The common definition considers red meat as a meat with a darker color before and after cooking. However, in nutrition, red meat is defined as any meat that has more myoglobin than white meat. Red meat is defined as all meats obtained from mammals (regardless of cut or age) as they have more myoglobin (United States Department of Agriculture). This includes beef, veal, lamb, pork, and also a leg of chicken and turkey (the latter are considered white by common definition). Fish and poultry (excluding legs) are considered white meat.
