1. Choose Reputable Restaurants

When it comes to seafood, not all places are created equal.
look for spots that seem busy and popular-if locals are lining up, you're probably in the right place.
high turnover means the fish hasn't been sitting around for hours, which is always a good sign.
ask around or check online reviews; sometime the best gems aren't flashy, but word-of-mouth counts for a lot.
Avoid places that feel too touristy or empty-they might cut corners just to keep prices low.
a restaurant with a visible kitchen can be reassuring.
if you see hygiene and care in action, you know they take food seriously.
check how long seafood has been displayed.
fresh fish shouldn't be left out in the sun or under warm lights.
Don't hesitate to ask the staff how often they receive deliveries; the more frequent, the fresher the food.
lastly, trust your gut-if something seems off about a place, walk away.
it's better to miss a meal than risk feeling sick.
2. Avoid Raw or Undercooked Shellfish

Raw shellfish are delicious, but they can be risky, especially if you're pregnant, elderly, or have a weak immune system.
Even if you feel fine, bacteria and viruses can hide in oysters, clams, and mussels.
cooking seafood properly kills the nasties.
think of it as turning a potential stomach disaster into a tasty meal.
Raw dishes like ceviche or sushi should be approached with caution if you're in a high-risk group.
when in doubt, opt for fully cooked shellfish-they still taste amazing and are way safer.
Restaurants with high hygiene standards usually label or explain their raw items clearly, so always ask questions.
remember, it's not about spoiling the fun; it's about enjoying the meal and not spending your evening in the bathroom.
3. Ensure Thorough Cooking

Cooked seafood is almost always safer.
fish, shrimp, crab, and lobster taste best when done right and fully cooked.
Avoid dishes where the inside is still translucent-salmon, tuna, and shellfish need proper heat.
Check how the seafood looks and smells; if it's off in any way, don't risk it.
Cooking also reduces exposure to bacteria, viruses, and parasites.
Even grilled or pan-seared fish can be perfectly juicy while being fully safe.
restaurants should follow strict cooking practices, but a quick question to your waiter doesn't hurt.
A little patience for thorough cooking beats a day of feeling unwell after your meal.
4. Be Cautious with Street Vendors & Buffets

street food is tempting, but seafood needs careful handling.
Buffets can be tricky-seafood sitting out for hours can get unsafe fast.
temperature is key.
Hot dishes should stay hot, cold dishes should stay cold.
check how long seafood has been sitting; if it looks like its been there all day, skip it.
street vendors may not always follow strict health standards, so pick wisely.
it doesnt mean avoiding them completely, just keeping a little extra awareness.
A small checklist: visible steam trays, ice for cold items, and frequent replenishment usually mean better safety.
5. Avoid Large Predatory Fish

big fish like swordfish, marlin, and king mackerel can contain higher mercury levels.
mercury can build up in the body, so moderation is key.
It's safer to stick to smaller fish like sardines, cod, or sole more often.
even occasional indulgence in big fish is okay, but don't make it a daily habit.
restaurants often list the type of fish on the menu; use that to make smarter choices.
Mercury exposure is more concerning for children and pregnant folks, so extra caution is wise.
pairing seafood with other dishes helps balance your diet and reduces risk from eating too much predatory fish.
6. Ask About Freshness and Origin

Don't be shy-asking about where the seafood comes from is completely normal.
freshness affects taste, safety, and your overall experience.
ask if the fish was caught locally or imported; local catches are often fresher.
If a restaurant seems evasive about sourcing, consider it a red flag.
some places even have daily boards listing the day's catch, which is a good sign.
Knowing the origin helps avoid fish that may have been in storage too long.
Friendly staff usually appreciate questions-it shows you care about quality, not just your stomach.
Seafood in barcelona is incredible, but a few simple precautions can make the experience way more enjoyable.
Stick to reputable spots, make smart choices about raw or large fish, and always check freshness.
your taste buds and tummy will thank you.
Eating safely doesnt have to be stressful-it just means enjoying the flavors without the risk.
