1. Hot spicy dip
Cost:
Although mala Tang tastes delicious, it hides harm. Mala Tang is not inedible, but the following preventive measures must be taken: 1. The spicy pot should be cleaned in time and the ingredients should be cleaned. Because ordinary copper pots are easy to grow a thin layer of green rust after stopping using, which is harmful to human health. If the ingredients are imported directly, it will be cleaner, otherwise it will cause more diseases. 2. The fire at the bottom of the pot must be strong. If eaten before boiling, germs and parasite eggs are not completely killed, which is easy to cause digestive tract diseases. 3. Don't be too hot in Mala Tang Can. Because the data show that people's mouth, esophagus and gastric mucosa can only tolerate the temperature of 50℃-60℃, too hot food will damage the mucosa, leading to acute esophagitis and acute gastritis. 4. Mala Tang should not be too thick and spicy. Being too fat can easily lead to hyperlipidemia, gastropathy, duodenal ulcer, gallstones, oral ulcers, gingivitis and hemorrhoids. It is recommended to be light and moderately spicy.
At present, it is the high incidence of infectious diseases and gastrointestinal diseases. If the stall owner engaged in mala Tang business carries infectious bacteria such as tuberculosis, dysentery and hepatitis B, it will bring great harm to consumers.
2. Hairy eggs
Cost:
Hairy eggs are mostly used to hatch chickens. Due to improper temperature and humidity or infection with germs, their development stopped, and they died of chicken embryo eggs in eggshells. The nutritional composition of this kind of chicken embryo egg has changed, and almost all of them contain bacteria such as Escherichia coli, Staphylococcus, Typhoid Bacillus and so on. These things are very easy to be poisoned after eating, causing diseases such as dysentery, typhoid fever and hepatitis. Whether cooked or not, raw eggs will cause acute intestinal infectious diseases during frying. In addition, the hormone content in hairy eggs is particularly high, which will have a certain negative impact on the growth and development of teenagers. Therefore, young people had better eat less.
3. Roasted and salted mutton kebabs
Cost:
Is the kebab you eat really "mutton"? As a special snack, kebabs have always been very popular with the public. As we all know, in order to get more profits, some vendors have tampered with this kind of lamb kebabs. It is understood that many kebabs on the market now are actually cat meat, beef and even dead pork. Those substitutes are soaked in sheep oil and some seasoning water, and the smell is so bad that ordinary citizens can't tell them apart at all.
What most people don't know is that many barbecue raw materials, such as mutton skewers and squid, have serious hygiene problems, and often mutton brisket and mutton offal are processed into fake mutton skewers together with other leftovers. Many barbecue stalls recycle used bamboo sticks, which also easily leads to the spread of diseases. In the process of baking, if the food is baked too tender, you may get parasitic diseases after eating it. If the food is barbecued directly on an open flame, charcoal will not burn completely, and carcinogens will stay on the grilled food, which will be harmful if you eat too much. In the meat processing, according to the Regulations on Food Hygiene Management, frozen meat birds should be completely thawed before cooking, and then heated and cooked fully and evenly. For example, if the kebabs are not completely thawed, they will be barbecued directly. Conventional cooking temperature is not enough to kill microorganisms, and eating food with bacteria can easily lead to intestinal problems.
4. stinky tofu
Cost:
The stinky tofu stalls on the street basically have no hygiene license, which has great health and safety hazards. Most of these street stinky tofu are made of ferrous sulfate, an industrial raw material, which will be harmful to health if eaten too much. Some "black-hearted" tofu processing sites even use inferior additives, preservatives and colorants that are explicitly prohibited by the state. According to our understanding, the fermentation process of stinky tofu is carried out under natural conditions and is easily polluted by microorganisms. Stinky tofu contains a lot of volatile basic nitrogen, with an average of 4.9 grams per kilogram and an average of 16.5 mg of hydrogen sulfide per kilogram. These two substances are decomposed by protein and are harmful to human body. In addition, the use of Mucor in the early stage of stinky tofu fermentation is easy to be contaminated by other bacteria, including pathogenic bacteria. Therefore, don't eat too much stinky tofu at a time, so as not to cause gastrointestinal diseases.
5. Fried dough sticks and oil cakes
Cost:
Eating fried dough sticks for breakfast is a habit of many people, but in view of the harm caused by eating fried food and the possible adverse consequences of additives in it, Professor Li Yong, an expert in nutrition and food hygiene, suggested that everyone should eat fried dough sticks as little as possible, and healthy adults should not eat fried dough sticks more than twice a week, and the amount should not exceed twice each time. Li Yong told us that 80% of the aluminum in the fried dough sticks on the street exceeded the standard, and excessive intake of aluminum may cause dementia. Generally, when eating fried dough sticks, "diners" should carefully smell whether there is ammonia. If there is ammonia, it indicates that it may have used a bulking agent-ammonium bicarbonate. After the fried dough sticks are heated in the oil pan, ammonium bicarbonate is decomposed into ammonia and carbon dioxide at high temperature, and the generated gas will expand the fried dough sticks. Although a small amount of this additive will not have much impact on the body, the dosage is difficult to control and can only be manipulated by experience.
