Prevalence of Salmonella and Escherichia coli in Pig Farms in Yopougon (Côte d'Ivoire)

Prévalence de Salmonella et Escherichia coli dans les élevages de porcs de Yopougon (Côte d'Ivoire)

Résumé

The microbiological contamination of pork is an increasingly important concern as pork consumption rises. This study aims to examine the microbiological contamination by Salmonella and Escherichia species in a pork production environment. To this end, fourty (40) fecal samples from pigs raised in enclosures on four (04) farms in the Yopougon municipality were collected and analyzed. Classical microbiological methods, including enrichment, pre-enrichment, selective media culture, isolation on ordinary agar, and biochemical tests, were employed to identify the specific biochemical characteristics of each bacterium. The overall prevalence of Escherichia species was 80% [70-90] across farms and 80% [66.7-100] based on pig status. Furthermore, Salmonella species showed a prevalence of 12.5% [10-20] according to the farm and 12.5% [0-20] based on pig status. These findings highlight the necessity of raising awareness among stakeholders in the pig farming sector about environmental hygiene and monitoring pig microbiota to reduce consumers' exposure to pathogenic and endemic bacteria of the Salmonella and Escherichia genera.

Furthermore, Salmonella species showed a prevalence of 12.5% [10-20] according to the farm and 12.5% [0-20] based on pig status. Ces résultats soulignent la nécessité de sensibiliser les acteurs du secteur de l'élevage porcin à l'hygiène de l'environnement et de surveiller le microbiote des porcs afin de réduire l'exposition des consommateurs aux bactéries pathogènes et endémiques des genres Salmonella et Escherichia.
