Expert Verdict

Bovine milk protein source can trigger Type I (IgE-mediated) allergic reactions in sensitized individuals (up to 8% of children); milk origin declaration required. Hydrolysis reduces but may not eliminate allergenicity—molecular weight control is critical. BSE is not a concern per FDA 21 CFR §700.27.
