The veterinary drugs test provided by BALLYA AniFast Test can detect many veterinary drugs. Include 3 types detection methods: Colloidal gold immunochromatography, Immunofluorescence chromatography and ELISA. There are quantitative and qualitative format rapid test, easy to operate, shortern assay time, reliable detection result. The test is done using competitive ELISA (competitive ELISA). Competitive ELISA is a very sensitive detection method that uses antibodies prepared against veterinary drugs. The BALLYA AniFast test frequently use in feed and food, etc.
Main veterinary drugs that produce veterinary drug residues
Antibiotics Large and frequent use of antibiotics can make drug-resistant pathogenic bacteria in animals easily infect humans; and antibiotic drug residues can cause bacteria in humans to develop drug resistance, disturb the human micro-ecology and produce various toxic side effects. The antibiotics that are likely to cause excessive residues in animal products are mainly chloramphenicol, tetracycline, oxytetracycline, and chloramphenicol.
Sulfonamides Sulfonamide drugs remain in animal-derived foods mainly through infusion, oral, external use for trauma, or as feed additives. In the past 15 to 20 years, the excess of sulfonamide residues in animal-derived foods has been very serious, mostly in pigs, poultry, cattle and other animals.
Hormone Hormones and β-stimulants commonly used in the aquaculture industry mainly include sex hormones, corticosteroids and clenbuterol hydrochloride. Many studies have shown that the excess residues of hormone drugs such as clenbuterol and diethylstilbestrol in animal-derived foods can greatly harm human health. Among them, clenbuterol hydrochloride (clenbuterol) is easy to cause residues in animal-derived foods. If healthy people consume more than 20 μg of clenbuterol hydrochloride, it is effective, and 5 to 10 times the intake of course poisoning.
Other veterinary drugs Furazolidone and nitrofuran hydrazone are often used in the feed of pigs or chickens to prevent diseases. They should have zero residue in animal-derived foods, that is, they must not be detected. They are banned veterinary drugs for food animals in my country. Benzimidazoles can accumulate in various tissues and organs of the body, and have high residues in meat, eggs, and milk during the administration period.
Why need BALLYA AniFast Test?
Veterinary drugs play a very important role in preventing and controlling animal diseases, improving production efficiency, and improving the quality of animal products. However, due to the lack of scientific knowledge and blind pursuit of economic benefits by farmers, the abuse of veterinary drugs is widespread in the current animal husbandry industry. The abuse of veterinary drugs can easily cause the residue of harmful substances in animal-derived food, which not only causes direct harm to human health, but also causes great harm to the development of animal husbandry and the ecological environment.
What is veterinary drug residue?
Veterinary drug residue is the abbreviation of “residues of veterinary drugs in foods of animal origin”. According to the definition of the Joint Legislative Committee on Food Residues of Veterinary Drugs in Foods of the Food and Agriculture Organization of the United Nations and the World Health Organization (FAO/WHO), veterinary drug residues refer to any The edible part contains the parent compound of the veterinary drug and (or) its metabolites, as well as impurities related to the veterinary drug. Therefore, veterinary drug residues include not only the original drug, but also the metabolites of the drug in the animal body and the impurities associated with the production of veterinary drugs.
The hazards of veterinary drug residues
1. Toxic effects If a veterinary drug remains in the body of an animal for a long time, when the animal is slaughtered for consumption, the residual drug will enter the human body. If the concentration reaches a certain level, it will have a toxic effect on the human body.
2. Allergic reactions Residual antibiotics such as penicillins and tetracyclines in milk foods can easily cause allergic reactions to the body, especially susceptible physiques, ranging from skin itching and urticaria to acute angioedema and shock, and even death.
3. Three effects It is carcinogenic, teratogenic, and mutagenic. Because some drugs can damage tissue cells, induce gene mutations and have carcinogenic activity, the "three causes" effects of veterinary drug residues should be paid more attention to.
4. Lead to resistance of pathogenic bacteria Regular consumption of food with low-dose drug residues can make bacteria resistant. After an animal frequently and repeatedly ingests a certain antimicrobial drug, some sensitive strains in the body will gradually develop resistance and become drug-resistant strains. These drug-resistant strains can enter the human body through animal food. Infectious diseases, it will bring difficulties to clinical treatment and even delay the normal treatment process.
5. Impact on the gastrointestinal flora Numerous bacteria are parasitic in the normal body. If long-term contact with low-dose antibacterial drug residues in animal foods, it will inhibit or kill sensitive bacteria, while the proliferation of drug-resistant bacteria or conditional pathogenic bacteria will make the human body micro-ecological The balance is disrupted, and the body is prone to infectious diseases.
6. Impact on ecological environment quality After being administered to animals, some drugs with stable properties can still exist stably after being excreted into the environment with feces and urine, resulting in drug residues in the environment. The application of high copper, high zinc and other additives, and the extensive use of organic arsenic can cause soil and water pollution.
Causes of veterinary drug residues
(1) Residual veterinary drugs are produced during the prevention and control of livestock and poultry diseases. (2) Use low-quality, prohibited veterinary drugs and their compounds. (3) The environment and animal feed are polluted by veterinary drugs. (4) Use veterinary drugs assault. (5) Residues of veterinary drugs in the ecological environment. (6) Insufficient management and unsound testing technology and standards.
How to reduce veterinary drug residues?
(1) Widely publicize and raise awareness (2) Use veterinary medicine feed correctly (3) Promote standardized breeding of livestock and poultry (4) Strengthen the research and development of safe drugs (5) Improve institutions and strengthen veterinary drug testing (6) Strictly enforce the law and strengthen supervision
The medical profession has confirmed that the abuse and residues of antibiotics, hormones and other synthetic drugs in livestock and poultry products are often related to common human cancers, deformities, drug resistance, juvenile precocious puberty, middle-aged and elderly cardiovascular diseases, and certain food poisoning. related. Excessive chemical drug residues are a very important reason to restrict exports. If drug residues are not paid attention to, it will eventually hinder the development of animal husbandry, and more importantly, damage the health of the people. Some stable drugs can still exist stably for a long time after being discharged into the environment, resulting in drug residues in the environment. These residual drugs slowly accumulate in the human body and other plants through animal products and the environment, and finally collect in the human body, resulting in the increase of human drug-resistant bacteria, loss of resistance to certain diseases, or poisoning of the carcass due to a large amount of accumulation effect. Therefore, the detection of veterinary drug residues in feed is an important preventive method.
Conclusion
With the development of society, the animal husbandry industry is becoming more and more modern, intensive and large-scale. The use of veterinary drugs can reduce morbidity and mortality, increase feed utilization, promote growth and improve product quality. It has become an indispensable material basis for modern animal husbandry. However, due to the lack of scientific knowledge and economic interests, the abuse of veterinary drugs and excessive use of veterinary drugs are widespread, and the consequences are unimaginable. The BALLYA AniFast Test provided by BALLYA can effectively detect veterinary drug residues in various feed and aquatic products. Its simple operation, short detection time and high accuracy are major features of this product.
