What could be a consequence of MDR in food-producing animals?

The consequence of multidrug-resistant (MDR) bacteria in food-producing animals is indeed tied closely to increased antibiotic resistance in humans. When livestock are treated with antibiotics, especially in subtherapeutic doses or for growth promotion, it can lead to the development of resistant strains of bacteria. These resistant strains can then be transferred to humans through various pathways, including the food supply, direct contact with animals, or through environmental exposure.

As these MDR bacteria proliferate in the livestock population, there is a heightened risk of these bacteria entering the human population. This presents a significant public health threat, as infections caused by resistant strains are more difficult to treat, often requiring more complex and expensive therapies, leading to higher morbidity and mortality rates. Additionally, the spread of antibiotic resistance can lead to a situation where common infections that were previously easily treatable become challenging to manage, resulting in broader implications for healthcare systems.

The perception that there could be no impact on public health or that there would be improved livestock productivity or decreased meat prices does not align with the established understanding of the consequences of antibiotic resistance. Each of these scenarios fails to acknowledge the significant risks associated with the rise of resistant bacteria, not just for individuals but for public health as a whole.
