The problem of residues in meat of edible domestic animals after application or intake of organophosphate esters

Anthelmintic activity of Ziziphus nummularia (bark) and Acacia nilotica (fruit) against Trichostrongylid nematodes of sheep

“…But, nematodes have developed resistance against several families of anthelmintics (Kaplan, 2004;Jabbar et al, 2006a). Toxicity due to inappropriate dose administration and risk of drug residues in animal products are other big problems associated with the use of synthetic drugs (Kaemmerer and Butenkotter, 1973). These problems associated with synthetic anthelmintics led to the revival of interest in medicinal plants.…”

In Vitro Evaluation of Anthelmintic Efficacy of Some Plant Species Possessing Proteinases and/or Other Nitrogenous Compounds in Small Ruminants

“…They have the potential of being sustainable in addition to their environmental friendly nature [12,13]. Plant-based remedies are also credited with being non-resistible compared to chemical ones, and do not lodge chemical residues in animal products and the environment [14][15][16]. They also possess fewer or no side effects and contraindications relative to chemical anthelmintics [17].…”

In Vitro Studies on the Effect of Ethanol Extract of Syzygium Aromaticum on the Carbohydrate Metabolism of Cotylophoron Cotylophorum

“…However, problems have emerged with the use of synthetic anthelmintics, notably the development of resistance in helminths to various anthelmintic compounds and classes, as well as chemical residues and toxicity problems [4,5]. In addition, recognition of the antigenic complexity of parasites has slowed vaccine development.…”
