Methods of research synthesis - the process of bringing together the results of individual research to better map the knowledge base - have developed over the last couple of decades. Systematic review-meta-analysis (SR-MA) has been used in agri-food public health to a limited extent. The main purpose of this study was to evaluate the suitability of SR-MA in this area using Salmonella issue in pigs. Three areas were identified as potentially suitable for MA, prevalence, diagnostic test performance, and risk factor data.
