Microbial Spoilers In Food 2013 | 1 - 2 - 3 July 2013 - Quimper

Super spoilers, wonder spores and diehard microorganisms : New insights to integrate these super foes in food spoilage risk management.

There is always ONE, ONLY ONE, BUT ONE which is able to resist or resuscitate after inactivation processes, which is able to adapt or is naturally adapted to acid and/or low moisture formulations, as well as low temperature and/or heat treatment,… and this ONLY ONE is finally able to grow causing food spoilage and economical losses! This only one is always of major concern for food quality and production managers. How does one deal with them? One way to proceed is to learn more about these diehard microorganisms.

This will be the challenge of the Microbial Food Spoilers symposium, to gather together on this specific topic: scientists, food quality and production managers, project leaders in food innovation and exchange knowledge and experience.

 This symposium will focus on the
- Biodiversity of microbial food spoilers,
- Caracterization methodologies, enumeration methods for quality indicators,
- Spoiler behaviour, fitness and functional properties,
- Inactivation processes and product stability assessment,
- Spoiler/pathogen and quality indicators/pathogen boundaries,
- Spoilage risk assessment.

Many topics to be covered by YOU !

Map'Opt project
Equilibrium gas composition in modified atmosphere packaging and food quality

The objective of this project is to explain, quantify and model the effects of modified atmospheres on microorganisms growth according to O2/CO2 transfer through the packaging and within food. The main factors that will be studied include the characteristics of films (gas permeabilities), headspace and food gas composition, gas diffusion properties within food, headspace volume and the weight of the food product. Only non-respiring food products will be studied (thereby excluding fresh vegetables and fermented food products such as cheeses or seafood products). This project integrates diverse fields of knowledge, drawing from material science, food science, microbiology, packaging, computer science and mathematical modeling.

Concerning the computer science field, this project deals with the research topic on ontology evolution in a data integration system. More precisely, this project relies on the existing Sym’Previus data integration system which must be complemented in order to capitalize the new knowledge on gas diffusion. Consequently the Sym’Previus domain ontology must also be complemented to take into account this new knowledge. In this project, the pertinence to merge the Sym’Previus ontology with other ontologies, available on the Web, to bring additional knowledge about measure units, terminology used for food product names will be studied. This project will also provide information to assess the dangers of food products under modified atmospheres according to selected shelf life.

Existing knowledge and simulation tools that have already been developed in the Sym'Previus project will help to assess the development of pathogenic microbes in food products. By including the possibility to simulate microbial behavior according to gas mixture, it will be possible to evaluate the risks and the benefits of using modified atmospheres in terms of shelf life and the potential related hazard.

ADRIA Développement will be in charge of mathematical modelling the effect of gases on the bacterial behaviour in food and software development.

ADRIA Développement is the project coordinator of Map'Opt.

Each year, IDF and ISO organize the IDF/ISO Analytical Week, hosted by an IDF National Committee. During a week of business meetings, the members of Standing Committees and Project Groups network and progress the standardization of international IDF/ISO standards, and other related items. This week is articulated around an international symposium tackling topical subjects of interest in the field of methods of analysis and sampling, and comprises an exhibition of analytical providers.

The IDF/ISO Analytical Week is the annual topical event for experts in the field of standardization of methods of analysis and sampling for milk and milk products. It will be organized and hosted by the French Committee of IDF: FIL France, in the city of Lyon from the 23rd to 27th of May 2011.

A symposium will be organized during the week. The symposium is likely to cover other fields than those merely related to analysis and sampling. The symposium is embedded in a series of business meetings of IDF/ISO Project Groups and the six IDF Standing Committees in the field of analytical methods of sampling and analysis.

ADRIA is partner of the IDF/ISO Analytical Weeks. You can visit our stand during the week. Danièle SOHIER, Florence POSTOLLEC and Cédric TRAVAILLE will be delighted to meet you and discuss our field of expertises.

