For cattle infected with non-communicable diseases and mechanical trauma, timely treatment should be carried out by infectious disease doctors. Dead cattle should be treated harmlessly at the designated time and following GB 16548. Milk produced by diseased cows (such as heat stroke) should not be sold as commercial milk in the milk market. After infectious diseases occur in cattle farms, diseased cattle should be isolated in time.

How to deal with dead cattle?

At present, there are four main treatment methods for dead cows:

  1. High-temperature cooking

The corpse of dairy cows was boiled in a special high-temperature pot (150°C) to achieve the purpose of thorough disinfection.

  • Incineration method

It is used to deal with the dead cattle caused by infectious diseases that endanger the health of human beings and livestock. Generally, a cross-shaped ditch is dug, hay, firewood, and corpses are placed in order and then burned.

Effective purification measures should be taken to prevent smoke, carbon monoxide and odor from polluting the environment.

  • Deep burial method

More than three safe landfills should be set up in the farms without incineration conditions to make use of the self-purification of the soil to make it harmless. The depth of landfill well is more than 3m, the diameter is lm, and the inlet is sealed with a cover. When landfilling, a layer of hydrated lime with a thickness greater than 10 cm should be covered after each human body is thrown. After the well is filled, it must be compacted with clay and sealed.

Or choose a designated location that is dry, high-lying and far away from houses, roads, wells, rivers, and other pastures, dig deep pits to bury the bodies and cover them with a layer of lime. The length and width of the pit should accommodate the body to lie on its side, and the depth should be more than 2 m.

  • Chemical system

Dead cattle were processed at designated chemical production stations (factories). It can be mechanized by drying or wetting the whole body.

Many of the cows that died of illness died from some kind of infectious disease. Some of them are zoonotic infectious diseases, such as foot-and-mouth disease, tuberculosis and so on. Such meat is inedible. If you eat these sick and dead dairy beef and milk steak, people will easily be infected with these diseases, which is very harmful to people's health. Some livestock and poultry do not die of infectious diseases, but after death, harmful bacteria in the body will multiply and spread rapidly to the muscles. Some bacteria can also produce toxins.

If people eat this kind of dairy beef, food poisoning will occur. Some dairy cows may die from poisoning by eating feed contaminated by highly toxic pesticides. If people eat this kind of dairy beef, they may also get milk allergy or even cause death.

Besides, if the dead cows are discarded at will without taking measures, they will seriously pollute the environment and water sources, endanger human and animal health, and may even cause infectious diseases. Therefore, the dead cows must be treated harmlessly following the relevant laws and regulations of the state, and should not be disposed of at will.
