Security in Puerto Rico - Most of the crime on the island occurs in and around the San Juan Metropolitan area and in the larger cities of Ponce and Mayaguez to a lesser degree. Most of that crime is directly related to the illegal drug industry, so you need not be unduly worried.
Old San Juan and other major tourist zones in Puerto Rico are safe and a police presence is visible. As with any large city, one should exercise prudence and avoid wandering into unknown areas of the city, especially at night and one should not leave valuables visible inside a parked rental car.
Other Risks - To be on the safe side while in Puerto Rico, drink bottled water. If you buy produce from a street market, wash and/or peel it before eating.
