- aggregation title "The evaluation of the food safety management system of a hospital food service operation towards L. monocytogenes".
- aggregation abstract "Introduction : During the last 15-20 years there has been an increasing concern world-wide about L. monocytogenes and its implications for food safety. Listeriosis is lately associated with elderly people and those persons who are immune-compromised by medications or illness such as frequently encountered in hospital settings. Consequently, the occurrence, spread, growth and survival of L. monocytogenes in foods and the food environment of hospital food service operations has to be carefully controlled. Materials and methods : The context, performance and food safety output of the current food safety management system (FSMS) in place in a hospital food service operation was evaluated, in particular with respect to L. monocytogenes, according a Diagnostic Instrument (Jacxsens et al., 2011). The diagnostic instrument consists of comprehensive lists of indicators to analyse which core control (e.g. cleaning and disinfection, cold chain) and core assurance activities (e.g. sampling plan, audits) are addressed in the company specific FSMS, which context factors could affect the FSMS and to analyse the microbiological safety performance of the FSMS. In addition on 3 separate occasions, sampling for L. monocytogenes in the food service operation was performed (including environmental swab samples and product samples). Results and discussion : During sampling L. monocytogenes was absent in all (n= 145) environmental samples and detected in 7/49 product samples namely in cooked, salt-free ham, raw meat sandwich spread, smoked salmon, raw salmon (two times) and raw chicken meat. According the Diagnostic Instrument the food service operation (FSO) is operating in an medium risk context. The hypothesis of the diagnostic instrument for a FSO with a medium risk context is that an average FSMS should be sufficient to cover the risk of L. monocytogenes. However, according to this diagnosis tool in the FSO only a moderate food safety output is reached. This is due the lack of assurance activities such as a sampling plan to control L. monocytogenes in the FSO and the validation and verification of the production process. Conclusion : The evaluation of the FSMS according a diagnostic instrument can be used to identify the weak points of the FSMS and to adjust its FSMS to improve food safety output. In addition the awareness on the issue of L. monocytogenes (which was overall quite low in the food service operation) was raised because of this internal validation study of the FSMS using the diagnostic instrument and sampling.
