Water as a raw material for making ice cubes should be able to see the requirements contained in SNI 01-3553-2006 Bottled Drinking Water. To note, this SNI requires quality, among others, odorless, dissolved substances max. 500mg/l, organic matter 1.0 mg/l, chloride max. 250 mg/l, sulfate max. 200 mg/l, and ammonium max. 0.15 mg/l. Obviously, ice cubes whose raw water contains a lot of bacteria should not be drunk. it is impossible for ice cubes to be heated first to kill bacteria because it violates its function to cool drinking water. it is feared if it turns out that the ice cubes produced for cooling fish are used for drinking water consumption.
