External Quality Control System (EQAS)
Description of EQAS methods
The National Food Institute, Denmark, a WHO Collaborating Centre and one of the coordinating agencies of the Global Foodborne Infections Network, is responsible for conducting the Network's External Quality Assurance System (EQAS) for Salmonella and Shigella serogrouping, serotyping and antimicrobial susceptibility testing. Additionally, the programme includes identification and MIC determination of Campylobacter and identification of an unknown human pathogen. This programme is developed specifically for national reference laboratories in veterinary, food or human health sectors participating in the Global Foodborne Infections Network.
Depending on the extension of participation in EQAS, laboratories receive by mail eight anonymous strains of Salmonella and Shigella, four Campylobacter isolates and one unknown isolates for identicication annually. The strains should be tested by the methods routinely used in the laboratory and the results are then submitted to the WHO Collaborating Centre via a password-protected website – alternatively by regular mail.
Each laboratory participating in the EQAS receives an individual report of its results. Full anonymity is assured. The identity of individual laboratories is not revealed to other Global Foodborne Infections Network laboratories, or to third parties. When the results of each cycle of the EQAS have been evaluated, a final summary report is prepared and distributed to all Global Foodborne Infections Network laboratories as well as made available online on this webpage below.
