Meat is an indispensable food in our lives, and most parts of an animal can be consumed. However, there are some parts that you should never eat, as they can easily cause health problems. In animals such as pigs, cattle, and sheep, the thyroid, adrenal glands, and diseased lymph nodes are three "physiologically harmful organs".
Poultry "Tail Bud"
The part on poultry like chickens, ducks, and geese at the top of the buttocks where the tail feathers grow, known scientifically as the "cloaca bursa", is an area 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 bud" is a "warehouse" that harbors filth.
Rabbit "Scent Glands"
The white inguinal glands located under the skin on both sides of the external genitalia, the brown inguinal glands closely adjacent to them, and the anal glands located on the walls of the rectum are extremely fishy and foul-smelling. If they are not removed during preparation, the rabbit meat will be difficult to eat.
Livestock "Three Glands"
In animals such as pigs, cattle, and sheep, the thyroid, adrenal glands, and diseased lymph nodes are three "physiologically harmful organs".
Sheep "Suspensory Ligament"
Also known as "hoof pearls", it is generally round, bead-like, or串粒状 (string of beads) and is a tissue that has become diseased inside the sheep's hoof.
Fish "Black Membrane"
On both sides of the fish's body cavity, there is a layer of black membrane. This is the most fishy and earthy-tasting part and contains large amounts of lipids, lysozyme, and other substances.
