DUMAGUETE CITY—The Bureau of Fisheries and Aquatic Resources (BFAR) has heightened its surveillance of coastal areas in Negros Oriental for possible red tide occurrences, particularly focusing on the region's bays following a recent red tide warning.

According to the Philippine News Agency, the BFAR issued an advisory over the weekend cautioning against the consumption of shellfish from Bais Bay, where tests last month revealed high levels of paralytic shellfish poison (PSP). Florencia Mepaña, the chief of BFAR-Negros Oriental, noted that ongoing efforts include sampling in Tambobo Bay and Siit Bay in Siaton, with plans to extend testing to Bais City on Tuesday.

Mepaña emphasized the importance of local collaboration, stating that local government units, particularly in Bais City, have been alerted to warn residents against collecting, selling, or consuming shellfish from affected areas. The response also includes coordination with business owners throughout the region, ensuring compliance with restrictions and maintaining public safety against shellfish poisoning.

In addition to local efforts, 'Bantay Dagat' (sea watch) volunteers have been mobilized to monitor Bais Bay and prevent the distribution of potentially contaminated shellfish. Although there have been no recent incidents of shellfish poisoning reported, the region remains vigilant, recalling previous red tide events in 2015 and 2017.
