individuals following a gluten-free diet. Some of these foods
are shown in Table 2, and represent potential products that
could have cross-contaminated starting materials. This list is
not exhaustive and there may be examples more appropriate for
a specific jurisdiction.
Conclusions
Intolerance to gluten (celiac disease) requires the strict
avoidance of gluten sources from wheat, barley, rye, or their
crossbred species. Codex Alimentarius recommends that for a
food to be labeled gluten-free, it must not contain more than
20mg gluten/kg of food. The food allergen analytical community
is endeavouring to create harmonized guidelines for food
allergen ELISA methodologies to help protect food-sensitive
consumers and promote consumer confidence. The guidance
described here reflects a consensus reached, through input
and collaboration, from various allergen analytical experts,
and contains specific recommendations and requirements
for the validation of ELISA methods for the detection and
quantification of gluten proteins in food matrixes. Future work
is planned for the implementation of this guidance document
for the validation of gluten methods and the creation of gluten
reference materials.
