For a correct qualification and quantification of residues in matrices, proper handling of samples is required. Improper storage conditions could be a potential risk for the stability of analytes in samples. Reanalysis of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) in milk samples showed an increase of the extractable salicylic acid concentration during storage outside the freezer (e.g., transport). Even within a day, the levels increased and some exceeded the MRL, which could lead to false non-compliant findings for salicylic acid.
