The Longueuil Laboratory
Canadian Food Inspection Agency
The Canadian Food Inspection Agency (CFIA) is responsible for delivering federally mandated programs for food inspection, plant and animal health. The Agency relies on high-quality, timely and relevant science as the basis of its program design and regulatory decision-making. Scientific activities inform the Agency's understanding of risks, provide evidence for developing mitigation measures, and confirm the effectiveness of these measures.
CFIA scientific activities include laboratory testing, research, surveillance, test method development, risk assessments and expert scientific advice. Agency scientists maintain strong partnerships with universities, industry, and federal, provincial and international counterparts to effectively carry out the CFIA's mandate.
The Longueuil Laboratory
The Longueuil Laboratory has analytical expertise in several areas related to food safety and consumer protection. The laboratory is the national reference and research centre for food allergens. It is the only CFIA laboratory with expertise in nutritional analysis to verify compliance of nutrition information in accordance with Canada's food labelling laws. The laboratory also works in the fields of nutritional composition, dyes and marine toxins.
What we do
- Food allergens: analysis of imported and domestic food, including consumer complaint samples using enzyme-linked immuneo-sorbent assays (ELISA)
- Colours in food: analysis of regulated food colours, illegal dyes and natural colours in foods by high-performance liquid chromatography
- Nutritional labelling: verification of the nutrients, vitamins, minerals, lipids, carbohydrates and protein content declared in the nutrition facts table
- Food composition of dairy products: analysis of moisture, fat and other parameters by instrumental and classic chemistry methods
- Marine toxins: using high-performance liquid chromatography to detect amnesic (domoic acid) and paralytic shellfish toxins (PSP)
Research and development
- Development and implementation of new chemistry methods to fulfill the laboratory's analytical mandate.
- Evaluation, development and validation of analytical methods (ELISA, PCR, and mass spectrometry to detect allergens in processed food.
- Scientific advice to operational and inspection staff at the CFIA, and sharing technical expertise with private labs, regulated parties and other stakeholders.
- Quality audits of private food laboratories for the ISO/IEC/ 17025 standard.
All CFIA laboratories have demonstrated conformance to ISO/IEC 17025, General requirements for the competence of testing and calibration laboratories. The Standards Council of Canada evaluates our laboratories against this international standard, as a formal verification of the CFIA's capability to produce accurate and reliable results, within our accredited scope of testing. The results are supported by the development, validation and implementation of scientific methods, conducted by highly qualified personnel, using reliable products, services, and equipment, in a quality controlled environment. Participation in international proficiency testing programs further demonstrates that our testing is comparable to laboratories across Canada and around the world.
