Allergen-Shield Brazil nut is a highly specific sandwich enzyme-linked immunosorbent assay (ELISA) designed for the rapid and reliable determination of Brazil nut residues in food products labeled as Brazil nut-free. When paired with the optional Surface Swabbing Kit, the method extends beyond product testing to include environmental monitoring, allowing users to easily assess surface contamination and support robust cleaning validation procedures.
