How to request marine biotoxin testing for shellfish

New request process

Canadian businesses and organizations can request marine biotoxin testing for shellfish from the Canadian Food Inspection Agency (CFIA) laboratories. The Dartmouth, Longueuil and Burnaby laboratories can test for paralytic shellfish toxin, amnesic shellfish toxin, and diarrhetic shellfish toxin. Currently, the CFIA has the only ISO/IEC 17025 accredited laboratories in Canada with marine biotoxin testing methods within their scope of accreditation.
