Yes, salmon skin is edible and can be eaten safely when cooked properly. It is actually quite nutritious, containing omega-3 fatty acids, protein, vitamins B and D, and minerals like selenium. Many people enjoy its crispy texture when seared, grilled, or pan-fried. However, it is important to consider the source of the salmon because salmon skin can accumulate environmental toxins, particularly in farmed salmon. Wild-caught salmon from the Pacific Ocean is generally regarded as the safest choice for consumption. Cooking the skin well also helps ensure safety. In summary, salmon skin is not only edible but also provides added nutritional benefits and can be delicious when prepared correctly, especially by crisping it up in cooking. Just be mindful about the source and quality of the fish to reduce exposure to contaminants.
