The following year, a random check confirmed that such a focus of the disease existed in roaches. It is not so much the fish itself that is dangerous - it is a carrier of a severe pathogen, and its “definitive hosts” are mammals that become infected by eating fish. It is they who are overtaken by a dangerous, including for humans, intractable disease that affects the liver, gallbladder, pancreas, etc.
This time again, the Leningrad Region Veterinary Service tried to take measures to ensure that no one was in danger: it banned the sale of fresh fish. I recommended freezing the “risky” roach for several days, after which the vital activity of the larvae ceases and the fish can be placed on a cutting board. Experts advised that it should be boiled or fried for at least 20 minutes, and dried for three weeks, no less. However, one could only guess about the features and scale of the alarming process itself: there was not enough data.
Laboratory tests this year dispelled doubts: yes, serious large-scale studies are needed, commissioned by the relevant structures of the Leningrad region government. This was also confirmed by a more thorough check carried out by St. Petersburg scientists.
Although in the bay near Strelna and Sestroretsk, as well as in other areas that are examined by specialists from the State Research Institute of Lake and River Fisheries named after. L. S. Berg (GosNIORH), the situation turned out to be different: no pathogens were found there.
Although it is possible that the culprit is pathogens that entered the bay with sewage during the construction of the Nord Stream 1 gas pipeline. Hundreds of workers who arrived from other regions (including those who ended up in the “opisthorchiasis” zone) of workers were involved there. This option also cannot be discounted, scientists believe.
In any case, a certain version can only be confirmed or refuted by thorough scientific work lasting several years, which would include “clear” system monitoring, studies of marine mammals, drawing up a map of dangerous areas of the bay, etc. And for the implementation of the entire range of measures and control This disease requires a science-based program that rests on a strong financial foundation.
You can become infected with opisthorchiasis by eating fresh or freshly salted fish. If a roach, even an infected one, is thoroughly cooked on both sides, there is no danger to humans. It is advisable to cook dried fish for a couple of weeks and spare no salt. If we were talking about a disease outbreak, all services would be aware of the matter. And traders of dried and fresh roach would be immediately removed from the streets of Vyborg. Maybe they just want citizens to buy more expensive fish? - the specialist suggests.
Indeed, all kinds of fish, including roach, can be bought without problems. Dried milk is sold by old women in the city center or in the Southern village. There, in the village, along with smelt, fresh roach, supposedly caught in Lake Ladoga, is also offered.
It is characteristic that the majority of Internet users also believe that the panic is greatly exaggerated. Here are just a few reviews: “Amazing! So, does everyone eat raw?!”, “This announcement was made last year! Everyone dried it, ate it, no one got poisoned,” “It’s easier to eat dumplings from the store.” But one of the participants in the discussion does not exclude the seriousness of the situation and gives practical advice: “Guys, you shouldn’t be doing this, although this is anomalous for our area! It is better to disinfect by salting 1.5 packs of salt per 10-liter bucket of fish or thermal bath for 20 minutes. Think! And then don’t refer to hepatitis and pancreatitis!”
