Unfortunately, I cannot create a summary for this article because the full text of the Science article titled "Canada's dismantled safeguards threaten salmon" (Volume 391, Number 6782, January 2026) is not found in the search results provided. The search result [7] contains only the title and a short description, which says that the rapid progress with industrial projects to reduce surveillance increases the risk of irreversible damage to salmon, ecosystems and people. In order to create an accurate and factual summary as per your requirements, I would need access to the full text of the article.
