Water sample from a food establishment in Baguio City has tested positive for fecal contamination but the finding, authorities said, is not enough “to answer for the whole city” for its diarrhea outbreak. 

"We cannot say one positive [is enough]. It's not enough to answer for the whole city, so it is not conclusive according to our health authorities,” said Aileen Refuerzo, the city’s public information officer. 

Majority of the samples sent for testing were found negative for coliform organisms.

Water from the reservoir in Mount Santo Tomas, which serves as a rain harvesting facility, was also tested.

"Katulad sa amin sa water district, siguro possible na diretso ‘yan [na water testing for] one week so we can really prove na negative sa contaminants ang aming supply,” Mark Pasagoy, Baguio Water District PIO, said.

As of this writing, the total number of diarrhea cases has reached 2,764 but the City Health Services Office said the number of new cases declined in the past two days. 

"It appears that our containment and preventive measures are effective. Now, we will concentrate on investigation," said Baguio City Mayor Benjamin Magalong.

In line with this, the local government warned businesses that might take advantage of the situation by increasing the prices of purified water.

The public is urged to report any price hike to the Department of Trade and Industry (DTI).
