Pet Food Allergen
Pea Protein Allergy in Dogs and Cats
Pea protein is a concentrated protein fraction extracted from yellow or green peas, widely used to boost crude protein on labels of grain-free formulas without increasing animal-ingredient cost. Separately from classic IgE allergy, pea-heavy diets were identified by the FDA as a recurring pattern in the ongoing DCM (dilated cardiomyopathy) investigation.
Prevalence
Not yet documented as a frequent primary allergen. Gut-level reactions reported with rising frequency as grain-free exposure has grown since 2012. FDA DCM investigation (2018-2022) tracked 1,382 cases, 93% containing peas or lentils.
