Toxicological Risk Assessment (TRA) is a comprehensive safety evaluation report for a specific ingredient or contaminant in a product. TRA is a detailed scientific assessment report prepared by an expert toxicologist based on sound scientific knowledge on all the available information/data about the specific ingredient within the context of the nature of the product, its dosage/concentration, and exposure scenario.
