Is salmon classified as red meat?

No! Nor is it really "White Meat". It is classified as fish meat, so therefore, it is white meat, but it is sold as pink or red. The red coloring is from the pigments in crustaceans that the salmon eats. Occasionally, a salmon will lack the ability to process the pigments during digestion, and the meat will be white. Approximately 1 out of every 20 salmon is actually white.
