Objective: Antimicrobial consumption surveillance is a useful tool for planning antimicrobial resistance control strategies and risk analysis. The present study was carried out to evaluate the consumption trends of antimicrobials for veterinary use in food-producing animals in Cameroon from 2014 to 2019.
Methods: Data on quantities of classes of active substances were collected from the records of the technical authorization to import veterinary drugs of suppliers' invoices at the Ministry of Livestock (MINEPIA); animal population data were collected from the FAO-Stat database.
Results: The study revealed that 217.67tonnes of antimicrobials (by weight of active substance) were imported during the 6-year period, with an average of 36.28±10.11tonnes per year. Tetracyclines (31.71%), sulfonamides (23.84%), quinolones (11.11%) and β-lactams (10.17%) were the most commonly imported classes of antimicrobials. With regard to the importance of veterinary antimicrobials to human medicine, critically important antimicrobial (34.3%), reserve (4.6%) and watch (25.5%) groups as classified by the WHO AWaRe categorization were recorded. Overall, a mean of 5.24±1.40mg/PCU (population correction unit) was used in all food-producing animals during the 6-year period. However, the mean quantity of antimicrobials adjusted by animal biomass was highest in poultry (213.32±50.26mg/kg), followed by pigs (63.04±18.87mg/kg), cattle (4.11±2.20mg/kg), sheep (0.83±0.43mg/kg) and goats (0.47±0.24mg/kg).
Conclusion: Strict surveillance systems of antimicrobial consumption in the country are vital to optimize control strategies. Monitoring importation data of veterinary antimicrobial products could be useful for sub-Saharan African countries to quantify consumption and estimate trends for antimicrobial usage effectively.
