Studies on the salicylic content of foods are sparse and have produced distinctly different results, creating controversy.  Possible causes for the discrepancies include uncontrolled and often unreported factors such as cultivation area, crop species, and harvest methods, as well as inherent issues with the studies such as poor extraction and measurement procedures and limited or low-accuracy equipment. A recent study using best practice measurement methodology significantly reduced intra-sample measurement variability but has not yet been replicated or extended.
