Iodine levels in brands of salt on the markets of Accra, Ghana

摘要

Results: The iodine content (in ppm) at retail, recorded for the samples are as follows: Sample A (25.4), B (51.8), C (52.9), D (45.5), E (25.4), F (75.1), G (28.6), H (0), I (13.7), J (34.9) and K (16.9). No iodine was observed in the raw-pellet salt (sample H) crystallized directly from sea water, in contrast to the long-held belief that it contains nat- ural iodine. Furthermore, all samples analyzed did not meet the concentration levels indicated on their labels and did not meet the Ghana Standard Authority’s standard.
