A pathogen is a synonym for a disease-causing microorganism. Food pathogens represent a special form of microbial pathogens, which are picked up and spread through food.
Below a number of pathogens are listed, for which BIOTECON Diagnostics offers suitable foodproof® DNA extraction and real-time PCR detection kits. Many of the pathogen kits have been certified by recognized institutions such as AOAC-RI, MicroVal or NordVal (see licensing options / validations), and thus independently tested for quality and safety.
Foodborne Pathogens Detection Kits
foodproof® Foodborne Detection Kits
Campylobacter are corkscrew-shaped, Gram-negative bacteria. They are often found on raw poultry. Campylobacter jejuni is the most common bacterial cause of gastroenteritis. Infection may even cause nerve damage, such as the autoimmune disorder Guillain-Barré syndrome (GBS).
The foodproof® Campylobacter Quantification Kit is suitable for the quantification of the four thermotolerant Campylobacter species C. jejuni, C. coli, C. lari and C. upsaliensis from poultry or meat rinse water. Additionally, the two most common pathogenic species, C. jejuni and C. coli, can be identified in two separate channels.
The foodproof Clostridium botulinum Detection LyoKit detects all human-relevant toxingenes – types A, B, E and F – in a single multiplex real-time PCR reaction.
The foodproof E. coli and Shigella Detection Kit detects the important species E. coli and the genus Shigella, a group of Gram-negative, facultative anaerobic, rod-shaped bacteria in the family Enterobacteriaceae. Shigella can cause very severe shigellosis or dysentery.
The foodproof STEC Screening LyoKit detects the Shiga toxin genes stx1 and stx2, including the allele stx2f, as well as the adherence-factor intimin gene (eae) in one multiplex real-time PCR reaction. The detection of stx2f is currently not possible using the STEC ISO / TS 13136.
Shiga toxin-producing Escherichia coli (STEC), also known as enterohemorrhagic E. coli (EHEC), or verocytotoxin- or verotoxin-producing E. coli (VTEC), have been linked with severe complications like the hemolytic-uremic syndrome (HUS) in humans.
Some STEC serotypes are linked to severe complications more often than others:
- E. coli O157, accounting for 50 to 80 % of human STEC infections
- The „Big Six“ O26, O45, O103, O111, O121 and O145, responsible for 70-75 % non-O157 infections
- E. coli O104, that caused a serious outbreak in Germany in 2011
STEC are most commonly transmitted through raw ground beef, raw or inadequately pasteurized milk, sprouts and vegetables. The foodproof® STEC Identification LyoKit can detect and identify the eight most important STEC serotypes O26, O45, O103, O104, O111, O121, O145 and O157 in just one single PCR test. The completely new and unique assay design enables melting curve analysis with sequence specific 5`Nuclease-probes, whereby highest specificity is achieved.
The foodproof® STEC Identification LyoKit is in accordance with ISO/TS 13136 and USDA-FSIS method MLG 5B.
The foodproof Enterobacteriaceae plus Cronobacter Detection Kit combines these two parameters, making it the only kit on the market that complies with the statutory requirements in a single test.
To detect only the single parameters you can find our foodproof Listeria Genus or Listeria monocytogenes Detection LyoKits in our portfolio.
Salmonella are rod-shaped, Gram-negative bacteria. They are pooled in the genus Salmonella, and assigned to the family Enterobacteriaceae. They cause disease in humans and animals, including typhoid fever and diarrhea. Infection commonly occurs through ingestion of contaminated food, typically eggs and poultry.

In contrast to traditional methods, which are time consuming and error-prone, the foodproof Vibrio Detection LyoKit offers high sensitivity, 100% specificity and results in less than 24 hours. In just one single test, the foodproof Vibrio Detection LyoKit detects and discriminates between Vibrio parahaemolyticus, Vibrio vulnificus and Vibrio cholerae. Additionally, the pathogenicity factors ctx, tdh, trh1 and trh2 can be detected and individually identified by melting curve analysis using sequence specific 5`Nuclease-probes.
The foodproof Vibrio Detection LyoKit is compatible with all relevant raw and processed seafood matrices such as whole squid, raw oysters or smoked salmon as well as other matrices. The rapid and easy sample preparation includes a live/dead discrimination step using Reagent D, eliminating false-positive results from dead Vibrio.
In contrast to traditional methods, which are time consuming and error-prone, the foodproof Yersinia enterocolitica plus Yersinia pseudotuberculosis Detection Kit offers high sensitivity, 100 % specificity and results in only 24 hours.
In just one single test, the kit detects and discriminates between Yersinia enterocolitica and Yersinia pseudotuberculosis.
The foodproof Yersinia enterocolitica plus Yersinia pseudotuberculosis Detection Kit is compatible with all relevant matrices such as pork minced meat, other raw meat and sausages, vegetables as well as other matrices like surface water samples.
A rapid and easy DNA extraction with the foodproof StarPrep One Kit is possible.
Staphylococcus aureus is found almost everywhere in nature, including human skin and in the upper respiratory tract. Usually it does not cause any disease symptoms. However, Staphylococcus aureus is one of the most important pathogens in hospital-acquired (nosocomial) infections. One transmission route is through food contaminated by human contact.
Bacillus cereus is a toxin-forming pathogen in the food industry. Its heat-stable spores germinate in hot held foods, which is why there is particularly an increased risk in places with catered food. The spores of B. cereus also survive drying processes and can be found in dried products, such as spices or dried mushrooms.
Once in the intestine, food contaminated with C. perfringens is considered harmful due to the build of enterotoxins it produces. This bacterium is an anaerobic spore former, proliferating under conditions without oxygen, such as canned food or within a piece of meat. C. perfringens forms environmentally resistant spores that are not killed by boiling and other cooking processes.
