Consumer Advice ​

Chlorine is used in the food industry mainly as a processing aid, for flour bleaching and water sanitisation. Any chlorine used this way largely dissipates and does not remain in the final food product. When used according to food regulations it is safe, and consumers need not worry about residues in everyday food.
