Food contaminated by microorganisms (bacteria and yeasts), viruses, and protozoa can cause severe disease in humans. There are two categories of foodborne diseases.
Microbiological test procedures for the examination of foods and beverages have been standardized and regulated, but nearly every country has its own regulations. Most of the culture media, additives, dyes, and indicators conform to standard norms like ISO, these products include:
Culture media and base ingredients are conveniently organized by food and beverage application for ease of locating the proper materials.
Visit our Microbial Culture Media and Microbiology Standards webpages for more information.
For simple and fast detection of bacteria, use media with a chromogenic substrate such as Salmon-GAL, X-Gal, and X-glucuronide. Certain enzymes, produced by some bacteria, cleave these substrates, resulting in the different coloration of specific bacteria colonies. This allows us to clearly see the presence of the targeted microorganism, observed as a clearly visible color change. Most chromogenic media is intended for the detection of pathogenic bacteria, including our media for Clostridum perfringens, the first of its kind.
We offer a wide selection of tests and reagents for pathogen detection, identification, and confirmation.

Classical reagents, kit systems, or convenient discs and strips can be used in the identification and confirmation of microorganisms. Based on rapid screening methods like the detection of enzymes with chromogenic substrates, indicators, or complex building reactions, they are faster and easier to use. Also, the sensitivity to certain inhibitory substances can be used to identify organisms.

HybriScan rapid test kits are based on an rRNA sandwich hybridization system which is less expensive and more robust than PCR methods. They are also more accurate (only detects living cells), quicker (time savings of up to 10 days over cultivation-based assays) and can be performed with standard laboratory equipment. These kits can be used for the identification and quantification of spoilage and pathogenic microorganisms in foods and beverages. They are ideal for the comprehensive and reliable routine control of raw materials and concentrate on all production steps, up to the quality check of finished goods.
