As any traveler knows, after a long plane, train, and/or bus ride, all you want to do is take a shower, change your clothes, take a nap and get some grub! The last thing you want is to wind up back in bed or the bathroom with a sour stomach…or worse, the hospital. While there are several sources of health risk to travelers, the most common is contaminated food and water. Travelers trying exotic and exciting foods should follow these simple rules: cook it, wash it, peel it or forget it! And do not forget about ice. Freezing water does not remove contaminants and even alcoholic drinks are risky with contaminated ice.
There are several other sources of risk: poor sanitation and other diseases. Before you go, check out the World Health Organization (WHO) and with the Center for Disease Control (CDC) for risks at your destination. It is also extremely important to get any vaccinations recommended for your destination. The CDC has detailed documentation on requirements for each country.
Many diseases and infections are transferable between people. Sick people are also an indication that there may be a disease source near by—such as insects or poor sanitation. It is also important to be aware of how much sun/cold/oxygen you are exposed to. Too much sun exposure can lead to severe sunburns and dehydration. Sun block is expensive and not a common feature in many developing countries’ convenience stores. Observe local customs for avoiding the extreme weather and bring sunblock with you.
Most importantly for food, however, cook it, wash it, peel it or forget it.
