EFSA Scientific Opinion on Listeria monocytogenes in Soft Cheeses
The European Food Safety Authority (EFSA) has published a scientific opinion regarding Listeria monocytogenes, a pathogenic bacterium with significant public health implications. Soft cheeses, especially those made from raw or pasteurized milk and aged for less than 90 days, are considered high-risk foods due to the potential for Listeria contamination during production, handling, or consumption.
The EFSA's scientific opinion focuses on the prevalence of Listeria monocytogenes in soft cheeses and its public health significance. The report aims to provide evidence-based recommendations to support food safety policies, particularly for countries where soft cheese consumption is high. This includes identifying critical control points during manufacturing, storage, and distribution that could reduce the risk of contamination.
The primary goal of this scientific opinion is to inform decision-makers in public health bodies about the most effective strategies to mitigate the risks associated with Listeria monocytogenes in soft cheeses. Key areas addressed include:
- Identification of high-risk products and production practices.
- Evaluation of control measures during processing, storage, and distribution.
- Determination of appropriate sampling strategies for monitoring compliance with regulatory standards.
The report also emphasizes the importance of microbiological testing to ensure that soft cheeses meet stringent safety requirements. Compliance with regulations such as EU Regulation 2019/438 on Listeria monocytogenes is crucial for maintaining food safety standards.
The testing process involves several key steps:
- Sampling: Representative samples are collected from different stages of production, including raw materials, in-process products, and finished goods.
- Culture Media: Samples are incubated on selective media like Tetrathion agar for presumptive isolation of Listeria.
- Confirmation Tests: Presumptive colonies are further identified using confirmatory tests such as API 20E or other methods.
- Quantification: Quantitative analysis may be performed to assess the level of contamination if present.
- Genotyping: Molecular techniques like pulsed-field gel electrophoresis (PFGE) can provide insights into the source and spread of Listeria.
The results from these tests are critical for verifying compliance with regulatory standards and ensuring that soft cheeses do not pose a risk to public health. The EFSA's recommendations are based on comprehensive data analysis, including reviews of relevant scientific literature, expert consultations, and stakeholder input.
For quality managers, compliance officers, R&D engineers, and procurement personnel in the food industry, understanding these testing protocols is essential for ensuring product safety and regulatory compliance. Regular microbiological monitoring helps prevent outbreaks and protects public health.

Environmental and Sustainability Contributions
The testing of Listeria monocytogenes in soft cheeses plays a crucial role in promoting public health while also contributing to environmental sustainability. By identifying and mitigating the risk of contamination, we help reduce the likelihood of foodborne illness outbreaks, which can have significant economic impacts on both consumers and producers.
In addition to ensuring product safety, our testing services contribute to broader environmental goals by:
- Reducing waste: Accurate testing allows for the identification of contaminated products early in the supply chain, minimizing the amount of food that needs to be discarded.
- Optimizing resource use: By identifying contamination sources and implementing effective control measures, we help reduce water and energy consumption associated with production processes.
- Promoting sustainable practices: Our services encourage the adoption of environmentally friendly practices throughout the food supply chain, from raw material sourcing to final product disposal.
The environmental benefits of our testing are not limited to immediate savings; they also contribute to long-term sustainability goals. By preventing contamination and ensuring compliance with regulations, we help create a safer and more sustainable food system for future generations.
