Today’s post continues from yesterday’s Part 1 about illnesses while traveling caused by unsafe and unsanitary food and water. Please see Part 1 here.
Waterborne Illness
Contaminated water is another significant risk for travelers, especially in regions where tap water is not treated to the same standards as developed countries. Drinking contaminated water or using it to wash food can lead to severe illnesses, such as cholera, dysentery, and hepatitis A.
1. Drinking Tap Water: In many parts of the world, tap water is unsafe. It may contain pathogens like bacteria, viruses, parasites, and harmful chemicals. Even where locals drink tap water without issue, travelers can get sick because their bodies are unfamiliar with the local microorganisms. Always opt for bottled or purified water, and make sure the seal is intact before drinking. Carrying a portable water filter or purification tablets can also be a reasonable precaution.
2. Ice and Beverages: Ice is often made from tap water, so even if you avoid drinking it, consuming beverages with ice can still pose a risk. Similarly, juices, shakes, or other drinks that may have been diluted with local water can be hazardous. Drinking sealed, boiled beverages (like tea or coffee) from boiled water is safer when in doubt.
3. Swimming and Recreational Water: Illnesses can also be contracted from swimming in contaminated water. Lakes, rivers, and even some swimming pools may harbor pathogens that can cause gastrointestinal or skin infections. Accidental water ingestion while swimming, particularly in natural bodies of water or untreated pools, can lead to diarrhea, nausea, and other symptoms.
Risks of Poor Sanitation and Hygiene
Poor sanitation and hygiene are often the root causes of food and water contamination. In some regions, wastewater treatment and sanitation infrastructure may be inadequate, leading to the spread of disease through contaminated food and water sources.
1. Poor Hand Hygiene: Not washing hands thoroughly before eating or preparing food is a significant risk factor for illness. In areas where soap and clean water are scarce, hand sanitizer with at least 60% alcohol can be a vital tool for maintaining hand hygiene. Additionally, be cautious about touching your face, especially your mouth and eyes, with unwashed hands.
2. Inadequate Sanitation Facilities: Public sanitation facilities may be lacking or poorly maintained in many places, especially in rural or developing regions. This can increase the risk of coming into contact with harmful pathogens. When using public restrooms, it’s essential to be mindful of hygiene practices, such as using a tissue or sanitizer to avoid touching surfaces directly.
Mitigation Strategies
1. Be Informed: Research your destination’s food and water safety standards before traveling. The Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) provide up-to-date information on food and water safety in different regions.
2. Vaccinations: Some food and waterborne diseases, such as hepatitis A and typhoid fever, can be prevented through vaccination. Consult with a healthcare provider before your trip to determine if any vaccines are recommended for your destination.
3. Pack Essentials: Bringing along essential items like a portable water purifier, hand sanitizer, and oral rehydration salts can help you manage minor illnesses and stay safe.
4. Eat and Drink Safely: Stick to bottled or boiled water, eat well-cooked food, avoid raw or undercooked dishes, and choose food from reputable sources.
The risks of getting sick from food and water while traveling can be significant, but with proper precautions, they are manageable. By being vigilant about what you eat and drink and maintaining good hygiene practices, you can significantly reduce your chances of falling ill and enjoy a safe and healthy trip.
Be well.
