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.

The so-called "Chenhua Food" refers to food that has been stored in the grain store for more than one year, and its quality has been seriously reduced or deteriorated. "Chenhualiang" has exceeded the standard for mold, and the state strictly prohibits it from directly serving as a ration, and it can only be sold to brewing, feed, and other large industrial grain producers through auctions. Then, can the “Chen Hualiang†with excessive mold levels produce feed for raising livestock and poultry? In recent years, many farmers in our province have reported that although the feed formulation and raw materials have not changed, the effects of keeping livestock and poultry are very different. In terms of pigs, the occurrence of spurious estrus in the gilts, swelling in the genitals, and rectal valgus; long-term infertility in sows, increased miscarriage rate in pregnant sows; vomiting, reduced feed intake, slow growth, and reduced feed conversion rate in pigs producing finishing pigs The quality of boar semen decreased. In terms of poultry, the production of poultry eggs becomes smaller, the eggshell is brittle, the color becomes shallower, the egg production rate is decreased, the hatching rate of the breeding eggs is low, the young birds develop stomatitis, and the growth is hindered. Through testing, the culprit is caused by mycotoxins. The main toxins are aflatoxin, T-2 toxin, vomitoxin, zearalenone, ochratoxin and fumonisin. These mycotoxins were detected mainly from mouldy corn, moldy wheat bran, and aged grains, and were detected in the full-price compound feeds used by livestock and poultry. Moldy corn, moldy wheat bran, and aging grain have a great impact on the health and growth performance of livestock and poultry. Among them, aflatoxin can be transferred to milk, eggs, livestock and poultry's internal organs and muscles after being eaten by livestock and poultry. People who eat foods containing low concentrations of aflatoxin for a long time are important factors in inducing liver cancer, gastric cancer, and colorectal cancer. Farmers should be cautious about converting “Chenhualiang†to “feed grainâ€, and pay attention to the following points in the process of feed production and use: 1. Obviously mildewed feedstuffs must not be used for feed production; 2. Invisible to the naked eye The mildewed raw materials must be tested for mycotoxin during the procurement. For example, toxins can not be used for feed production. 3. Although mycotoxins are detected in the raw materials, they do not exceed the standard. Toxic toxin adsorbents should be added during the production of feeds. Reduce or eliminate the effects of mycotoxins; 4. Procurement of raw materials that have just been listed on the market is prone to mold growth due to excessive moisture content. It should not be stored for a long time and should be used up as soon as possible. 5. Feed or dry feed warehouses should be kept ventilated and dry; The storage period of the finished product feed should not be too long, and the feed should be used up within a very short time after unpacking.
