Pasture livestock systems have an essential role in promoting sustainable farming practices in Europe, but they have disadvantages, especially in terms of animal health, as grazing animals are highly susceptible to parasitic infections. They can apply a significant economic weight to the production process, so the most frequently used control method is the administration of anthelmintics. This review summarizes the research on the use of alternative anthelmintics on global scale, reprising the policy for helminth control with envisage of more sustainable solutions including safety, quality and risk assessment. This is in line with the objectives of the national and international plans on resistance to medications. The competitiveness in the livestock sector should stimulate us to look for more efficient and profitable alternatives for their farming. Helminths can cause chronic and sometimes fatal diseases that infect an estimated two billion people worldwide, but the misuse and overuse of antiparasitic drugs can cause serious global drug resistance problems as well. This necessitates the isolation and identification of new anthelmintic drugs for veterinary and human medicine.
