The Oregon Health Authority is expanding the advisory for fish caught in the Willamette River.

Advisory has now been expanded, it was announced Wednesday, to include the area from the Sellwood Bridge up to the Sauvie Island Bridge and the Multnomah Channel.

OHA officials say fish caught in those areas of the Willamette River could contain dangerous chemicals known as PCBs.
