Antibiotic Use in Livestock and Environmental Antibiotic Resistance: A Narrative Review.

ABSTRACT: Antimicrobial use in animal husbandry is a common practice in developing countries as a response to the growing demand for animal-based foods. Veterinary antibiotics account for most of the antibiotics used worldwide. This review aims to provide an overview of the impact of antibiotic usage in livestock production on the environment and its consequences in the emergence and spread of antibiotic resistance. The global estimate of antibiotic consumption in animals ranges from 63 000 to 106 000 tons annually. The most commonly used antibiotic classes include tetracyclines, sulfonamides, β-lactams, macrolides, and trimethoprim. Most of the antibiotics used in animal treatments are not fully metabolized within the animal's body; instead, they are excreted and can enter the environment. This rev
