2. disinfection with potassium permanganate: soaking live loach in 3 ~ 5 ppm potassium permanganate 10 minute before feeding can also achieve very good results. However, potassium permanganate is a strong oxidant, and the dosage must be controlled well. Just put 3 to 5 milligrams in a liter of water, and the color of the water is light purple.
3, salt disinfection: you can use five thousandths of salt solution to soak disinfection, although it also has an effect, but it is not very effective for viruses and bacteria.
Matters needing attention in eating loach
Although loach has high nutritional value, it can only be eaten fresh. Dead loach must not be eaten, because the protein structure of loach contains histidine. Once the Misgurnus anguillicaudatus dies, the protein in the body is rapidly decomposed, which leads to bacteria taking advantage of it and histidine rapidly converting into histamine. Histamine is a toxic substance. People will have dizziness, headache, palpitation, chest tightness and other uncomfortable symptoms.
Misgurnus anguillicaudatus and Monopterus albus are common freshwater fish in rice fields, which means that the living environment of Misgurnus anguillicaudatus is muddy. Misgurnus anguillicaudatus who grew up in this unsanitary environment is not safe by nature and is not suitable for raw food because of its great health problems.
