and delicious choice.

But for some individuals, seafood can trigger serious reactions — ranging from mild stomach upset to life-threatening emergencies.

Understanding the difference between seafood allergy and seafood poisoning can save lives.

What Foods Commonly Cause Reactions?

Seafood-related reactions are most commonly triggered by:

Crustaceans (Most Common)

• Shrimp
• Crab
• Lobster

These are the leading causes of seafood allergy, especially in adults.

Molluscs

• Mussels
• Clams
• Oysters

Fish

Fish allergy is comparatively less common than shellfish allergy but can still cause significant reactions.Seafood allergy is more common in adults than in children.

Recognising the Symptoms

Symptoms may involve different body systems. They usually appear within 30 to 120 minutes after consumption.

1. Abdominal Symptoms

• Colicky abdominal cramps
• Nausea
• Vomiting
• Diarrhoea

2. Skin Symptoms

• Redness
• Itching
• Hives
• Swelling of lips, eyelids or face

3. Chest & Breathing Symptoms

• Cough
• Breathlessness
• Wheezing

4. Severe Warning Signs

• Dizziness
• Fainting
• Sudden fall in blood pressure

When multiple systems are involved — especially breathing difficulty and low BP — it may indicate anaphylaxis, a medical emergency.

How to Identify Seafood Allergy

If allergic symptoms:

• Occur within 30–120 minutes after eating shellfish or fish
• And happen repeatedly whenever that food is consumed

It should be regarded as a probable food allergy.

Unlike simple food intolerance, true allergy involves the immune system and can worsen with repeated exposure.

What Should You Do?

Consult an Expert

Meet a qualified doctor and discuss your symptoms in detail.

Get Tested

Doctors may recommend:

• Skin prick tests
• Blood tests (IgE testing)

Take Preventive Precautions

• Read food labels carefully
• Avoid known allergenic foods
• Be cautious while eating out
• Inform restaurants about your allergy
• Carry emergency medication if prescribed
• Reach a medical facility immediately if symptoms appear

When to Rush to Hospital

Seek immediate medical help if you experience:

• Difficulty breathing
• Throat tightness
• Persistent vomiting
• Severe dizziness
• Collapse or fainting

Delaying treatment can be dangerous.

The Vizhinjam tragedy reminds us that awareness is not optional — it is essential.

Seafood is nutritious — but safety, proper storage, and allergy awareness matter.
