Antimicrobial: Uses and Risks

An antimicrobial agent is a naturally occurring, semi-synthetic, or synthesized chemical that at doses attainable, demonstrates antimicrobial action and contains molecules that are effective against bacteria, viruses, , and fungi that either kill or prevent the growth of microorganisms. Antimicrobials are efficient at limiting, preventing, or eliminating the growth of microorganisms in both humans and animals and their answerable use avoids the development, persistence, and dissemination of resistant microorganisms. Veterinarians must be aware of which and how antibiotics to use in food animals must also be made regarding human health and the environmental impact. Illegal and excessive use of antimicrobials in livestock breeding has major harmful effects, such as leaving residues in animal products and posing a risk to humans. The most obvious reasons for undesired residue are long-acting medications, overdosing, and not adhering to the withdrawal phase. Regulations concerning antimicrobial residual limits should strictly adhere to withdrawal periods.
