4 November 2013 | By Inés María López-Calleja Diaz, Silvia de la Cruz, Nicolette Pegels, Isabel González, Teresa García, and Rosario Martín, Department of Nutrition, Food Science and Food Technology, Complutense University of Madrid

Food allergies are a serious public health problem. Around one to two per cent of the population suffer from some type of food allergy and even higher prevalence levels (up to eight per cent) are estimated for children. Peanut (Arachis hypogaea) allergy is one of the most severe food allergies…


Appropriate controls for PCR detection of foodborne pathogens

30 April 2012 | By Martin D’Agostino, Microbiologist, The Food and Environment Research Agency

Over the years, there has been a great increase in the number of PCR based assays for foodborne pathogen detection. For example, a very basic search for ‘salmonella food PCR assay’ using the database will produce over 600 results. Clearly, this has led to a huge choice of PCR-based…


Same-day PCR testing of Salmonellain meat: From research to routine application at slaughterhouses

7 July 2011 | By J. Hoorfar, C. Löfström & M.H. Josefsen, National Food Institute, Technical University of Denmark and F. Hansen & S. Mansdal, Danish Meat Research Institute and J. Andersen, Danish Crown A/S and G. Pedersen, TiCan amba
