Is yeast an allergen?

Q: Is yeast an allergen?

Standard baker’s yeast, Saccharomyces cerevisiae, is very easily digested by the human body. Furthermore, yeast is not included in the list of products likely to cause allergies or intolerances, subject to mandatory labelling as per European Regulation 1169/2011. With the application of an effective HACCP program, yeast producers can guarantee that yeast is free of allergens. This program notably includes extensive procedures to avoid cross-contamination and ensure traceability and preparation in accordance with Good Manufacturing Practices (GMPs). However, because yeast contains many types of proteins, yeast may be the cause of an allergic reaction in very sensitive individuals, though this is extremely rare.
