Process Monitoring in Regulated Production

Microbiological monitoring of production environments is a key component of food safety according to Regulation (EC) No 852/2004 and forms the basis for effective HACCP plans. We actively support you in implementing these plans through accredited analytical testing, standard-compliant sampling procedures (e.g., in accordance with ISO 18593), and expert evaluation.

Particularly in the processing of animal products, such as meat and milk, and in allergen-relevant production processes, systematic environmental monitoring enables the early identification of contamination risks. It supports compliance with labelling requirements in accordance with Regulation (EU) No 1169/2011.

Comprehensive Testing Approach in Regulated Production

Targeted analyses of surfaces, air, and process environments follow a risk-based, process-oriented approach and enable the assessment of microbiological or allergenic risks.

Pathogen Monitoring

Systematic testing for and microbial identification of Listeria spp., Salmonella, and other relevant pathogens on surfaces and in the production environment. Testing is conducted on a risk-based approach within the framework of HACCP and supports the early detection of critical sources of contamination as well as robust process control.

Cleaning Validation

Microbiological and allergen-related analyses to verify the effectiveness of cleaning and disinfection processes. Structured sampling ensures that residues and spoilage organisms are removed and that production lines can be safely used for subsequent batches.

Airborne Microbial Count Determination

Assessment of microbial contamination in the production air using active and passive sampling. The results enable an evaluation of hygienic conditions, support IFS-compliant measures, and help to minimise airborne contamination risks, such as spores and spore formers, in sensitive areas.

Allergen Monitoring

Targeted testing for allergen residues on surfaces, equipment, and in the production environment to verify the effectiveness of allergen control measures. Sampling is conducted risk-based in alignment with HACCP and supports the prevention of cross-contact, ensures compliance with labelling requirements, and enables reliable validation of cleaning processes between product changeovers.

Sampling Techniques

The selection of appropriate sampling techniques is crucial for valid results and reliable risk assessment in production.

Frequently Asked Questions

Common questions from operators of regulated food and pharmaceutical production environments.

We work with regulated food and pharmaceutical production environments, including processing areas, packaging zones, high-care and high-risk areas, wet processing environments, and classified cleanroom environments.

A robust programme combines surface swabbing, air monitoring, and targeted pathogen testing (e.g. Listeria spp., Salmonella). Sampling plans are risk-based and focus on critical zones to detect contamination early and verify hygiene performance over time.

Air monitoring identifies airborne microorganisms such as moulds and spores that can contaminate products, especially in sensitive areas. The results support hygiene assessments and help optimise air handling and sanitation measures.

Allergen monitoring detects residues on surfaces and equipment to prevent cross-contact between products. This is essential to ensure correct labelling, protect consumers, and comply with regulatory and customer requirements.

A structured swabbing programme is based on risk assessment and site mapping. It defines sampling points by zone (product-contact, near-product, environmental), frequency, target organisms and acceptance criteria – aligned with applicable food safety or pharmaceutical standards.
