DA-BFAR finds low-level contaminants in fish samples from oil-spill hit areas


The Department of Agriculture-Bureau of Fisheries and Aquatic Resources (DA-BFAR) found low-level contaminants or polycyclic aromatic hydrocarbons (PAH) in fish samples collected from oil spill affected areas, and recommended the extension of the fishing ban pending further investigation.

PAH is harmful to humans and other living organisms. It may accumulate in the flesh of fish over time.

However, the DA-BFAR said the results of the analyses are not yet conclusive as far as food safety is concerned.

Further sampling and analyses are being conducted to establish time-series results on the effect of the oil spill on fish concerning food safety, taking into account the magnitude of the oil spill, which has reached neighboring areas like Caluya, Antique and some municipalities of Palawan.

Meanwhile, preliminary findings showed that traces of petroleum products, particularly oil and grease, were detected in water samples—equivalent to <5 mg/L.

The figure is within the standard range of 3 mg/L to 5 mg/L set by the Department of Environment and Natural Resources in Administrative Order 2016-08.

To recall, the DA-BFAR collected water samples from different sampling sites from March 3 to 14, 2023. During the same period, the bureau collected fish samples from the municipalities of Naujan, Pola, Pinamalayan, Bansud, Gloria, Roxas, Mansalay, Bongabong, and Bulalacao in Oriental Mindoro.

These two types of samples were both analyzed within 10 days from the sample collection, based on the standard turnaround period for fish sample analysis.

In the meantime, the DA-BFAR recommended the continuous suspension of fishing activities in  selected areas in Oriental Mindoro for public safety.

The bureau also advised local government units (LGU) concerned to heed this science-based recommendation.

The DA-BFAR said it will continuously analyze water and fish samples in affected areas to monitor the possible spread of contamination and determine the extent of damage caused by the oil spill in the fishery sector.

The results will be shared with the public as soon as data becomes available, the bureau said.

According to the DA-BFAR, separate tests on water and fish samples are being conducted in Caluya, Antique, which has also declared a fishing ban.

The DA-BFAR will present its recommendation to the Caluya LGU upon the release of test results.

The DA-BFAR has already allocated an initial budget of P6.4 million for livelihood and relief assistance to aid affected fisherfolk and their families cope with the loss of income due to fishing bans.

The amount includes the P1.5 million worth of food packs provided by the DA-BFAR through its regional office in Mimaropa, which benefitted 5,000 oil spill-hit families in Oriental Mindoro.

The DA-BFAR has been monitoring the situation in areas affected by the oil spill in Oriental Mindoro.

It has also been evaluating contaminant levels in water and fishery resources to determine if seafood is safe for public consumption and if fishing bans should be imposed or lifted by the LGUs concerned.
