Call for partners: Listeria Hurdle Strategies


Call for partners: Listeria Hurdle Strategies

Wageningen Food & Biobased Research invites partners from the food industry to participate in a multi-partner consortium project aiming to develop optimal preservation strategies against Listeria monocytogenes. In particular for ready-to-eat food products, L. monocytogenes contamination forms a high food safety risk. This project will support the industry by developing new hurdle strategies for this food pathogen and design models to describe the combined (additive / multiplicative / synergistic), effects of combinations of hurdles. This should enable food manufacturers to maximize their product shelf life and secure food safety more efficiently.

Because L. monocytogenes forms a risk in ready-to-eat products, food manufacturers should study the outgrowth potential in these products. Challenge testing for L. monocytogenes is time consuming and therefore costly. The use of predictive modelling can reduce the amount of required experiments to prove the applied preservation strategy by limiting experimental work to the validation of the model predictions. Models currently available include factors such as pH, water activity, temperature, heat inactivation but information on effects of (combinations) of natural preservatives and processing is lacking.

This project will investigate the efficacy of natural anti-microbial ingredients and mild preservation methods. We’re aiming to find combined effects between the different hurdles that inhibit L. monocytogenes growth. This information will feed the models. The development of predictive models to describe and predict responses of Listeria monocytogenes new combined hurdles will enable the partners to optimize shelf life and safety of their food products more efficiently.

Want to join us?

This consortium is open for participation from all relevant stakeholders within the ready-to-eat food production chain from ingredient companies to consumer goods manufacturers. In return for in-cash and in-kind contributions to the project, partners can specify side-streams and end-products for research, and provide direction to the research activities. Unfortunately we are not able to reply to solicitations from research institutes or enquiries from students related to this project. We would be pleased to further discuss the opportunities within PPP LISTERIA for you.
