MANILA, Philippines – The Department of Health (DOH) urged the public to wait for test results on Manila Bay’s chemical and physical quality, as well as its coliform levels, before they go for a swim.
“The public is strongly advised to wait until the waters are deemed safe for recreational swimming,” the DOH said in a statement on Monday, February 4.

The DOH is coordinating with the Department of Environment and Natural Resources for the results of the tests.
The DOH warned the public that swimming in water with high levels of coliform can lead to waterborne gastrointestinal diseases.
These include diarrhea, cholera, typhoid, dysentery, skin diseases, and eye infections, which may be contracted when swimming in polluted waters. If not treated immediately, these diseases can lead to complications or death.
Coliform is usually associated with contaminants such as fecal matter. The DOH said a safe level of coliform in waters is 100 mpn (most probable number) per 100 milliliters. (READ: 3 restaurants found polluting Manila Bay, water cut off)
