Food and water safety precautions play a prominent role in the “CDC Yellow Book 2020.” The Yellow Book, published every other year for half a century is the world travelers’ handbook for staying healthy.
Chapter 2 provides blunt warnings for international travelers about the risk of contaminated food and water. It says: “Swallowing, inhaling aerosols of, or coming in contact with contaminated water — including natural freshwater, marine water, or the water in inadequately treated swimming pools, water playgrounds (splash parks or splash pads), or hot tubs and spas — can transmit pathogens that can cause diarrhea, vomiting, or infection of the ears, eyes, skin, or the respiratory or nervous system”
Yellow Book 2020’s food and water warnings go on to include raw and undercooked meat, fish, and shellfish. The risks of toxins are enough to take the romance out of tropical waters. Travelers are encouraged to wash their hands often with soap and water or use those alcohol-based hand sanitizers. Both require proper techniques to be effective.
“In many parts of the world, ” the book adds, “particularly wher water treatment, sanitation, and hygiene are inadequate, tap water may contain disease-causing agents, including viruses, bacteria, and parasites, or chemical contaminants. As a result, tap water in some places may be unsafe for drinking, preparing food and beverages, making ice, cooking, and brushing teeth.”
While disclosing all the dangers, the Yellow Book wants travelers to “stay healthy while enjoying the sights, activities, and cultures of countries around the world. As travelers plan the details of their itinerary, clinicians can use the Yellow Book to help inform their health protection strategy.”
The Yellow Book offers readers current U.S. government travel health guidelines, including pre-travel vaccine recommendations, destination-specific health advice, and easy-to-reference maps, tables, and charts.
CDC’s travel health experts wrote the Yellow Book as a reference for health care providers, including doctors, nurses, and pharmacists. Other audiences that find the Yellow Book to be a helpful resource include:
