Ecuador

Avoid drinking tap water — use bottled or reliably filtered water for drinking and brushing teeth, and avoid ice. Wash or peel fruit with bottled water; showers are generally fine.

Quito's tap water is treated but distribution and occasional infrastructure issues can pose a risk to visitors; drink bottled or use a reliable filter/boiled water. Avoid ice and wash or peel produce using bottled water if unsure of the source.
