Safe drinking-water
Unlike Mexico, Jamaican has safe drinking-water. It's things to know before traveling to Jamaica. When eating out, travelers do not need to worry about drinking bottled water, cleaning their teeth with tap water, or avoiding raw vegetables for fear of becoming ill. Drink the tap water unless you're in a really isolated place with poor water purification.
In most parts of Jamaica, tap water is safe to drink, but unless it has been boiled, filtered, or otherwise treated, you should avoid drinking water directly from the faucet in more rural locations. The tap water in Jamaica is generally safe to drink. You may also brush your teeth, take a bath, prepare meals, wash clothes, and do other things using tap water (also known as pipe water in Jamaica).
Adding ice to your beverages is also an option. Piped water is not accessible in certain rural parts of Jamaica, which account for nearly a third of the country's land area and are far from major tourist locations, hence bottled water should be used.
