Background and Goals
This study aimed to model the effects of antibiotic usage in livestock on human health, particularly focusing on the incidence of salmonellosis. The goal was to understand the potential consequences of curtailing antibiotic use in livestock on public health.
Materials and Methods
A mathematical model was developed to simulate the dynamics of antibiotic usage in livestock and its impact on human health outcomes. Data from various case studies involving ampicillin and tetracycline usage in pigs and poultry were incorporated into the model.
Results
The model predicted that reducing antibiotic usage in livestock could lead to an increase in the incidence of salmonellosis in humans. However, the extent of this increase was found to be negligible to controllable with appropriate interventions.
Conclusion
While reducing antibiotic usage in livestock is essential for combating AMR, it must be accompanied by enhanced biosecurity measures and improved farm-to-fork hygiene practices to mitigate potential public health risks.
