Microbial food spoilage: A major concern for food business operators

3 July 2012 | By François Bourdichon and Katia Rouzeau, Food Safety Microbiology, Quality and Safety Department, Nestlé Research Centre

‘Something is fishy’ is a widely used expression over a doubtful, suspicious situation, a good example of how mankind has taken advantage of microbial spoilage to assess the wholesomeness of a food product. The reduction of trimethylamine oxide to trimethylamine by bacteria associated primarily with the marine environment (e.g. Alteromonas…

Microbial biofilms – a concern for industry?

3 July 2012 | By Dr Evangelia Komitopoulou, Head of Food Safety, Leatherhead Food Research

Many bacteria are able to attach to and colonise environmental surfaces by producing a biofilm, which allows the organisms to persist in the environment and resist desiccation, UV light and treatment with antimicrobials and sanitising agents. Biofilms are formed when microbes attach to a solid support and to each other…

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 PubMed.gov database will produce over 600 results. Clearly, this has led to a huge choice of PCR-based…

Hygienic design requirements for components in hygienic and sterile processes

4 January 2012 | By Ulf Thiessen and Matthias Schäfer, EHEDG Subgroup Valves

The major objective of hygienic design is to avoid product contamination by microbes, particles and chemicals. European legislation (i.e. the Machinery Directive) is forcing machinery suppliers to design their machines which are used in the production of food, pharmaceuticals and cosmetics according to some so-called hygienic design criteria. The common…

Re-adhesion of bacterial spores during CIP procedures

15 December 2010 | By Christine Faille, INRA, UR638 Interface processes and hygiene of materials

Cleaning In Place (CIP) procedures have to ensure hygiene in food processing lines by the complete removal of bacteria from surfaces. However, a significant number of residual microorganisms are often still observed following CIP. At INRA, we put forward the hypothesis that some of the detached micro-organisms might re-adhere downstream.…

Whole room disinfection – potential for environmental pathogen control?

5 November 2010 | By Alicja Malinowska & John Holah, Campden BRI

To meet retailer, customer and consumer expectations, there are increasing demands within the food industry for higher standards of microorganism control in food production environments. Traditional approaches such as cleaning and disinfection regimes have been targeting specific sites within the processing environment to control contamination. Such sites might include food…
