SALEM (AP) — Health officials in Oregon and Washington said Monday that people should protect themselves against mercury and PCB contamination by limiting consumption of certain fish species from a 150-mile section of the Columbia.
The Oregon Health Authority and the Washington Department of Health said people should eat no more than one meal a week of resident fish — those that live year-round in the same place — between Bonneville and McNary dams. Resident species in the Columbia include bass, bluegill, yellow perch, crappie, walleye, carp, catfish, suckers and sturgeon.
A meal is about the size and thickness of one’s hand.
Officials also recommend not eating any resident fish taken between Bonneville Dam and Ruckel Creek 1 mile upstream.
The advisory does not apply to migratory fish, such as salmon and steelhead, because they spend most of their time at sea.
“We’ve suspected for quite some time that there may be contamination in the Columbia River, and the thing that was missing was measured data,” said Dave Farrer, public health toxicologist for the Oregon Health Authority.
Only recently have researchers had the resources available to measure toxicity in Columbia River fish, he said. The states said they’re unsure how long the advisory will last.
Polychlorinated Biphenyls, or PCBs, are toxic chemicals that do not break down in the environment. They were widely used in electronic components until they were banned in the Toxic Substances Control Act of 1976.
Officials advised against eating any fish near the Bonneville Dam after researchers measured extraordinarily high levels of PCB contamination in resident fish there. The most contaminated sample measured 183 parts per million, Farrer said, and the threshold for an advisory is 0.047 ppm.
Upstream from Bonneville, mercury is the concern, Farrer said.
Mercury and PCBs build up over time. Developing fetuses, nursing infants and small children are most vulnerable to their negative health effects, so it’s especially important that women of child-bearing age heed the advisories, officials said.
Officials recommend pregnant women eat migratory fish for the beneficial protein, omega-3 fatty acids and other nutrients.
“The message isn’t to not eat fish at all,” Farrer said. “We want people, especially pregnant women, to eat fish. We just want them to choose fish correctly. We hope these advisories are a good tool to help them.”
Native American leaders called on the state and federal governments to focus on improving water quality, noting that members of Columbia River tribes rely on fish for a substantial portion of their diet.
Yakama Nation Chairman Harry Smiskin said in a statement. “This is unacceptable. The focus should not be ‘Do not eat.’ It should be ‘Clean up the Columbia River.’”

Parkdale third graders sing "12 Disaster Days of Christmas"
Welcome to your sing-able Christmas gift list. What follows is an emergency rendition of “12 Days of Christmas” – for outfitting your home or car in case of snow storm, earthquake, flood or other emergency. Read it as a simple list, or sing it to the tune of “12 Days” – you know, as in “ … and a partridge in a pear tree…” Not to make light of it, but the song is a familiar framework for a set of gift ideas that you could consider gathering together, even if the recipient already owns items such as a bunch of coats, tire chains and flashlights. Stores throughout the Gorge are stocked up on all these items. Buying all 12 days might be prohibitive, but here are three ideas for checking any of the dozen off your list (notations follow, 1-12.) The gift items needed to stay warm, dry and safe are also coded to suggest items in your abode (A) in your car (C) or both (B). 12 Gallons of Water (A) 11 Family meals (B) 10 Cans of propane (A) 9 Hygiene bags (B) 8 Packs of batteries (A) 7 Spare coats (B) 6 Bright red flares (C) 5 Cozy blankets (B) 4 Tire chains (C) 3 Flashlights (B) 2 cell phone chargers (B) 1 And a crush-proof first aid kit (B) Price ranges? Here’s a few quotes for days Three, Two, Four and Nine: n A family gift of flashlights (three will run $15-30, Hood River Supply, Tum-A-Lum) n Cell phone chargers (two will run $30-60) n Tire chains (basic set, $30, Les Schwab, returnable if unused for the winter) n Family meals ($100 or so should cover the basics for three or four reasonably well-fed days) n The home kit should be kept in a handy place near an exit, and remember that water needs to be replenished every few months. If you have a solid first aid kit already, switch out the gift idea with “and-a-sto-o-u-t- tub-for it-all …” Otherwise, it’s a case of assembling your home or car kits and making sure all members of the family know what the resources are and how to use them (ie flares and propane). Emergency situations are at worst life-threatening, at best deeply uncomfortable if you and your family are left without power for an extended period, or traveling and find yourself in a situation where you need to wait out a storm, lengthy traffic delay, or other crisis. Notes on the 12 gift ideas: 12 – Gallons of water: that’s one per person in a four-member family to last for three days, the recommended minimum to be prepared for utility outages. 11 – Easy-open packaged goods, energy bars, dried food and nuts are good things to include for nutrition. Think of what your family of four needs for three days to stay fortified and hydrated (see number 12). Can-opener also recommended 10 – If you have a propane camping stove, keep extra fuel handy. 9 – Hygiene bags: put packaged moistened towelettes, toilet paper, and plastic ties in large garbage bags (for personal sanitation) Resource list courtesy of Hood River County Emergency Management, Barbara Ayers, manager/ 541-386-1213. The county also reminds residents to Get a Kit, Make A Plan to connect your family if separated, and Stay Informed. See www.co.hood-river.or.us to opt-in for citizen alerts. Enlarge
