1. Sausages are prone to mildew if they are kept for a long time. Clinically, moldy sausages are contaminated by a highly toxic botulinum. People will cause food poisoning after eating contaminated sausages. Many people eat hot dogs and ham sandwiches every day, but they don't know that these processed foods are hidden dangers: there are not only a lot of ptomaine and pesticides, but also a variety of carcinogens. In order to save your life, it is better to stay at a respectful distance from others. In recent years, more and more scientific evidence confirms that eating sausages and ham will greatly increase the risk of cancer. As early as 1950s, scientists discovered that nitrosamines, a chemical, could cause liver cancer. 1954, four chemists in a British university suffered from cirrhosis at the same time, and one of them died. The investigation found that they ate dimethylnitrosamine in the experiment. Two years later, more animal experiments confirmed that dimethylnitrosamine can cause liver cancer. A chemist in Germany quietly put a small amount of nitrosamines in jam for his wife to eat every day. As a result, she was poisoned and didn't know that her husband had murdered her. In the process of making sausages, ham, barbecued pork, sausages, lunch meat, salted beef and other foods, nitric acid is added to react chemically with heme in the meat, which looks beautiful and pink, and also has the function of sterilization and preservation. After these nitric acids are eaten in people's stomach, they will be decomposed into nitrous acid, which will react with the amine contained in meat and become nitrosamines. Eating too many hot dogs is easy to get fat. Hot and dry
