Diseases of fish. Their impact on human
What if the hook caught the fish with signs of disease? What threat comes from it, if the fisherman was holding it in his hands?
First of all, no panic. The majority of fish diseases to man is not transmitted. For humans, only a few diseases and on the body of the underwater inhabitants are not shown.
Fish disease manifesting on the skin
Rubella. Has following symptoms: swollen abdomen, bulging eyes, scales bristling. The disease is caused by viruses that are harmless to humans. Ill carp. If the sick fish has passed the heat treatment, then use it in the food. But it’s better to throw it away.
Fish pox. Fish covered with plaques similar to paraffin. The disease develops because of a lack of calcium in the water as well as pollution of the reservoir. Cheer carp, bream, tench and carp. To eat can, pre-flashing plaque.
Fish lice. Amazed carps, grass carps, trout and others. These lice are not insects. The so-called parasitic crustaceans. They attack fish, pierce the skin and suck blood. The venom of these crustaceans poisons fish. They become lethargic. If the number of crustaceans on the fish to twenty, to use it for food, you can, if more, better to burn.
Round and flat worms
Their scientific name worms. Pink-red worms, length to 15 cm Larvae worms pierce the intestinal wall of the fish, fall into the abdominal cavity and grow there. Infected fish much thinner, becomes inactive. If the lesion is mild, eat can. By the way, the stores often sell the affected helminths of fish, often carp. The buyers even do not suspect.
Often people do not even know what was eaten along with the fish embryo tape-worms. We are talking about flat worm that lives in the human small bowel. Man begins to lose weight dramatically, he develops anemia, poisoning the entire body.
There are small worms, not more than 10 mm, but they can seriously damage the human body. It is not excluded fatal. That’s why all caught or bought fish needs to be very carefully boil and fry.
Like all organisms on earth, fish can be a variety of tumours, both benign and malignant.
Tumors in fish are caused because of water pollution is industrial waste, pesticides. Usually fish affected benign tumors. But in the case of fish feeding spoiled feeds or even appear artificial and malignant tumors.
Can viral and bacterial diseases transmitted from fish to person? Scientific evidence that these diseases can be dangerous to humans, no.
It would be a mistake to assume that science knows everything about the vectors of fish and human. There is still much unknown. So if something caught the fish seemed suspicious, better not risk it and throw it away. Similar rules hold pickers: there are doubts, it is better to throw it away.
