Two kebabs of mutton
The roasted meat will give off fragrance and be very delicious, which is the most delicious food in all cooking methods. This is because the barbecue evaporates the water and makes the taste concentrated, which is far better than the light and tasteless boiled meat. However, the mutton skewers are "hidden and murderous". In order to save costs, some black-hearted bosses buy back dead cat meat or duck meat at a very low price, soak them in a basin filled with sheep urine for a few hours, then marinate them with tender meat powder and various seasonings for 2 to 3 minutes, and then add some sheep oil when slicing them with a skewer, and add some "mutton essence" to the seasoning when they go to the oven. After such "meticulous work" and high-temperature fumigation, it has become a serious cottage "mutton kebab".
Three-fried dough sticks cake
Salt, alkali and alum are the three raw materials for fried dough sticks. Some black-hearted bosses add more alum to make the dough sticks fluffy and crisp, even if they are kept for a few hours, which leads to excessive aluminum content in the dough sticks. Although aluminum is a low-toxic metal element, long-term and excessive intake will accumulate in the body, which will affect brain thinking and damage vision and motor coordination. Especially for the elderly, children and pregnant women. In addition, the excessive aluminum residue in fritters is also related to the use time of oil and the number of turns. Repeated use of edible oil will produce "free radicals", which will lead to premature aging, damage the liver, digestive tract, stomach and intestine, and even cause cancer.
Four seafood stalls
Seafood stalls have a broad market in coastal cities, and many tourists take it as an important experience activity when they go to the seaside for vacation. However, the sanitary conditions of seafood stalls on the street are mostly poor, and unclean seafood products are easy to cause intestinal diseases if eaten. Some unscrupulous traders even soak seafood with formaldehyde (formalin) in order to prevent it from rotting and stinking, and the residual toxins of these formaldehyde-soaked seafood products and water-soaked products can harm human liver. If the human body inhales low-concentration formaldehyde for a long time, it will produce symptoms such as loss of appetite, headache, insomnia and weakness, finger tremor, vision loss, and affect liver and kidney function; Inhalation of high concentration of formaldehyde will cause mucosal necrosis and pneumonia, and even throat edema and spasm and suffocation, and as long as 1 ~ 2 ml is ingested, it can be fatal.
