This standard is applicable to all kinds of livestock and poultry farms, meat processing plants, designated slaughtering points, livestock and poultry transportation and meat markets, etc. 2 Objects to be treated
2.1 Carcasses (excluding fur, viscera and hooves) and their products (viscera, blood, bones, hooves, horns and fur) of pigs, cattle, sheep, horses, donkeys, pheasants, camels, rabbits, chickens, turkeys, ducks and geese with infectious diseases, parasitic diseases and poisonous diseases. 2.2 The harmless disposal of other diseased animals and their products shall refer to this standard. 3.3.1.1.1.3.3.3.3.4 ... , porcine treponemal disease, acute swine erysipelas, bovine rhinotracheitis, mucosal diseases, leptospirosis (yellow-stained carcasses), listeriosis, brucellosis, Newcastle disease, Marek's disease, fowl plague (avian influenza), goose plague, duck plague, rabbit viral hemorrhagic disease, rabbit fever, rabbit Clostridium perfringens disease and other infectious diseases and malignant tumors or tumors in two organs of sick livestock and poultry whole carcasses; diseased parts and viscera cut off from other sick livestock and poultry. 3.1.2 Operation method
In the following operations, the body should be transported in a sealed container. 3.1.2.1 Wet chemical
Use a humidifier to put the whole body into chemical processing (boiling industrial oil). 3.1.2.2 Destruction
Put the whole body or the cut diseased parts and viscera into an incinerator for burning and carbonization. 3.2 Chemical Processing
3.2.1 Applicable Objects
All livestock and poultry with serious lesions and muscle degeneration, except for those in 3.1.1, infected with other infectious diseases, poisonous diseases, cysticercosis, trichinosis, and the whole carcasses or meat and viscera of livestock and poultry that died of their own accord or for unknown reasons. 3.2.2 Operation Method
Use a dryer to classify the raw materials and put them into chemical processing separately. The method in 3.1.2.1 can also be used for chemical processing. Approved by the State Bureau of Technical Supervision on October 3, 1996, and implemented on February 1, 1997
3.3 High-temperature treatment
3.3.1 Applicable objects
GB 16548-1996
Carcasses and viscera of livestock and poultry infected with swine plague, hemolytic streptococcal disease, swine paratyphoid, tuberculosis, paratuberculosis, fowl cholera, infectious bursal disease, infectious bronchitis, infectious laryngotracheitis, sheep pox, arthritis encephalitis in goats, madie/visna disease in sheep, toxoplasmosis, piroplasmosis, trypanosomiasis, etc.
Livestock and poultry in the same group as livestock and poultry infected with 3.1.1 infectious diseases, as well as carcasses and viscera suspected of being contaminated by them. 3.3.2 Operation method
3.3.2.1 High-pressure cooking method
Cut the carcass into pieces of no more than 2kg and no more than 8cm thick, place them in a sealed high-pressure cooker, and cook them at a pressure of 112kPa for 1.5~2h.
3.3.2.2 General boiling method
Cut the carcass into pieces of the size specified in 3.3.2.1, place them in an ordinary pot and boil them for 2~~2.5h (starting from the time when the water boils). 4 Harmless treatment of sick animal products
4.1 Blood
4.1.1 Bleaching powder disinfection method
Used for the treatment of blood of livestock and poultry with infectious diseases and blood parasitic diseases listed in 3.1.1. Add 1 part of bleaching powder to 4 parts of blood and stir thoroughly. Leave it for 24h and then bury it in a special waste burial site. 4.1.2 High temperature treatment
Used for the treatment of blood of sick livestock and poultry in 3.3.1. Cut the coagulated blood into tofu cubes and boil them in boiling water until the deep part of the blood clots turns black and red and forms a honeycomb shape. 4.2 Hoofs, bones and horns
Put the bones of sick livestock and poultry and the hooves and horns of sick livestock removed during high temperature treatment by butchers into a pressure cooker and steam until the bones are degummed or defatted. 4.3 Fur
4.3.1 Disinfection with hydrochloric acid and salt solution
Used for disinfection of fur of animals contaminated by diseases in 3.1.1 and general sick animals. Mix 2.5% hydrochloric acid solution and 15% salt solution in equal amounts, soak the hides in this solution, and keep the liquid temperature at about 30℃ for 40 hours. The ratio of hides to disinfectant is 1:10 (m/V). After soaking, remove and drain, put into 2% sodium hydroxide solution to neutralize the acid on the skin, then rinse with water and dry. You can also prepare a disinfectant by adding 1mL of hydrochloric acid to 100mL of 25% salt water solution, soak for 48 hours at room temperature 15℃, and the ratio of skin to disinfectant is 1:4. After soaking, remove and drain, soak in 1% sodium hydroxide solution again to neutralize the acid on the skin, then rinse with water and dry. 4.3.2 Peracetic acid disinfection methodwww.bzxz.net
Used for disinfection of fur of any sick animal.
Put the fur in a freshly prepared 2% peracetic acid solution and soak for 30 minutes, remove, rinse with water and dry. 4.3.3 Alkaline salt solution immersion disinfection
Used for disinfection of fur contaminated with epidemic diseases as in 3.1.1. Immerse the diseased skin in 5% alkaline salt solution (5% caustic soda added to saturated salt water) at room temperature (17-20℃) for 24 hours, stirring at any time, then take it out and hang it up, wait for the alkaline salt solution to drain out, soak it in 5% hydrochloric acid solution to neutralize the acid and alkali on the skin, remove it, rinse it with water and dry it. 4.3.4 Lime milk immersion disinfection
Used for disinfection of foot-and-mouth disease and mite disease diseased skin. Preparation method: Add 1 part of quicklime to 1 part of water to make slaked lime, and then use water to make a 10% or 5% suspension (lime milk). For foot-and-mouth disease diseased skin, immerse the diseased skin in 10% lime milk for 2 hours; for mite disease diseased skin, immerse the skin in 5% lime milk for 12 hours, then take it out and dry it.
4.3.5 Salting disinfection
Used for disinfection of brucellosis diseased skin.
CB16548—1996
Use salt that is 15% of the weight of the skin and sprinkle it evenly on the surface of the skin. Generally, the fur is pickled for two months, and the fetal fur is pickled for three months. 4.4 Treatment of bristles of sick animals
Boil the bristles in boiling water for 2 to 2.5 hours.
Used for the treatment of bristles of any sick animals.
