Sen. Maria Cantwell is calling for stronger communication between American and Canadian officials following the disclosure that Canada failed to reveal the results of tests that appear to show the presence of a potentially deadly salmon virus nearly a decade before a salmon-virus scare this fall.

A Canadian researcher's work surfaced this week after she sought and was denied permission by a Canadian official to try to have her old data published.

Researchers with Simon Fraser University in British Columbia announced in October they had detected infectious salmon anemia, or ISA, in two wild juvenile Pacific salmon collected from the province's central coast, prompting fears the influenza-like virus could wreck the Pacific Northwest salmon fishing industry.

U.S. scientists say they're disappointed the Canadians never mentioned the researcher's earlier, 2002 work.
