The companies have confirmed that Tembec added melamine as part of the formulation of the products to improve the binding properties of pelleted feed. Melamine is not approved as an additive for animal or fish/shrimp feed.

The companies have stopped adding melamine to the feed products, the agency said.

As a result of this new information, ODFW hatchery managers have immediately discontinued using the additional recalled feed and have begun an inventory of all feed on hand at ODFW hatcheries and facilities.      They just begun ?

Majority of state-run hatcheries use feed linked to pet food recall (May 11)
More than three-quarters of the state-run hatcheries in Oregon used feed linked to the pet food recall.  The manufacture, Skretting Canada, made feed using wheat flour imported from China that was tainted with melamine.  Skretting recalled the tainted product May 8, they have 198 customers in the U.S.
 

Almost 4.5 million of those fish were released into the Columbia River within the past month, Reportedly those juvenile tule fall chinook salmon pose little risk to consumers because they are years from reaching dinner tables.  It does not appear that any legal-sized rainbow trout from our hatcheries were fed any of the recalled product,

The feed, which contained wheat flour tainted with melamine, has been recalled, and all Oregon hatcheries have stopped using the product.  The 26 operations that received recalled feed include the Sandy, Willamette, Cole Rivers, Oak Springs, Oxbow, Salmon River, Butte Falls, Cascade, Wizard Falls, Marion Forks, Bonneville, Leaburg, South Santiam, Bandon, Elk River, Rock Creek, Fall River, Nehalem, Trask, McKenzie, Gnat Creek, Umatilla, Cedar Creek, Klamath, Looking Glass and Big Creek hatcheries.

 Farmed fish in US fed contaminated material linked to pet food recall (May 8)
A portion of the mislabeled wheat gluten has been used in the preparation of fish feeds and has been used in some U.S. aquaculture production operations. Officials stated that levels of melamine in affected fish tested so far have been comparable to those found in hogs and chickens.  There continues to be no sign that melamine-tainted products are in human food, except for the tainted animal feed, according to Acheson.

Fish samples would be screened for signs of melamine. "Depending upon what we find in that testing, that is going to drive the next steps," said Dr. David Acheson, the FDA's assistant commissioner for food protection.
