"The move from “ppm matrix” to “ppm protein” is a major milestone in allergen management — providing greater accuracy, improved risk assessment, and enhanced consumer safety. Driven by programs like VITAL and backed by evolving detection technologies, this shift reflects a deeper scientific understanding of what truly causes allergic reactions. By focusing on protein, the immunologically relevant component, food manufacturers and regulators can establish more reliable thresholds, enable more consistent test methods, and ultimately protect allergic consumers with greater precision.

For food safety professionals, quality managers, and production managers, the transition may require some initial adjustments to testing protocols and documentation. However, the long-term benefits in accuracy, regulatory compliance, and consumer trust make “ppm protein” the clear path forward in allergen risk management."
