Intended use:
RIDA®STAMP Pseudomonas is an agar for the determination of total numbers ofPseudomonas spp. on surfaces in the production environment and on solid foods. The RIDA®STAMP plates consist of a special 10 cm2 petri dish containing organism specific agar which is protruding above the surface of the plate in order to allow direct contact with the selected flat surface or solid food sample.
Regular sampling on cleaned and sanitised surfaces will lead to a complete quantitative hygiene monitoring process. Repeated controls will play a part in contributing to good workplace hygiene according to the concept of HACCP and support GMP guidelines.
General Information:
Pseudomonads are Gram-negative, rod-shaped bacteria which are ubiquitous in waters and soils as well as on plants and animals. They are able to form biofilms, are often resistant against antibiotics and are well known as opportunistic pathogens (e.g. P. aeruginosa). Due to their flexible metabolism Pseudomonads are able to adapt to various environmental conditions. Contamination of fresh or natural foods often lead to early spoilage and thus they should be avoided.
The vast majority of all Pseudomonas species forms round, dome-shaped or compressed colonies on the surface of RIDA®STAMP Pseudomonas. The colonies show yellow-greenish fluorescence.
