Risk-based approaches for food allergens offer a path forward for both allergen management and precautionary allergen labeling decision-making. After many years of research, a clearer picture has emerged of the population-level, threshold-dose distributions for major food allergens using data generated in double-blind, placebo-controlled food challenge studies. If the food allergen management field is headed for a shift toward quantitative, risk-based management strategies, however, then several method considerations and important data gaps must be addressed.
Class 1 recalls are defined as situations where there is a reasonable probability that the use of or exposure to a food product will cause serious adverse health consequences or death to humans. Residues of most of the so-called "Big 8" (and soon-to-be "Big 9," with the recent addition of sesame seeds) allergenic foods are considered as a basis for Class 1 recalls. While food allergen recalls are unwelcome, potentially valuable lessons can be learned from these unfortunate events. Good manufacturing practices (GMPs) have evolved from corrective actions taken to prevent allergen recalls.
