No. 64

, feed production enterprises suspended the use of pig blood-based blood products for the production of pig feed.December 28, 2018, the Ministry of Agriculture and Rural Affairs issued
91 notice

, eligible pig blood products were released.January 15, 2019, the head of the Animal husbandry and veterinary department of the Ministry of Agriculture and Rural Affairs gave a detailed answer on the reasons why pig blood products were first banned and then banned.small editor combed, summarized the official reasons for the release of pig blood products have the following eight points:
1, pig blood products testing nucleic acid positive does not mean that the products produced through the standardized process contains live viruses;2, has now identified the source of the epidemic of all domestic pigs outbreak, did not find the spread of commercial feed containing pig blood raw materials in Africa swine fever epidemic;3, the United States, Canada and the European Union and most other countries and regions are allowed to pig blood protein powder and other feeding blood products used in pig feed;4, plasma protein powder products can provide an effective technical solution for 2020 after the withdrawal of growth-promoting antibiotics.5, each year to produce more than 2 million tons of pig blood, can produce 400,000 tons of pig blood products, the lifting of the ban not only can reduce the cost of slaughtering enterprises for pig blood by-products to find a way out, 6, pig blood protein content is rich, generally 16%-18%, this can alleviate the shortage of protein resources in China;7, the concentrated production of pig blood products can reduce the random emissions of environmental pollution;8, high temperature spray drying process can effectively spread the risk of epidemic through blood.asked: Pig blood protein powder and other feeding blood products to spread the african swine plague virus, whether a scientific assessment?A: Feeding blood products refers to the slaughter of pigs and other livestock and poultry to obtain fresh blood as raw materials, after sterilization, separation, drying and a series of processing products, including plasma protein powder, hematocypnoprotein powder and blood powder three categories.since August 2018, the Ministry of Agriculture and Rural Affairs has conducted a comprehensive sampling of the products of all feed blood products manufacturers and found that individual batches of products have tested positive for African swine fever nucleic acid. However, testing positive for nucleic aciddoes not mean that a product produced by a standardized process contains a live virus. The Spanish Institute of Food Science and Technology conducted an inactivated test of the African swine fever virus, which treated pig plasma with high concentrations of live virus by spray drying, and the results showed a virus inactivation rate of more than 99.99%.to prevent the spread of swine fever in Africa, the Ministry of Agriculture and Rural Affairs issued a notice on September 13, 2018 to suspend the use of forage blood products produced from pig blood as raw materials in pig feed. At the same time, in order to assess the risk of transmission of nucleic acid-positive blood products for scientific systems, the Ministry of Agriculture and Rural Affairs arranged for the China Center for Animal Health and Epidemiology and the Harbin Veterinary Research Institute of the Chinese Academy of Agricultural Sciences to conduct the virus activity test and animal feeding tests of nucleic acid-positive pig hemoglobin powder. The results showed that the samples of nucleic acid-positive for the African swine fever virus were not viralally active, no symptoms of viral infection were found after feeding piglets, and no African swine fever virus was detected in the blood. From the epidemiological investigation, the whole domestic pig outbreak has been identified as the source of the epidemic, no commercial feed containing pig blood raw materials caused by the spread of african swine fever epidemic.ask: What is the use of blood products such as pig blood protein powder in developed countries abroad?: Most countries and regions, such as the United States, Canada and the European Union, allow pig blood protein powder and other feeding products to be used in pig feed. In October 2014, the World Organization for Animal Health (OIE) confirmed that blood products such as pig plasma protein powder are not a possible source of infection for viruses such as the pig-prevalence diarrhea virus, if good production practices and bio-safety standards are in good condition. the European Union countries due to the occurrence of foot-and-mouth disease, infectious spongiform encephalopathy ("mad cow disease"), feed dioxin pollution and other crisis events, the inappropriate use of certain animal by-products may cause harm to human and animal health, in 2001 banned the use of animal and poultry blood products for feed. However, in 2006 regulations were introduced to allow non-ruminant blood products such as pigs to be used in feed. at present, the United States and Canada plasma protein powder production of about 25,000 tons, the European Union annual output of about 15,000 tons, most of the pig-breeding tank material in the proportion of 2%-5% added to the use, with China's use of methods, the proportion and use of similar. ask: What specific measures has the Ministry of Agriculture and Rural Affairs put in place on the risk of strictly preventing and controlling the spread of African swine fever virus from feed products? : After the relevant tests and evaluation, the use of high-temperature spray drying process produced pig blood protein powder, even if the test results are positive for the African swine fever virus nucleic acid, the