Research Advance on the Veterinary Drug Residue and Its Ecological Environment Impact

As the extensive use of veterinary drug and feed additive,the drug residues in animal foods become more and more serious,which threatens human health and public environment.Veterinary drug or their metabolites could be released to the soil environment through different exposure routes,and had adverse effect on soil environment including ground water.Those can bring poison impacts on ecological environment through food chain further,and affect normal life activities of animal,plant,microorganism and biology group and ecosystem balance.In this paper the veterinary drug residue and its ecological environment impact were reviewed.
