Allergen Testing

Food manufacturers are responsible for accurately listing the ingredients of their products on their food labels. Food labels are an important source of information for those individuals with food allergies, sensitivities or intolerances. As part of a robust quality system, testing for allergens lends to your confidence in your product's safety, provides information for label compliance and helps to prevent costly recalls.

The Agriculture & Food Laboratory (AFL), at the University of Guelph offers Enzyme-Linked Immunosorbent Assay (ELISA) tests for all major food allergens. We provide accurate, timely results with the option of RUSH turn-around.

We offer quantitative assays for the following allergens in your raw and finished food products:

  • Brazil nut
  • Buckwheat
