Chapter 1 Key Objectives of this study The main objectives of this research were: 1. To investigate whether the strain of S. Agona SAGOXB.0066 that was responsible for a large food-borne outbreak differs in density of biofilm formation compared with other S. Agona strains and if any such differences are dependent on the biofilm substratum. 2. To evaluate if other serovars that are commonly associated with foodborne outbreaks, such as S. Enteritidis and S. Typhimurium, are similar to or different from S. Agona in relation to density of biofilm formed under the same conditions as the S. Agona investigated. 3. To examine the impact of time on density of biofilm formed. 4. To assess methods to eradicate Salmonella biofilm cells using disinfectants commonly associated with food processing areas. Page 35
