Traveling is a wonderful way to explore the world and experience new cultures. However, it’s essential to stay healthy during your adventures. One common health issue travelers can encounter is food poisoning from seafood. In this article, we’ll cover various types of seafood-related illnesses and offer tips on how to prevent them. So, let’s dive in!
Shellfish Poisoning: Know the Risks and Symptoms
Shellfish poisoning is caused by toxins found in contaminated shellfish, such as mussels, oysters, clams, scallops, cockles, abalone, whelks, moon snails, Dungeness crab, shrimp, and lobster. These toxins usually originate from algae blooms. Symptoms of shellfish poisoning depend on the type of toxin and can include:
- Numbness and tingling
- Headache
- Nausea
- Vomiting
- Diarrhea
- Confusion
Prevention Tips:
- Avoid eating shellfish if you’re traveling in a low-income country or uncertain about the water quality.
- Be cautious about eating shellfish in areas that have recently experienced algae blooms, also known as “red tide” or “brown tide.”
Ciguatera: A Threat to Reef Fish Lovers
Ciguatera poisoning is caused by eating fish contaminated with toxins produced by algae found around coral reefs. The toxins don’t affect the appearance, taste, or smell of the fish, and they cannot be destroyed by cooking. Fish commonly associated with ciguatera include:
- Barracuda
- Moray eel
- Grouper
- Amberjack
- Sea bass
- Sturgeon
- Parrotfish
- Surgeonfish
- Red snapper
Signs and Symptoms:
- Nausea

Prevention Tips:
- Limit consumption of fresh reef fish, especially barracuda and moray eel.
- Avoid eating fish liver, intestines, eggs, or head, as they have the highest concentration of toxins.
