ECOLOGICAL SAFETY AT THE ANTIPARASITIC TREATMENT OF ANIMALS
One of the main features of parasitic pathology today is the lack of specific prevention. The vaccines developed by Soviet scientists against dictiocaulosis, coenurosis, fascioliasis, strongyloses, and others are not put into practice. Therefore, annually domestic animals are infected with more than 165 types of pathogens of parasitic diseases - helminthiasis, protozoiasis, arthropodiasis. Most of them are seasonal and cause great damage to the livestock industries. The use of antiparasitic drugs for different pathologies have their own characteristics. These are doses, methods of administration, route of administration, timing of residual activity and elimination from the body, and others. Residual components of medicines in the environment are not decomposed for a long time, they are not neutralized and remain in the soil, water, vegetation, disturbing the ecological balance of a specific biotope, territory, system. The massive use of antiparasitic agents can lead to environmental pollution, and their prolonged use leads to the development of strains of parasites that are resistant to the action of drugs. In our veterinary practice we use chlorophos, hexachloran, sevine, trichlormetaphos, creolin, creolin X, phenothiazine, drugs of albendozole, nilverm, fenbendazole, santel, rolenol, berenyl, neosidine, etc. We have previously noted that long-term use of chlorophos, phenothiazine, albendazole, nilverm preparations, berinil reduces their antiparasitic efficiency by 50% or more. They remain in milk and products of slaughter for a long time and pollute the environment through feces and urine.
