Every time this season, a large number of barbecue stalls emerge from the streets around various communities in Dalian, some of which are derived from the original indoor shops, and some are brought up out of thin air, one by one, in several major locations. Called spectacular. You have to admit that many consumers are very brave and dare to buy anything! Generally, roadside barbecues have the following food safety hazards and have to be prevented:

　　1. Open fire barbecue Food produces a large amount of carcinogens-polycyclic aromatic hydrocarbons. Polycyclic aromatic hydrocarbons are the earliest known, most important, and largest number of chemical carcinogens, including more than 400 compounds that have carcinogenic effects. The component is benzo(a)pyrene. Benzo (a) pyrene can enter the digestive tract either through the barbecue or through the smoke of the barbecue. Benzo (a) pyrene is a highly active carcinogen. After entering the body and converted into epoxide, it has a clear carcinogenic effect, which can cause many experimental animals including digestive tract cancer (such as liver cancer, esophageal cancer and gastric cancer, etc.) Kind of cancer. In addition, benzo (a) pyrene is also a definite teratogen and mutagen, with certain chronic toxicity.

　　 2. Smoked roasted meat also produces carcinogens-heterocyclic amines. The amino group on the heterocyclic amine ring is metabolized in the body into N-hydroxy compounds, which have carcinogenic and mutagenic effects. In animal experiments can cause a variety of cancers such as breast cancer, colon cancer.

　　3. Because there is no water, the meat or other ingredients (before eating) and the tableware have not been carefully washed at all, let alone disinfection, let alone bacterial contamination.

　　 4. Many stalls use nitrite to soak lamb, etc., the purpose is to make the meat color bright, good taste, but also antiseptic preservation. However, a large intake of nitrite can cause acute food poisoning-intestinal cyanosis (with hypoxia as the main symptom); regular small intake of nitrite has the potential to cause cancer-nitrite is easy in the stomach Synthesis of N-nitroso compounds, the latter has carcinogenic effects.

　　 5. Some barbecue stalls are not good enough, and they will soak the pork (even horse meat, cat meat, etc.) with lamb oil, and add condiments like "lamb flavor" to pretend to be lamb. , Its taste is said to be not bad at all.

　　 6. Barbecue stalls are smoky and pollute the air environment.

　　7. Barbecue stalls are mostly concentrated around the station or community, where life is noisy and disturbing people.

　　As far as I know, in the past, the urban management departments of many cities (including Dalian) regularly cleaned up such barbecue stalls (mostly undocumented or illegally occupied roads). In recent years, governments at all levels Pay special attention to the image of the people, and no longer strictly manage such barbecue stalls. Consumers must take their own weight!
