Preharvest Antibiotic Use and Salmonella Resistance in Nigerian Poultry and Swine Farms

3,600 fecal samples from commercial poultry and swine farms in Lagos, Nigeria were analyzed for Salmonella prevalence and antimicrobial resistance. The study, authored by Timothy Obiebe Jason Odey and last updated in April 2026, found a 1.5% Salmonella prevalence and widespread multidrug resistance, correlating antibiotic use practices with resistance phenotypes.

Use Cases

• Modeling correlations between farm management practices and antibiotic resistance based on questionnaire and microbiological data.
• Analyzing the distribution of specific resistance genes (e.g., tetA, sul1) and virulence factors across animal species.
• Assessing the public health risk of multidrug-resistant Salmonella strains from food animal production.

Strengths

• Includes data from 3,600 samples, providing a substantial sample size for analysis.
• Reports specific prevalence rates (e.g., 1.5% Salmonella, 0.67-2.2% by species) and resistance percentages (e.g., 80-100% erythromycin resistance).
• Correlates farm-level questionnaire data with laboratory-derived resistance phenotypes and genotypes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is limited to a single region (Lagos, Nigeria) and may not be generalizable.
