BAV Institute – Specialists in the Detection of Listeria monocytogenes!
Food contaminated with Listeria monocytogenes has increasingly been the cause of serious foodborne illnesses and recalls in recent years. In crisis situations, quick and reliable results are an important tool for making timely decisions.
The BAV Institute is happy to assist you with all matters related to Listeria testing.
We can support you with the following tests, among others:
- Comparison of Listeria isolates to determine the origin of the strains in positive findings (e.g., do the Listeria in the final product come from a raw material or from the environment?)
- Challenge or stress tests with Listeria monocytogenes
- Other rapid methods for food or environmental samples in 24h or 48h
- Rapid method for the quantitative detection of Listeria monocytogenes in 6h: Tentaspeed L.Mono
Previous testing methods can provide information about contamination with Listeria
monocytogenes in food after approximately 20 to 24 hours at the earliest. The BAV INSTITUTE has developed a rapid method for the direct detection of Listeria spp. and Listeria monocytogenes within 6h in food. This offers the fastest testing method worldwide to quantify Listeria monocytogenes .
We provide you with fast and reliable results.

What are bacteria of the Bacillus cereus group?
Bacillus cereus is the eponymous representative of the so-called B. cereus group. This currently includes 17 recognized, closely related species, which can only be differentiated from each other through very complex laboratory tests. These include the species described up to 2016: B. cereus (sensu stricto (s.s.)), B. thuringiensis, B. cytotoxicus, B. toyonensis, B. wiedmannii, B. anthracis, B. mycoides, and B. pseudomycoides. Additionally, nine more species were described by Liu et al. (2017): B. paranthracis, B. pacificus, B. tropicus, B. albus, B. mobilis, B. luti, B. proteolyticus, B. nitratireducens, and B. paramycoides.
The new species can currently only be differentiated from the established species of the B. cereus group through whole-genome sequencing methods. Beyond the actual species description, there is little data on these new representatives.
In our laboratory, we regularly conduct tests for presumptive B. cereus and other pathogenic microorganisms. We provide you with fast and reliable results.
