Modern medical research shows that there are more than 200 types of bacteria, viruses, and other harmful substances in meat from livestock, poultry, and fish that can be transmitted to humans. Even certain organs with normal physiological functions can affect human health if mistakenly consumed, and may even lead to food poisoning.
1. The "three glands" of livestock: These refer to the thyroid, adrenal glands, and diseased lymph nodes in animals such as pigs, cattle, and sheep. Mistakenly consuming the thyroid can cause hyperthyroidism, with symptoms including dizziness, headache, excitability, mania, convulsions, fatigue, palpitations, rapid pulse, loss of appetite, nausea, excessive sweating, and fever.
2. The "sharp tips" of poultry: These are the pointed tips of chickens, ducks, geese, and other fowl, specifically the area above the tail where the tail feathers grow. This area is a concentration of lymph nodes in poultry. Because macrophages in the lymph nodes have a strong ability to phagocytize bacteria and viruses, the sharp tips of poultry become a "repository" for filth. Consuming them can easily lead to disease.
3. The "suspended tendons" of sheep: Also known as hoof pearls, these are diseased viral tissues found within the hooves of sheep, typically appearing as strings of beads or round shapes. They must be removed before consumption.
4. The "black membrane" of fish: Most fish have a layer of black membrane on both sides of their abdominal cavity. This is the most foul-smelling and earthy-tasting part of the fish's body, and it contains large amounts of histamine, lipids, and lysozyme. Mistakenly consuming histamine can cause symptoms such as nausea, vomiting, and abdominal pain.
