According to reports, the health sector are warning consumers to beware of nitrite poisoning.

"Nitrite poisoning phenomena are not uncommon, in Guangzhou, mostly belonging to the fragmented nature of food poisoning or accidentally swallowing the industrial salt. "Wong said, nitrite is a white powder, mainly for the chemical or industrial purposes, once packed in containers not annotated, very likely to be eating; also, a lot of food poisoning are because in a short time a nitrite intake with a high level of food or meat products.

The "principle of nitrite poisoning is that it will enter the body and hemoglobin, allowing normal ferrous is oxidized to form a trivalent iron, iron and hemoglobin.

While high hemoglobin can inhibit normal hemoglobin and carries oxygen and release oxygen, leaving the body tissue hypoxia, hypoxic, particularly the central nervous system, in severe cases may be lethal. "Introduction to Rosanna, nitrite toxicity is large, the human body weight to calculate it, a person weighing 60kg, simply 1.32 g can be lethal.

Restaurants meat dishes or be placed nitrite "make-up"

It was a bit reluctant to disclose the name of the medical staff did not know whether the disclosure, the community, their own home fried attention meat, no matter how Cook, beef cooked will render natural Brown, pork loin is gray.

"He said, Chef craft did have high, but in any case, are not going to change the color of the meat.

In addition, it is understood that the leafy vegetables such as cabbage, leek, celery, beetroot, lettuce leaves, all contain a lot of nitrite, when these vegetable storage for a long time to start to rot, nitrite content will significantly increase.

The heavier the vegetable decayed subnitrate increases the more obvious; new pickled vegetables, pickled 2 ~ 4 days after the nitrite, 7 ~ 8 days to reach the most high; cooked dishes after cooking in the dirty containers for too long, in the role of nitrate-reducing bacteria, nitrates in vegetables will be restored into nitrite.