Recently, the Beijing Municipal Health Bureau conducted hygiene supervision and inspection on the breakfast sold in street stalls. However, the aluminum content in fried dough sticks and oil cakes seriously exceeded the standard, and the qualified rate was only 22.2%.
thin pancake made of flour
Cost:
Many people waiting for the bus at work have no time to have breakfast at home or at work, so in order to save time and trouble, they all buy pancakes at the station. However, some illegal hawkers use black gutter oil and excessive lemon yellow pigment. Therefore, it is best not to buy pancake stalls without health permits on the street.
Expert: There will be impurities in waste oil after refining, and it will be contaminated with toxic substances such as aflatoxin and benzene. Long-term consumption will cause chronic diseases such as tumors, such as stomach tumors and liver tumors. I don't know how many ways money will spread in the process of circulation, especially hepatitis B virus, dysentery virus and other viruses, and hands will be directly infected with bacteria. Therefore, if food in hand and money in hand are not separated, the possibility of virus infection through money will greatly increase, especially enteritis, dysentery and hepatitis, and it is easy to cause acute diseases, such as food poisoning and enteritis. So be sure to buy breakfast at those early stalls that can really pay separately.
7. Baked sweet potato
Cost:
Nowadays, people are no longer keen on the diet of big fish and big meat, but hot and delicious baked sweet potatoes have become some people's favorite snacks. I believe that most people who like baked sweet potatoes rarely ask about the source of the baking bucket. You know, the barrel of baked sweet potatoes has been smoked and cooked, and the whole body of the baked barrel has turned black, and the original words on the barrel wall are simply unrecognizable. In fact, most of these "unidentified" barrels come from garbage collection stations, and vendors use them to simply clean and modify and bake sweet potatoes. When baking, the residue in the barrel will enter the sweet potato, and even if it is peeled and eaten, it can't completely avoid its harm. If benzene is contained again, the respiratory tract and nervous system will be damaged and people will feel dizzy after eating it. There are also some vendors who bake sweet potatoes contaminated by black spot bacteria in a baking bucket, but on cooked sweet potatoes, the original obvious black spots are difficult to distinguish. Acute poisoning symptoms such as vomiting and diarrhea will appear after eating, and long-term consumption will also lead to liver damage.
8. Seafood food stall
Cost:
Some people may think that seafood that has not been heated or cooked at high temperature will not lose its nutrients, and natural seafood is the best. You can eat it raw as long as you dip it in mustard. Actually, it is not. He Jiguo, an expert in nutrition and food safety, told us that vegetables and fruits are best eaten raw, but seafood is best not eaten raw. There are many pathogenic bacteria and parasites hidden in all kinds of fresh seafood. If they are not disinfected at high temperature, they are easily infected with diseases. In addition, if protein and other nutrients in seafood are not cooked, it is not easy for people to digest after eating, and it is not conducive to human absorption. Therefore, eating seafood and other foods must be fresh and pollution-free, and it is best to cook them thoroughly. Don't damage your health by eating delicious food.
9. Fried chicken wings
Cost:
Because fried chicken wings are difficult to distinguish, be careful of the smelly chicken wings sold to you by some street stalls. In addition, although fried food tastes delicious, it stays in the stomach for a long time and is not easy to digest and absorb. In addition, alum or alum potassium is often added as a leavening agent in the production of fried foods, both of which contain aluminum. Aluminum is an amphoteric element, which means that aluminum can react with acids and bases. The compounds formed after the reaction are easily absorbed by the intestine and can enter the brain, thus affecting children's intellectual development. Fried food also contains a variety of carcinogens. One of the more powerful ones is called acrylamide. It is mainly produced in high-temperature fried food, which has a certain stimulating effect on eyes and skin, can be absorbed through skin, respiratory tract and digestive tract, and partly accumulates in the body, mainly affecting the nervous system.
10. steamed bread
Cost:
Steamed buns have a long history, and there are also many brand stores and local characteristics, such as Goubuli and soup dumplings, which are loved by the public. However, the buns sold at the street buns stand are another matter. Recently, we learned that some vendors made a big fuss about steamed buns. The meat steamed buns they made had the following four hidden dangers: First, some vendors used "blood neck meat" to make steamed buns. "Blood neck meat" refers to the meat connecting the head and body parts of pigs, which contains lymph nodes, lipomas, thyroid gland and so on. This kind of meat is cheap, but its quality is poor, and it will accumulate a lot of germs and viruses. It is not easy to kill it by heating for a short time, and it is easy to get sick after eating it. Second, the meat stuffing is mixed with stale vegetables. Third, use more lard to make steamed buns smell better. Fourthly, once the raw materials of the stuffing are a little deteriorated, as long as they are not too serious, more seasoning and salt will be added to cover up the smell of the stale raw materials.
