The thyroid, adrenal glands, and diseased lymph glands on animals such as pigs, cattle, and sheep are three "physiologically harmful organs". Sheep "Suspensory Ligament"
Also known as "hoof pearl", it is generally round or beaded, and is a tissue that develops abnormally within the sheep's hoof. Rabbit "Odor Glands"
The inguinal glands located under the skin on both sides of the genitalia, the brown anal glands adjacent to them, and the rectal glands located on both sides of the rectal wall have an extremely strong and foul odor. If not removed before consumption, they will make the rabbit meat inedible. Poultry "Tail Tip"
The area at the top of the poultry's (chicken, duck, goose, etc.) buttocks where the long tail feathers grow. Its scientific name is "cloaca", and it is a place where lymphoid glands are concentrated. Because the macrophages in the lymphoid glands can engulf bacteria, viruses, and even carcinogens but cannot break them down, the poultry "tail tip" acts as a "repository" for filth. Fish "Black Membrane"
There is a layer of black membrane on both sides of the fish's abdominal cavity, which is the most foul-smelling and earthy-tasting part, containing a large amount of substances such as lipids and lysozyme.
