Microbiological Analysis

We offer comprehensive microbiological testing services including microbial counts and qualitative and quantitative analyses such as inhibitor tests, shelf-life studies and the examination for antibiotic-resistant germs. We test for the plate count for different germs (including antibiotic-resistant germs like MRSA) as well as the presence. We have the capability to store samples for a given time under specified temperature (Storage/shelf life test) and also can do challenge test incubating samples with germs in order to check their capabilities to spawn under specific conditions.

Drinking Water Testing

Our laboratory is a certified drinking water examination site in accordance with Article 15.4 of the German Drinking Water Ordinance (TrinkwV) 2001. We also provide testing of bottled water and beverage quality, pharmaceutical water and wastewater as well as auditing of water used in dental practices.

Microbial Count

We accurately determine the pathogenic and other germ content in your food product according to Article 64 of the German Food and Feed Code (LFGB) and applicable ISO standards.  This includes the total number of germs as well as the number of spoilage agents and pathogenic germs within your product. We can also customize the microbial spectrum for a specific product class or your issue.

Our spectrum testing includes:

  • Determination of the total number of aerobic mesophilic germs
  • Bacillus cereus
  • Campylobacter
  • Clostridia
  • E. coli and enterohemorrhagic Escherichia coli (EHEC)
  • Enterobacteriaceae
  • Yeasts
  • Listeria (including Listeria monocytogenes)
  • Lactic acid bacteria
  • Pseudomonads
  • Salmonellae
  • Molds
  • Staphylococci (including Staphylococcus aureus)
  • Yersinia enterocolitica
Identification of Microorganisms

On request, we can determine the family and type of germs through biochemical, molecular biological or microscopic tests.

Antibiotic Resistance

The frequent use of antibiotics in livestock industry and aquaculture leads to increased resistance of bacteria to these antibiotics, which is a potential hazard for consumers.

We can test your samples for methicillin-resistant Staphylococcus aureus (MRSA) or extended-spectrum beta-lactamase (ESBL)-producing bacteria.

Inhibitor Tests

We examine whether antibacterial substances such as veterinary medications are present in your food products. We can test for antibiotic residue in meat, fish, shrimp and eggs.

Shelf-Life Studies / Challenge Tests

We use challenge tests to examine the growth rate and the tenacity of pathogenic germs in your food product.

For shelf-life studies, we use the same refrigeration units that are standard in food retailing.  Our testing takes place under realistic conditions and allows for reliable prognoses for germ development in the food product.

Biocides / Disinfectants

We examine the effectiveness of chemical disinfectants and antiseptics in accordance with  DIN EN 14885 and the German Veterinary Society (DVG) test guidelines. In addition, we analyze the effectiveness of disinfectants according to DVG test guidelines in the areas of meat production and food products with animal origins, milk area and commercial kitchens.
