(HealthDay News) -- Travelers' diarrhea is a frequent menace for international travelers. The culprit may be bacteria, a virus or a parasite.

The U.S. Centers for Disease Control and Prevention offers these suggestions to help reduce your risk of travelers' diarrhea:

• Don't eat or drink anything from a street vendor.
• Don't obtain food or drink from any facility that appears unclean.
• Don't eat any meat or seafood that is raw or appears undercooked.
• Don't eat any raw vegetables or fruit (i.e. oranges, bananas) unless you peel them yourself.
• Avoid tap water and ice.
• Avoid drinking or eating unpasteurized dairy products.
