Hotels, restaurants, and households generally use ice made from filtered drinking water supplied by ice companies. It is rare for restaurants to use ice made directly from tap water, so it is relatively safe to consume.
Some travelers may feel uneasy about ice in drinks or water, but it’s difficult to be completely cautious since nearly all places use the same type of ice. Even if the ice itself is clean, unfamiliar water can sometimes upset your stomach.
If you are in good health, the risk of stomach issues or other discomfort is significantly lower, so managing your health carefully is recommended.
Additionally, it is strongly advised to have travel insurance in case of unexpected health issues while abroad.
