💧 Water Safety Guidelines (CDC 2026)
Critical Rule: Avoid Tap Water in Areas with Questionable Water Quality
Tap water can be contaminated with amoebas, parasites, and viruses including hepatitis. This includes water for: cocktails, ice cubes, brushing teeth, washing fruits, and rinsing contact lenses.
✅ SAFE Water Sources
- •Sealed Bottled Water: Check seal is intact before drinking
- •Carbonated Drinks: Bubbles indicate factory sealing (safer than still water)
- •Boiled Water: Bring to rolling boil for 1 minute (3 minutes above 6,500 ft/2,000 m)
- •Filtered Water: Use CDC-approved filters (0.1-1 micron absolute pore size)
- •Disinfected Water: Iodine or chlorine tablets (follow instructions carefully)
- •Hot Beverages: Coffee and tea made with boiled water
❌ AVOID These Water Sources
- •Tap Water: For drinking, ice, tooth brushing in high-risk countries
- •Ice Cubes: Often made from tap water (even in nice restaurants)
- •Fountain Drinks: Mixed with local tap water
- •Unpasteurized Juice: May be diluted with contaminated water
- •Water from Lakes/Rivers: Even if locals use it
- •Hotel Tap Water: In areas with poor sanitation (even luxury hotels)
💡 Pro Tip: The "Carbonation Test"
When ordering bottled water, choose carbonated (sparkling) water when available. The bubbles prove the bottle was sealed at the factory and hasn't been refilled with tap water—a common scam in some countries.
🍜 Street Food Safety Guide
CDC Advisory: Consumption of food from street vendors increases the risk of illness. However, street food is often a highlight of international travel. Follow these guidelines to enjoy it safely.
✅ Signs of Safe Street Food
- ✓High Turnover: Long lines of locals = food is fresh
- ✓Cooked to Order: Watch food being prepared fresh and hot
- ✓Clean Setup: Vendor wears gloves, uses separate utensils
- ✓Steaming Hot: Food served above 140°F (60°C) kills most bacteria
- ✓Visible Kitchen: You can observe food handling practices
⚠️ Red Flags to Avoid
- ✗Pre-Cooked Food: Sitting out at room temperature
- ✗Raw Ingredients: Especially meat, seafood, eggs in hot climates
- ✗Dirty Conditions: Flies on food, dirty utensils, no gloves
- ✗Lukewarm Food: Not hot enough to be safe
- ✗No Local Customers: If locals avoid it, you should too
