“This paper describes the development of a concept to measure the safety of the food chain in Belgium based on the ‘Pressure-State-Response’ model. The actual measurement tool or barometer consists of a measurement of the ‘State’ based on a set of indicators. The present paper discusses the elaboration of a set of 30 food safety indicators (FSIs) as the basis of the food safety barometer. These indicators were weighted by expert opinion in order to determine their relative weight to be considered in the barometer. Food safety was reflected in a composite
and agreed upon set of indicators related to i) the compliance Blasticidin S research buy AZD9291 inhibitor to action limits/criteria for selected chemical and microbial hazards, ii) the implementation of preventive and control measures to mitigate food safety throughout the food chain from farm to fork and iii) the reported number of foodborne outbreaks and reported cases of some selected zoonotic agents (Salmonella sp. and Listeria monocytogenes). As food safety remains an abstract term and no quantitative value could be attributed (also due to
lack of quantitative food safety objectives), the option was taken to document the status of food safety in a relative manner by comparing the results of the set of indicators of the current year with the previous year. By comparing the years 2007, 2008 and 2009 it was concluded that the status of the global food safety in Belgium was high and an upward trend could be observed. Statistical analysis on each of the individual indicators was performed, however since at present a restricted data set is available (2009 versus
2008 and 2008 versus 2007) no trend analysis could yet be performed. The barometer provides a helicopter view of the status of food safety in Belgium and is a tool to communicate in an intelligible, comprehensible manner on aspects of food safety to consumers and other stakeholders in the food chain. The methodology and results of the survey for the ‘Pressure’ and ‘Response’ collection from the Belgian DMXAA cost stakeholders in the food chain will be discussed in another manuscript.

“Composites of polyvinylidene fluoride (PVDF) filled with different conductive fillers as carbon black (CB), nickel (Ni), zinc (Zn), and tungsten (W), respectively, were prepared at same processing condition. The temperature dependence of dielectric behaviors of composites was studied at wide filler concentration and wide frequency ranges. Results show that there are giant dielectric constants as the concentration of filler is near the percolation threshold. The dielectric constants of all studied composites decrease slowly with increasing of frequency and rise gradually with increasing filler contents in the composites.
