Pork and pork products are considered to be a major source of human salmonellosis in the United Kingdom (UK). Despite a number of control programmes implemented within the UK, such as the Zoonoses National Control Programme (ZNCP), the prevalence of Salmonella in the UK slaughter pig population remains over 20% [1]. In particular, S. Typhimurium (including monophasic variants) continues to be a predominant serotype in humans, which is known to be most commonly found in pigs [2]. Therefore, to identify potential control measures that could reduce the number of human Salmonella cases it is necessary to understand the farm-to-consumption chain for pork and pork products. However, implementing control measures across the whole pig industry and food-chain would be a costly large scale project. It is therefore important to assess whether the benefit of implementing the control measures justifies the cost.
