MANILA - The foul smell in parts of Muntinlupa may be attributed to decaying algae in Laguna Lake, Muntinlupa's health office said Thursday.
In an advisory, the Muntinlupa City Health Office said the stench can be attributed to the growing number of "liya" - a filamentous freshwater green algae present during warm weather - in Laguna Lake. It also serves as the fish's food and gives off a foul smell when decaying.
The health office said they received complaints that residents experienced difficulty in breathing, asthma attacks, stomach pains, and nasal clogging.
However they claimed that these health problems had "no direct link" with the spread of liya.
"Mahalagang magkaroon ng tamang kaalaman tungkol dito na ang liya ay walang direktang masamang epekto o banta sa ating kalusugan," they said.
"Gayunpaman, inaabusuhan ang lahat na agad magpakonsulta sakaling may hindi magandang maramdaman," they added.
(It's important for us to be informed about the fact that liya doesn't have direct adverse effects to our health. Nonetheless, we are calling on the public to seek medical attention if you feel bad.)
The health office reminded the public to take necessary precautions such as wearing face masks or staying inside a well-ventilated place.
It also reminded its residents to seek medical attention when they feel they have difficulties in breathing.
The local government said it is coordinating with its agencies and the lake's management to remove the dried and decayed liya.
