From: Precautionary labelling of foods for allergen content: are we ready for a global framework?
Prevalence of allergen cross-contamination in prepacked foods with PAL. (* Note: Zurzolo et al. also assessed products for milk, egg, hazelnut and soya; these allergens were not detected in any product [45]. The higher rates of allergen detection in surveys by Crotty et al. [48] and Pele et al. [49] are most likely due to the food products included: dark chocolate and cookie biscuits/chocolate respectively).
