Abstract
ObjectiveAntimicrobial 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. MethodsData 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. ResultsThe 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). ConclusionStrict 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.
