As a foodie,
But what about my favorite braised fish?

"When we buy fish, we often find that the tail of the fish has such a red color of blood, in fact, this is not blood, we use scissors to cut it open, in fact, inside is a bug, parasite, really very scary, so everyone should be careful when buying fish in the future." A video circulating online shows a man using tweezers to pull out several blood-like red threads from the tail of a fish, calling them parasites.
In order to judge whether what the man in the video said is true, the reporter came to an aquatic market in Kunming and found that some fish really have red blood on their tails, so is this a parasite?
Vendor: "As far as we know, the parasites of fish are generally in the stomach, that is, inside the fish's internal organs. ”
Vendor: "The parasites are all in the meat. ”
Vendor: "Generally parasites are parasitic in shellfish products, and fish are impossible." ”
Subsequently, the reporter purchased a fish with red blood on its tail and brought it to the Kunming Fisheries Science Research Institute. After examining it, the researchers said that the fish was a frozen fish and had been dead for a long time, so it was impossible to distinguish whether there was a parasite.
However, according to researchers, the red blood streaks drawn from the videos released by netizens are indeed parasites, called uterine-loving nematodes, which generally parasitize on the surface of freshwater fish, that is, under the tail and fish scales.
Xiao Yong, senior agronomist of Kunming Fisheries Science Research Institute: "Parasitic freshwater fish are carp and crucian carp, which are ubiquitous in them and belong to parasites on the surface of the body. Affected by water quality and friction between fish can be contagious. ”
Xiao Yong introduced that uterine nematodes are transmitted between fish and do not infect humans. Common parasites also have tongue tapeworms, if there are eggs contaminated with water fleas, after being preyed by fish, they will be brought to the fish body to hatch, so when the public buys fish, try not to choose fish with unnatural bulges in the abdomen.
Xiao Yong, senior agronomist of Kunming Fisheries Science Research Institute: "This is a common white fish, and its stomach is like noodles, which is tongue-like tapeworm, but there is no problem after cooking." ”
The two parasites described above are safe, but be careful if you see the white bug below.

It is called is anisakis, mainly in marine fish is more common, once a person is infected, there will be nausea, vomiting, diarrhea and other symptoms.
Xiao Yong introduced that there are more than 3,000 kinds of parasites found in the fish body, in addition to the xenocephalus, liver flukes, and taenia, most of the rest of the parasites will not infect humans, even if the public buys fish that can infect human parasites, just pay attention to the following points to avoid being infected.
When handling fish, the cutting board should be raw and cooked separately to avoid cross-infection;
Treat the fish offal cleanly, and try not to eat the related products of the fish offal;
Heat the fish thoroughly when eating it, and then eat it thoroughly.