ADRIA will participate to a technical workshop on Wednesday the 25th « New analytical methods and services : the dairy industry turns an ear to its suppliers ». From 16:20 to 16:50 : ADRIA / Sym’Previus and Aw Designer decision making tools. Speakers : Florence Postollec & Thibaud de Broucker

ADRIA will alsobe delighted to meet you at the Sponsors' cocktail on Wednesday the 25th, from 18.00 to 19.00

With more than 20’s year experience, ADRIA is one of the most important expert lab which provides ISO 16140 validation of alternative methods in the food microbiology scope. Based on the available certificates, 39,6% of the ISO 16140 validation studies were done by ADRIA, while 8 experts labs were operating.

 ADRIA operates for AFNOR Certification and more recently for MicroVal, while Nordval and AOAC-RI recognise the results provided by ADRIA through the manufacturers. ADRIA performs ISO 16140 validations since 2004, an AFNOR standard was used before.

Of course, it is easy to communicate about the validation studies success…But, sometimes, the validation study results highlight some improvement needs of the tested alternative method. In both cases, ADRIA know-how shall provide confidence in the study results, i.e. confidence of the certification body, and confidence of the manufacturers. Many manufacturers perform preliminary tests in ADRIA before starting a validation study, in order to get advices on the method practicability, but as well to be sure that no more improvements are required. Note that, due to strong relationship with the food industry, ADRIA has facilities to get naturally contaminated samples, from various origins, representative of the “true life” in the food industry sector.

6 months are usually required for the validation study, including the methods comparative study, the inter-laboratory study, and the relationship with the certification body. A specific ADRIA team works on validation studies, with Danièle Sohier as project manager, and Maryse Rannou as technical manager.

Experiments and quality assurance:

Of course, ADRIA’s got accreditation according to the ISO 17025 standard (www.cofrac.fr) and quality assurance procedures for all the experiments involved in the validation studies:

-          Protocols for artificial contaminations of samples,

-          Technical protocols which fit of course with the experimental designs described in the ISO 16140 standard and/or the certification body technical rules,

-          When disagreements are observed between the reference and alternative method results, ability to rapidly identify isolates according to the appropriate phenotypic or molecular methods,

-          Organisation of ring trials,

-          Statistical interpretations of the results according to the tests described in the ISO 16140 standard.

 Collection of strains:

The extended collection of micro-organism strains is of course under quality assurance, and provides a wide range biodiversity of Listeria spp, Cronobacter sakazakii, Escherichia coli O157:H7, Staphylococcus spp., Bacillus cereus group, Clostridium spp, Highly Heat Resistant spore forming bacteria species, spoilage micro-organisms, Enterobacteria, lactic acid bacteria, yeasts and moulds...

The strains are all identified according to the recent taxonomy evolution, characterised using appropriate phenotypic or molecular methods (serotyping, molecular fingerprinting, cardinal values, heat resistance parameters…)

The 38 methods that have been validated by ADRIA are listed in attached documents. Several of these methods are based on PCR detection.

 The SPORE2009 international scientific symposium was a remarkable success: it attracted 130 participants from 27 countries. The large participation of the food & diagnosis industries (30% of the participants), the contributions of the leading academic and technical organisations on the developed topics, highlighted the widespread interests related to "Spore forming Bacteria in Food". Indeed, we were at maximum capacity due to the overwhelming response and interest from presenters, speakers, and attendees!

The range of subjects covered by the communication panels included biodiversity and prevalence, systems biology, quantitative risk assessment, new advances in rapid analysis tools, epidemiology, food spoilage, positive microflora, adhesion to equipment surfaces, spore resistance and process optimisation. The conferences produced a variety of perspectives on increasingly critical issues, and new strategies for better control.

Communications have been selected for publication in a Food Microbiology Special Issue, which will be available at beginning of next year (january-february 2010).
Proceedings are gathered in an ISBN reference, in order to facilitate bibliographical references linked to the SPORE2009 international symposium. Proceedings could be registered directly from a website.
At least, presentations are online available to the SPORE2009 participants, by access using a personal link.

SPORE2009 success story is as well a never-ending story... see you soon at the next symposium!
