Evaluation of biosecurity measures as a factor influencing antimicrobial resistance in semi-intensive poultry farms in three municipalities of Kinshasa

Abstract

The poultry farming sector constitutes a major pillar of food security and economic growth in several African countries. However, the persistence of various pathological conditions hampers the development of this sector, leading to substantial socio-economic and public health losses. In response to these multiple challenges, the implementation of new strategies aimed at preventing infections in poultry farms and reducing antimicrobial use is critically important. This study aimed to assess the current status of biosecurity practices as a factor influencing antimicrobial resistance in three peri-urban areas of the city of Kinshasa. Based on a survey conducted among poultry farmers, it was found that only 24% of farms had a footbath at the farm entrance, and 16% were equipped with handwashing or disinfection facilities. The presence of rodents and flies (80%), cockroaches (60%), lizards (40%), and wild birds (20%) was reported. The main diseases encountered included coccidiosis (30%), colibacillosis (28%), Newcastle disease (18%), avian pox (10%), Gumboro disease (8%), and Marek’s disease (6%). Overall, the results of this study demonstrated a low level of implementation of biosecurity measures related to farm personnel, visitors, animals, as well as materials and equipment.
