Wash Your Hands!
Avoid swallowing recreational water
- Recreational water is water in swimming pools, hot tubs, jacuzzis,
fountains, lakes, rivers, springs, ponds, or streams that can be contaminated
with sewage or feces from humans or animals.
Note: Crypto is chlorine resistant and can live in pools for days.
- Healthy Swimming
CDC; Contains information on recreational waterborne illnesses. Attention: Non-MDH link
- Avoid using ice or drinking water when traveling in countries
where the water supply might be unsafe.
- Avoid eating uncooked foods when traveling in countries
with minimal water treatment and sanitation systems.
Avoid drinking untreated water
- Untreated water can come from shallow wells, lakes, rivers,
springs, ponds, and streams.
If you are unable to avoid drinking water that might be contaminated, then treat the water yourself by:
- Heating the water to a rolling boil for at least 1 minute.
OR
- Using a filter that has an absolute pore size of at least 1 micron
or one that has been NSF-rated for "cyst removal."
