A total of one hundred and eighty (180) samples of canned fish comprising twenty-eight brands of mackerel, twenty-five brands of sardines, two brands of pilchards and five brands of tuna were purchased from retail outlets in Kumasi in Ghana. Samples were transported to the laboratory, coded for easy identification and then stored in clean dry place until time for preparation. For each canned fish sample, the fish sauce was carefully drained, the content homogenized and a portion was taken for chemical analysis.Most of the fish sauce consisted of tomato, water and salt; and in some cases vegetable oil and spices.
