Dear NRL representative,
The National Food Agency Sweden (NFA) which is the EU Reference Laboratory (EURL) for Foodborne Viruses would like to invite you to participate in two upcoming proficiency testing schemes.
PT schemes are designed for qualitative detection of norovirus GI, GII and HAV in raspberries based on ISO 15216-2 and quantification of norovirus GI, GII and HAV in oysters based on ISO 15216-1. Please notice that the Standard Operating Procedure (SOP) for quantification of viruses in oysters will be provided in due time.
Inoculated viruses are cultured hepatitis A virus strain HM 175/18f and norovirus positive faecal samples.
Dispatches are planned for 7 May 2019 for raspberry and 5 November 2019 for oyster samples. Participants should submit the results latest 24 May and 22 November respectively.
According to ISO 15216, it is required to use EC-RNA and a process control virus in order to evaluate the extraction efficiency and inhibition. We highly recommend you to follow your laboratory procedure. However, if you have no access to EC-RNA and mengovirus we can provide them to you. Remember that mengovirus is a GMO and you should have procedures and permissions in the laboratory to handle GMOs.
Final reports will be prepared and communicated with the participating laboratories and SANTE Health and Food Safety.
If you wish to participate, please fill in the registration form below no later than 14 February.
Please notice that the distribution is provided to NRLs for foodborne viruses free of charge.
