Jordan is one of the cleanest and safest countries, but it is nonetheless advisable to take some precautions until your digestive system adjusts. Hotels rated four-star and up have their own filtering systems, and their tap water is safe to drink. In other places, bottled water is recommended. All fruit and vegetables should be washed thoroughly, and salads and cold meats which have been sitting out for a long time should be avoided, especially during summer months. All Jordanian dairy products are pasteurised and safe.
