Is the Water Safe to Drinkin Cuba?
Water in Cuba sometimes has bacteria that causes diarrhea, and it is the cause of most travelers’ upset stomachs. Avoid tap water and buy bottled water whenever possible. Make sure that your bottled water has an unbroken seal. If bottled water is not an option, be sure to boil your water, or make sure to carry iodine purification tablets.
There is a chance that tap water in Cuba may carry cholera. Cholera causes sufferers to have diarrhea, which can become severe. The most recent outbreak of cholera in Cuba occurred in 2012.
Be wary of produce that has been washed in tap water. You should eat raw fruit and vegetables only if you have washed them first in purified water.
