An improved challenge test for food products safety
An Italian biotech company has developed a new challenge test methodology able to simulate what happens to a product should it become contaminated, also identifying autochthonous contaminants and evaluating the efficacy of the procedures adopted. The test is performed inoculating microorganisms in raw ingredients or production plant to determine health hazards or spoilage risks. Companies in food sector are sought for commercial agreement with technical assistance.

This new microbial challenge test has been developed by an Italian company offering high-tech services to the agri-food and pharmaceutical industry regarding all aspects related to microbiology. The Microbial challenge test is widely used to simulate what happens to a product should it become contaminated. It is in general recommended for those food products that are known to be susceptible to pathogenic growth and spoilage. It is a must if there is a record of problems in actually meeting the shelf life expectations (see Annex II – Reg CE/2073/2005) The processing methods, formulations, and storage conditions also play a role in the evaluation if it could be useful to perform a Challenge Test (e.g. if the end products are shelf stable even at room-temperature or they are vulnerable to spoilage and/or pathogenic microorganisms' growth even if stored at refrigeration temperatures). Other parameters to take into account are a pH and water activity and the use of preservatives. Food products typically included in such studies range from shelf-stable salads and condiments, refrigerated ready-to-eat (RTE) products like pasta entrees and deli salads, dairy products and juice drinks, to modified atmosphere packaged (MAP) products such as vegetables, meats, poultry and fish, bakery items stored at room temperature, confectionery and food formulated using new preservatives. Nevertheless, Challenge tests should be conducted when the processor requires useful information about specific processing protocols, HACCP and to evaluate and tune up sanitization procedures. Even if the Challenge Test is a very powerful instrument to test all these critical issues, it is usually performed inoculating selected (type) microorganisms into a food or formulation and then followed to asses if it may become a potential health hazard or a source of spoilage risk. The main limit of this standard approach to Challenge Test is to focus its analysis on standard strains with no history of presence in the food or formulation under scrutiny. The New Challenge Test overcomes these limitations identifying autochthonous contaminant strains and then performing the test evaluating their behaviour during the process, ensuring the product meet regulatory mandates and/or established finished product specifications. Companies working in food sector and interested to check and monitor food safety are sought for commercial agreement with technical assistance.
Advantages and innovations
The new Challenge Test enables the evaluation of the behaviour of autochthonous contaminant strains during the process, ensuring the finished products meet regulatory mandates and/or established finished product specifications to avoid spoilage and/or pathogenic organisms naturally occurring in the product.

How it works
- Tell us about yourself
- We’ll discuss with you
- We put the right partners in touch
EEN help you find the right partner, rather than you going it alone.
Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.
These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.
Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
First we need to check you’re human.
