Food

The safety and quality of food products and ingredients is essential for a healthy and sustainable diet. With our microbiological tests, we control and evaluate the quality and safety of food.

As an ISO 17025-accredited test institute, Labor LS supports the food and feed industry in quality control, thus laying the basis for sustained trust on the part of customers and consumers. In addition to a wide variety of foods, we also test food supplements, raw materials for the food industry, animal feed, probiotic cultures, drinks and drinking water.

Whether food microbiology, hygiene management or differentiation: we supplement our regulation-compliant test methods with our own method developments. In addition, we create project implementation plans tailored to the individual needs of our customers.

Food Microbiology

Our microbiological analyses are carried out in accordance with the methods of § 64 of the Official Compilation of the German Food and Feed Code (LFGB) and ISO methods, standard operation procedures (SOPs) and customer-specific methods.

Our qualitative and quantitative microbiological analyses are carried out in accordance with the methods of § 64 of the Official Compilation of the German Food and Feed Code (LFGB) and / or ISO methods, standard operation procedures (SOPs) as well as customer-specific methods. The evaluation of the results is made according to the guidelines of the German Society for Hygiene and Microbiology (DGHM).

In addition to microbiological testing, the processing of samples includes the specimen collection and processing as well as the evaluation according to the “four-eye principle”, the creation of a certificate and the archiving of the data (for up to 10 years).

The following microbiological individual parameters are an extract from the methods established in our laboratory:

  • Aerobic, mesophilic or thermophilic bacteria
  • Anaerobic, mesophilic or thermophilic bacteria
  • Bacillus cereus
  • Bifidobacterium sp.
  • Campylobacter
  • Clostridia (sulphite-reducing)
  • Clostridium perfringens
  • Coliform bacteria
  • Cronobacter sakazakii
  • Enterobactericaea
  • Escherichia coli
  • Enterohemorrhagic E. coli (EHEC)
  • Enterococci
  • Yeasts and moulds

Quantification and Identification of Probiotic Bacteria

The potentially health-promoting effect of probiotic foods depends largely on the number of viable bacteria in the intestines after stomach passage, and on their appropriate positive properties.

The potentially health-promoting effect of probiotic foods depends largely on the number of viable bacteria in the intestines after stomach passage, and on their appropriate positive properties. To detect the presence of the desired microorganisms (e.g. genus Bifidobacterium, Lactobacillus and Lactococcus) in food, we conduct the appropriate and validated procedures for the quantification and identification (see chapter on molecular testing methods) of the probiotic bacteria. In this way, we cannot only determine the entire quantity of probiotic bacteria in a sample, but also differentiate and quantify various germs.

Labor LS provides on-site help. Our experts visit, consult, train, create and update hygiene plans and assess and monitor production processes and production facilities.





Our service portfolio includes:

  • Plant inspections, audits and consultations in accordance with IFS, BRC, etc.
    We can offer you a tailor-made service package for the on-site inspection of your company (premises, product-specific processes, inspection of test and hygiene plans including their documentation) as well as the resulting expert opinion and other services such as proposals for changes, monitoring, creation of HACCP concepts, etc. in accordance with your targets. In the event of a crisis situation, we respond reliably, fast and discreetly and are at your side to provide help and advice.

    The samples obtained for industrial-hygiene purposes such as smears, blots, airborne bacteria samples or washings are directly tested in the laboratory, and the cultivated colonies identified on request. Also food samples from canteens and clinical samples such as stool or sputum samples can be tested for salmonella or other potential pathogenic microorganisms. As a matter of course, we can provide the devices necessary for sample collection (calibrated air samplers, adapters for compressed air measurements) and materials (sterile swabs, contact plates, disposable containers).
  • Trainings for Industrial and Staff Hygiene
    We will be pleased to assist with the on-site training of your employees in all questions concerning industrial and staff hygiene, complying with your individual requirements and needs. The service package for on-site staff training includes, next to a qualified lecture and appropriate examples, the previous technical research and the answering of your employees' questions, of course.

Identification/Molecular-Biological Test Procedures

For the identification of bacteria, yeasts and moulds, we use phenotypic routine methods using instrumental techniques (API, VITEK, MALDI-TOF-MS) and sequencing techniques.

For the identification of bacteria, yeasts and moulds, we use phenotypic routine methods using instrumental techniques (API, VITEK, MALDI-TOF-MS) and sequencing techniques.





You can choose between two service packages:

  • Exploratory tests (subculture, microscopy, biochemical or for immuno-biological marker reactions, etc.) for the exclusion of microorganisms and for genus diagnosis
  • Species identification for suspicious/hygienically-relevant isolates (after-subculture and positive marker reactions)

Further molecular-biological test methods:

  • Specific detection of genetic modifications in food and feed
  • Differentiation of animal species using PCR analysis on cytochrome b gene, and the restriction fragment length polymorphism method (RFLP)

VDI 2047-2

Directive VDI 2047-2 has been in force since January 2015. It describes the hygienic operation of evaporative cooling systems. This includes the treatment of cooling water and the consistent combatting of germs harmful to health.

 

Directive VDI 2047-2 has been in force since January 2015. It describes the hygienic operation of evaporative cooling systems. This includes the treatment of cooling water and the consistent combatting of germs harmful to health.

The German Ministry of Health is currently working on reporting/registration requirements for relevant technical installations. In addition, the requirements of VDI 2047-2 will be established in the Federal Pollution Control Act (BImSchG) in the near future, making them mandatory for all operators.

For operators of evaporative cooling systems, the following measures, among other things, are imperative for complying with Directive VDI 2047-2: 

 

  • Drawing up of risk assessments and operating manuals
  • Internal 14-day hygiene controls
  • Regular microbiological testing by accredited laboratories. This should be carried out on a quarterly basis by trained samplers
  • Plans of action in the event of limit values being exceeded

Our accredited laboratory tests and assesses your cooling water for the required microbiological parameters. Our qualified samplers are at your disposal for the sampling process. We assist you in drawing up VDI-compliant risk assessments and develop action plans with you to provide for specific handling instructions in the event of an increase in microbial contamination.

Compressed air inspections in food companies

Current food safety standards (e.g. IFS/BRC) stipulate that the compressed air used may not represent any risk to food safety.

Current food safety standards (e.g. IFS/BRC) stipulate that the compressed air used may not represent any risk to food safety. Microbiological contaminants could, for example, negatively affect food safety. The consequence of this requirement is that the quality of the compressed air has to be examined, controlled and monitored as part of a risk analysis procedure. This is particularly important when the compressed air comes into direct contact with the food product or with plant components and primary packaging which themselves come into contact with the product.

We will gladly assist you in this area with our specialist expertise to ensure that you meet your commitment to the current standards and fulfil your responsibility towards consumers.

 

Please do not hesitate to contact us and let us know what advice and services you require.
