That white stuff oozing out of your salmon as it cooks is just coagulated protein, and it's perfectly safe to eat. According to America's Test Kitchen, as salmon cooks, its muscle fibers contract, causing it to wring out the fish's internal protein, or albumin.
First: spot the difference. Farmed salmon is typically a lighter, more peach or orange colour than wild-caught salmon. If you do not have two pieces of salmon side-by-side for comparison, a good indicator that the salmon in your hand is farmed are visible lines of white fat.
