Can amoeba live in carbonated water

Headline

About half of all illnesses in countries with poor hygiene standards can be traced back to contaminated drinking water. Therefore, travelers should follow some basic rules in connection with drinking water.


water

  • Do not drink tap water
    Basically, tap water should never be drunk in the tropics and subtropics (not even in good hotels).
  • Drinking water filtering
    Good filter systems can filter out numerous types of bacteria, parasites and worm eggs. Viruses are rarely recorded, however. Before the water is filtered, the water should be boiled for at least 5 minutes. Note that when hiking at higher altitudes, the cooking time must be increased due to the lower atmospheric pressure. Boiled water should not be used after 24 hours at the latest, as new germs can develop on the surface of the water over time.
  • Drinking water disinfection
    Disinfection takes place using chemical agents in the form of tablets, powder and liquid in boiled water. After a reasonable exposure time, the water can then be used. However, not all pathogens can be detected even when the drinking water is disinfected.
  • Be careful with ice cubes
    If the water source of the ice cubes is contaminated, bacterial species (such as salmonella, shigella, etc.) or viruses can be transmitted in this way.

beverages

  • There are no concerns:
    • Freshly brewed tea and coffee (sufficient bubbling water can destroy pathogens such as hepatitis A viruses, amoebas or bacteria)
    • Carbonated drinks or lemonades from industrially closed containers (e.g. Coke cans, water bottles, etc.)
    • Alcohol does not usually contain any pathogens, but wine can occasionally be contaminated with fungi.
  • Dangerous are:
    • "open" and non-industrial beverages
      Drinks that are offered from unsealed bottles should be consumed with caution.
    • Milk should never be drunk fresh or uncooked. Boiled or pasteurized milk can be drunk.
    • Fruit juices should only be drunk if the pressing device and the hands that are in contact with the fruit are hygienically clean and clean. In the case of closed fruit juices, please note the sugar content, as it is a good breeding ground for bacteria.

food

In many countries, human feces are still used as fertilizers. Therefore, careful hygiene precautions for food intake are absolutely necessary here. Food from street stalls or cheap street restaurants should be avoided if possible, as the necessary hygiene measures can usually not be observed when preparing food.


  • There are no concerns:
    • freshly cooked vegetables
    • freshly peeled fruit (preferably peeled yourself)
    • well-done meat
  • Dangerous are:
    • raw meat (e.g. tartare, sliced ​​poultry, cold cuts, ham)
    • raw fish (sushi, cold seafood, oysters, etc.)
    • Salads of all kinds (especially egg or potato salad)
    • Dairy products (yogurt, quark, pudding, cream desserts, etc.)
    • Frozen food (interruption of the cold chain is possible)
    • Ice cream
