Responsible and prudent use of anthelmintic chemicals to help control anthelmintic resistance in grazing livestock species

Antiparasitic resistance is an important challenge across the world, including all World Organisation for Animal Health (OIE) regions. This type of resistance poses a significant threat to animal health and welfare and can result in production losses in food-producing species, thus presenting a challenge for food security.

The results of two surveys that were conducted in Africa; the Americas; Asia and the Pacific; Europe and the Middle East in 2020 and 2021 to assess antiparasitic agents and resistance and the prudent use of anthelmintic chemicals, respectively are incorporated into this document, which focuses on anthelmintic resistance in grazing livestock.