risk of transmission of the outbreak is very low. However, in order to strengthen risk control, the Ministry of Agriculture and Rural Affairs issued a notice No. 91 on December 28, 2018, which introduced strict process control measures for all aspects of pig blood protein powder production. in the slaughtering link, clearly require enterprises to strengthen the detection of african swine plague virus in pig blood, effectively put good pig blood raw materials safe, improve pig blood collection and storage conditions, the implementation of closed transport and storage. Factory should be equipped with vehicle disinfection facilities, into the factory pig blood transport vehicles disinfection. In the production link, clearly require sage blood products production enterprises to good raw materials, technology and finished products factory clearance, strict implementation of raw materials into the factory inspection system, pig blood raw materials must come from the slaughterhouse (point) without the african swine plague outbreak, pig blood source of the same batch of pigs need to pass the slaughterhouse (farm) African swine plague testing, the raw materials into the factory transport vehicles disinfection, strict implementation of production, sample observation and sales record system. Product production must adopt high-temperature spray drying process, spray drying equipment air temperature is not less than 220 degrees C, air temperature is not less than 80 degrees C, spray drying materials to be more than 60 degrees C to maintain more than 20 minutes. The finished product must be stored in the finished product warehouse (room temperature is maintained at room temperature above 20 degrees C) for more than 20 days, and passed the African swine plague test before it can be sold out of the factory. At the same time, pig blood raw materials and finished products to implement strict physical isolation, control the flow of personnel and materials, strictly prevent pollution. At the same time, also formulated the "pig blood as raw materials for feeding blood products production enterprise facilities and environmental disinfection norms", requiring enterprises to carry out the relevant disinfection work in strict accordance with the norms. Ask: Allow pig blood protein powder and other feeding blood products to be used in feed, in addition to systematic assessment of the risk of transmission of the virus is very low, what other considerations? : This is a careful decision made after the relevant trials and risk assessments, taking into account a number of factors and taking into account international experience. On the one hand, considering that plasma protein powder products play a role in enhancing piglet immunity and reducing diarrhea and other health problems, it can provide effective technical solutions for 2020 after the withdrawal of the growing antibiotics. On the other hand, we should also give full consideration to finding a way out for the slaughter of pig blood by-products, effectively reducing the risk of environmental pollution and epidemic transmission caused by random emissions. China's annual column of nearly 700 million pigs, pig blood annual production of more than 2 million tons. Pig blood has high nutrient content, rich bioactive substances, protein content is generally 16%-18%, containing a variety of mineral elements, vitamins, amino acids and immunoglobulins. Tested qualified pig blood by high temperature spray drying process treatment, per ton of pig blood can produce plasma protein powder 50 kg and hemoprotein powder 150 kg, can be used as high-quality feed raw materials. if the use of pig blood by-products feed is prohibited, it will cause additional cost expenses to slaughter enterprises, which may cause the random discharge of pig blood, which poses a great risk of environmental pollution. In addition, because of the rich nutrition of pig blood, is a good carrier of pathogenic microorganisms and culture matrix, in natural conditions easy to breed germs, breeding viruses, there is a greater risk of disease transmission. in the current critical period of swine plague prevention and control in Africa, allowing production enterprises to use slaughtered pig blood, through high-temperature spray drying process processing into pig plasma protein powder and hemoglobin powder, sales to feed enterprises as raw materials for the production of commercial pig feed, can be slaughtered to find a way out of pig blood by-products, not only to alleviate the shortage of protein feed resources in China, but also effectively avoid the risk of spreading the epidemic through blood channels. ask: How can the Ministry of Agriculture and Rural Affairs ensure that control measures are put in place? : Next, the Ministry of Agriculture and Rural Affairs will require local authorities at all levels to strengthen the supervision and management of the production of blood products for feeding, to conduct a comprehensive on-site inspection of all enterprises within the jurisdiction, enterprises that meet the requirements of the announcement can continue to produce and sell, crack down on unlicensed production practices, and resolutely prohibit the production process of drying and other backward production processes. For enterprises whose control measures are not in place, it is ordered to stop production immediately, to rectify within a time limit, and to resume production only after on-site verification and rectification is in place; Ensure that nothing is lost through the implementation of strict and comprehensive controls. At the same time, the Ministry of Agriculture and Rural Affairs will strengthen supervision and inspection of local management departments to ensure that control measures are put in place. (
