摘 要:
Chicken meat is highly susceptible to spoilage and frequently implicated in foodborne disease outbreaks. When appropriate handling practices, processing and storage facilities are lacking, as is often the case in the informal sector, there is an increased risk of transmission of
zoonotic diseases and rapid spoilage with economic and health-related losses. Globally, chicken meat is considered a significant product pathogen pathway for Salmonellosis and campylobacteriosis. The first study was to investigate the provides empirical evidence of the microbiological pathogens on chicken carcasses and processing environments, and the prevalence, distribution and MDR Salmonella serovars in poultry environments in Accra, Ghana. The result show that most prevalent Salmonella serovars in chicken processing environments were S. Typhimuruim, S. Infantis, S. Enteritidis and S. Newport. The aim of the second study was to evaluate the determine the effects of organic and RWA methods on Campylobacter prevalence and AMR during processing. All of these observations indicate that raising broilers using RWA methods may not result in lower levels of AMR Campylobacter. Finally, as there was no major difference in AMR between organic and conventional isolates,
and conventional birds were treated with nicarbazin and zoalene, this indicates that use
of ionophores as anti-coccidia measures may not select for co-resistance to any of the
antimicrobials tested.
