Factors affecting feed safety and control measures
Feed safety refers to the characteristics that feed products will not have a negative impact on animal health, normal growth, sustainable development of ecological environment, human health and life in the process of production, processing, transportation and animal transformation into animal products.
Characteristics of feed safety issues
Concealed
The concealment of feed safety is that under normal circumstances, the use of feed can not directly reflect or express the hazard. On the contrary, sometimes the growth rate of the animals to be fed will increase, and the rate of goods will increase, but the factors of insecurity are It will be transferred to the human body through animal products, causing harm to human health; it will also be discharged to the environment through the excrement, which in turn will cause harm to human health. Therefore, feed safety issues are hidden.
Cumulative
Unsafe factors in the feed, such as heavy metals and toxic and harmful substances, will accumulate through the products or organs of the animals being fed. After eating these animal products or organs, people will affect human health and even cause poisoning or death. Second, they will pass excretion. The material is discharged to the outside environment to pollute the surrounding environment, thereby polluting the water source, causing harm to human health.
Complexity
The number of factors that contribute to feed safety issues is large and variable, which determines the complexity of feed safety issues. Such as industrial pollution, pesticide pollution, improper storage of feed ingredients, mildew, improper use of feed additives, etc. will cause feed safety problems.
Long-term
Due to the concealment of feed insecurity, toxic and hazardous substances can accumulate in the environment, and the factors that cause feed insecurity are complex and variable, which makes people unable to solve these problems in a short period of time and determines the long-term problem of feed safety.
Factors affecting feed safety
Factors affecting feed safety include both human factors and natural factors. Human factors mainly refer to the purpose of adding certain harmful drugs to the feed in order to achieve certain purposes (such as promoting the growth of animals or preventing diseases). Natural factors mainly refer to the harmful substances in the feed ingredients due to natural chemical factors or environmental pollution caused by industry and agriculture, as well as the harmful substances naturally present in the raw materials.
Human factors
Abuse of illegal drugs or improper use of pharmaceutical additives. The Ministry of Agriculture issued the "Guidelines for the Use of Feed Drug Additives" in September 2001, which stipulated the applicable animals, usage and dosage, drug withdrawal period, precautions, etc. of 33 kinds of feed pharmaceutical additives. And 24 feed drug additives that cannot be added to the feed. In February 2002, the Ministry of Agriculture, the Ministry of Health, and the State Drug Administration issued a joint announcement, promulgating the Catalogue of Drugs Banned for Use in Feed and Animal Drinking Water, with a total of 40 categories in 5 categories. It is emphasized that it is strictly forbidden to add feed pharmaceutical additives that have not been approved for use by the Ministry of Agriculture. However, in actual production, some feed mills are not implemented as required, and some banned feed pharmaceutical additives are still being used. Animal breeding relies too much on drugs such as antibiotics, which causes many problems. For example, animal feeding with antibiotics leads to drug residues, causing the spread of drug-resistant strains, causing serious harm to animals, people and the ecological environment, causing dysbacteriosis of animal flora and inhibiting animal immunity. Force, secondary secondary infection. A large number of drugs used at the same time are absorbed by the body through the food chain, causing carcinogenic, teratogenic, and mutagenic effects.
