Harm of Hepatitis C
Hepatitis C is a disease transmitted primarily through blood. Chronic
infection of hepatitis C virus (HCV) can cause chronic inflammatory
necrosis and fibrosis of the liver, which may progress into hepatic
cellular cancer (HCC), extremely harmful for the patient's health and
life. Hepatitis C has become a serious social and public health problem
in the world.

Well water fish with caution potassium permanganate
Disinfection of fish with potassium permanganate can prevent and treat many fish diseases such as anchor head plague, ringworm disease, and third generation worm diseases, but potassium permanganate disinfection should be used with great care in well water fish farming areas. The iron content in the well water is relatively high, and it does not contact the air but exists as a divalent iron ion. Divalent iron ions are easily oxidized to the stable state of trivalent iron ions, eventually forming yellow-brown ferric hydroxide colloids. Potassium permanganate is a strong oxidant that can oxidize divalent iron ions to trivalent iron ions to form iron oxide precipitates. If it is disinfected with potassium permanganate, it reacts with divalent iron ions in the well water to form iron hydroxide. The iron hydroxide will precipitate a brownish film on the surimi as the fish breathes, preventing the fish from breathing and causing the fish to Suffocate death. Iron hydroxide also adsorbs on the surface of the fish, making it difficult for fish to move. In addition, the manganese dioxide produced by the reaction can be combined with protein into protein salt compounds, and high concentration of manganese dioxide has stimulatory and corrosive effects on the fish body.
