MERCADO – microbiological criteria database

Go to MERCADO or for more information or find out how to subscribe email our Information team or call +44(0)1386 842000

This Campden BRI Microbiological Criteria Database (MERCADO) contains published microbiological criteria for foodstuffs compiled from a variety of sources and updated on an ad hoc basis. We have developed this database to enable users to conveniently and quickly search for relevant information which is provided without liability for its application and use.


It is important to note that accurately assessing global regulatory microbiological criteria is a complex task as reference data is regularly updated. We recommend that MERCADO users contact Campden BRI’s Regulatory Team at regulatoryadvice@campdenbri.co.uk to ensure that they have the most up to date and relevant information for their foodstuff(s).


This database has been written to be used alongside the revised Guideline 52, which details the importance and development of microbiological criteria including: guidelines; specifications; and standards. We would strongly advise users to read this Guideline before interrogating the database.


The database will be updated on a regular basis and users are encouraged to provide details of any information that they are aware of, but is currently not included.


The user can access the database for an annual subscription, which includes a pdf version of Guideline 52. (Hard copies are available for purchase separately if required.)


NB, It is assumed that the user of MERCADO has a knowledge of microbiology to enable them to interpret the output from the database. If the user is not comfortable to operate the database themselves, Campden BRI offer a service to help with this.
