Understanding the role of cleaning in the control of Salmonella Typhimurium in grower-finisher pigs: a modelling approach
R Gautam, G Lahodny, M Bani-Yaghoub… - Epidemiology & …, 2014 - cambridge.org
Salmonella Typhimurium (STM) infection in pigs represents a considerable food safety
concern. This study used mathematical modelling to evaluate the effectiveness of cleaning
(faeces removal) as a measure to control STM spread among grower-finisher pigs. A
modified Susceptible-Infected-Recovered-Susceptible (SIRS) model of STM transmission
through a contaminated environment was developed. Infected pigs were divided into three
states according to the pathogen level being shed in their faeces. Infection transmission was …
