There are many practices that can be employed to assist in the reduction of allergen cross-contact, including the appropriate use of area and equipment segregation. However, if separate processing areas and equipment are not possible, cleaning becomes the major method of allergen control on shared production lines. As a prerequisite controlling a hazard, and as required by best practices and GFSI auditing standards, such cleaning requires validation and subsequent monitoring and verification. This presentation provides guidance on allergen control through the application of appropriate validation, verification, and monitoring.
