🚰 Tap Water in Spain: What You Need to Know About Nickel Allergy 🇪🇸
â €
Many tourists and even locals often ask: is it safe to drink tap water in Spain? 🤔
The answer is yes! According to OCU, 99.55% of Spain’s tap water is considered safe. In most regions, its quality is comparable to bottled water, and strict controls guarantee reliability.
â €
✨ But here’s an important detail: people with a nickel allergy should follow one simple rule — do not drink the first flow of water from the tap.
â €
🔎 Why is this important?
According to EFSA and AESAN, in the first few seconds, tap water may contain higher levels of metals — nickel, copper, and lead. This depends on the pipes, faucet materials, and how long the water has been standing.
â €
👩‍⚕️ For most people this is harmless, but for those with nickel sensitivity, even a sip can cause:
✔️ itching and redness;
✔️ rashes and irritation lasting 2–4 weeks;
✔️ discomfort on eyelids, fingers, or palms.
â €
🥗 Besides water, nickel is also found in foods. If you are sensitive, it’s better to avoid:
❌ chocolate and cocoa,
❌ nuts and seeds,
❌ seafood and fish (salmon, tuna, mackerel),
❌ oats, corn, and soy.
â €
And here’s what you can safely include in your diet:
âś… apples, bananas, oranges, strawberries, tangerines;
âś… potatoes, carrots, cucumbers, cabbage, onions;
âś… rice, meat, poultry, dairy, and eggs;
âś… olive oil and mushrooms.
â €
🌍 Overall, the quality of tap water in Spain is among the best in Europe. So drink with confidence — just remember this simple tip: let the first flow of water run before drinking. This way, you’ll stay healthy and enjoy fresh, safe water straight from the tap. 💧
