Salicylate level: Low Salicylates, levels at 1.00-2.49 mg/kg

Notes from Low-Sal-Life: Can be derived from MANY sources like citrus. Aspergillus niger (fungus) is the main producer and can be fed a sugar solution from just about anything, but it is usually corn, wheat, or sugar. *RPAH’s lowest level is low (there’s no negligible) and includes levels for both amines and salicylates.
