The weather is getting hotter, about three or five friends in the evening, order a plate of fried snails, drink a few bottles of beer, not only delicious, but also chat and laugh while eating, that feeling, cool! But, are you eating Sanada snails?
Is there a fake field snail? Yes, there are indeed some restaurants and food stalls that use Freshwater snails that are very close in shape but much cheaper in appearance to Pass off. Being slaughtered is still a trivial matter, and what is more deadly is that Fushou snail and brown cloud agate snail are the disease media of pathogens and parasites such as Guangzhou tube roundworm. As early as 2006, a number of diners ate cold snail meat at the Shuguo Yanyi Restaurant in Beijing, and were later diagnosed with eosinophilia meningitis (that is, Guangzhou tube roundworm disease), which can cause dementia and even death, and the snail meat of this store is made of Fushou snail.
Field snail, Fushou snail, brown cloud agate snail, silly and unclear? No, today I will introduce the difference between the three, a little attention, at a glance can distinguish them, in the future to eat fried field snails will no longer be deceived!
Guess what this stir-fry is a field snail?
<h1>Field snail PK Fushou snail</h1>
Fushou snail's hometown is in the Amazon River Valley in South America, and was introduced to Guangdong as a food in the 1980s, but due to its hard meat quality and poor taste, few people soon raised it again. But at this time, a large number of Fushou snails are released into the wild, adapting to the environment and having a strong ability to survive and reproduce quickly, so they quickly spread to rivers, lakes and fields.
Is the "egg" under the Fushou snail cute?
Now, we often see bunches of pink "small grapes" on the banks of urban river walls, which are likely to be the eggs of Fushou snails. Fushou snail is the most used to impersonate a field snail, because its appearance is closest to the field snail, the production is large, and the price is less than half of the field snail. However, Fushou snail is the intermediate host of Guangzhou tube roundworm, and experts and professors from South China Agricultural University introduced that each Fushou snail contains as many as 3,000 to 6,000 Guangzhou pipe roundline larvae. If you eat raw or eat undercooked Fushou snail, nematodes can easily invade the human body, especially destroying nerve tissue.
So, how to distinguish between field snail and Fushou snail? From the appearance point of view, most of the snails are 1-1.5 cm long, and the Fushou snails are relatively larger. The shell color of the Fushou snail is yellow, the shell is smoother, and the shell color of the field snail is bluish brown. The "ass" of the Fushou snail is flat and short, and the "ass" of the field snail is long and pointed. The fushou snail cover is flattened, and the shape of the snail cover is relatively rounded. The flesh of Fushou snail is lighter in color, mostly yellowish-white, while the flesh of the field snail is mostly bluish brown.
Judging from the feel, the shell of the Fushou snail is very brittle, and it can be easily kneaded and exploded by hand. The shell of the field snail is hard, not only can not be broken, but it is also difficult to pinch and explode by hand.
<h1>Field snail PK brown cloud agate snail</h1>
The brown cloud onyx snail is a new li ghost that has just emerged in recent years, and it is said that unscrupulous traders use it to impersonate a conch. In fact, this is not a snail, but a land snail, the real name is the African snail, it will also be called dew snail, Dongfeng snail, vegetable snail.
This guy originated in eastern Africa, and legend has it that when Xiamen University was founded in 1921, some plant species were introduced from Nanyang, and the African giant snail hidden in the roots of the plant was inadvertently brought into Xiamen. African large snail breeding speed is extremely fast, hermaphrodite, allogeneic mating, a single spawn number of 100-400 pieces, and has a ferocious feeding, rapid growth, strong reproductive ability and other biological characteristics, can harm more than 500 crops, known as the "pastoral killer" in the world. At present, African large snails have been found in the wild in Fujian, Guangdong, Guangxi and other places.
The African giant snail is an intermediate host for a wide range of human and animal parasites and pathogenic bacteria, especially for the transmission of tuberculosis and eosinophilic meningitis, especially eosinophilic meningitis, and there is no good treatment. In addition, the vegetables and fruits they crawl through may remain the source of the disease, thus invading the human body. For this dangerous species, it is best not to eat it. If consumed, it must be cooked at least at a high temperature of more than 80 ° C.
African snail oh
Compared to the Fushou snail, the African snail is very recognizable because it is big! This guy is usually 7-8 cm long, up to 20 cm, and the same as a child's fist. Its shell "ass" is pointed and the sutures are deep. The shell surface is yellow or dark yellow with a burnt brown mist pattern.
A bunch of big African snails
<h1>At last</h1>
Even Sanada snails, for reasons such as water quality, can carry parasites and bacteria. The snail should be soaked in clean water for a few days in order to allow the snail to fully discharge the dirty substances, and when cooking the snail, be sure to pay attention to boiling it at a high temperature for a period of time in order to completely kill the parasites and germs in the snail.
Again, all snails, including field snails, must be cooked before eating!
