“…Additional data on Salmonella seafood-borne infection in the EU related to fish products, such as 'fish gratin' and 'sesame prawn toast' have been reported by some Authors (Guerin et al, 2004;Holtby et al, 2006), however, in both cases the responsibility should be ascribed to eggs used as an ingredient in the products.…”

“…Eggs, egg products and the use of raw shell egg have been significantly linked to foodborne outbreaks of Salmonella enterica serovar Enteritidis phage type 4 infections (Gillespie et al 2005). Other Salmonellas, notably S. Enteritidis PT14b, have also been linked to outbreaks from eggs imported into the UK (Holtby et al 2006). Holtby et al (1997) reported the isolation S. Enteritidis PT6 from several environmental sites including a reusable cleaning cloth in an outbreak caused by this Salmonella.…”

Summary This review looks at the contribution of microbiological sampling to the safety of retail foods in England and Wales. It compares sampling methods available and assesses the value of testing as part of outbreaks of foodborne disease, as part of routine management by local authorities, as part of work done or commissioned by the food industry, and as part of research. It confirms that microbiological testing has a role during outbreaks as it makes a significant contribution to help identify foods and other areas of greatest risk for future study. The review suggests that routine testing by local authorities is often of limited use and could be improved by more targeted surveillance. Testing could be better used to validate primary control methods, such as Hazard Analysis and Critical Control Point (HACCP) system. Any public health benefit from testing in the food industry is often restricted by client confidentiality. Microbial research on foods is important as it can lead to significant improvements in safety. Current microbiological methods are slow and, in future, rapid molecular methods may make an even bigger contribution to the control of foodborne disease.

“…Some fluctuations in prevalence of phage types were observed over time: PT1 predominated in 2007, PT21 in 2008, PT14b in 2010, PT8 in 2011 and PT4 in 2012. Like in other countries; these fluctuations are probably mainly due to outbreaks [ 23 , 24 ], [ 25 ] even if the sources of contamination could not always be identified [ 23 , 24 ]. The prevalence of PT28 increased over the six-year continuously.…”

Multi Locus Variable-Number Tandem Repeat (MLVA) Typing Tools Improved the Surveillance of Salmonella Enteritidis: A 6 Years Retrospective Study

et al. 2015

Surveillance of Salmonella enterica subsp. enterica serovar Enteritidis is generally considered to benefit from molecular techniques like multiple-locus variable-number of tandem repeats analysis (MLVA), which allow early detection and confinement of outbreaks. Here, a surveillance study, including phage typing, antimicrobial susceptibility testing and MLVA on 1,535 S. Enteritidis isolates collected between 2007 and 2012, was used to evaluate the added value of MLVA for public health surveillance in Belgium. Phage types PT4, PT8, PT21, PT1, PT6, PT14b, PT28 and PT13 dominate the Belgian S. Enteritidis population. The isolates of S. Enteritidis were most frequently susceptible to all antibiotics tested. 172 different MLVA profiles were detected, of which 9 frequent profiles included 67.2% of the S. Enteritidis population. During a serial passage experiment on selected isolates to investigate the in vitro stability of the 5 MLVA loci, no variations over time were observed indicating that the MLVA profiles were stable. The MLVA profile of isolates originating from different outbreaks in the Democratic Republic of the Congo (DRC) between 2010 and 2011 were distinct from any of the MLVA profiles found in Belgian isolates throughout the six year observational period and demonstrates that MLVA improves public health surveillance of S. Enteritidis. However, MLVA should be complemented with other subtyping methods when investigating outbreaks is caused by the most common MLVA profile.
