Is cut flower food harmful for the environment?

In general safety precautions and danger symbols must be printed on the label of any product that contains certain ingredients that exceed pre-determined quantities. For Chrysal cut flower foods, used by consumers, no such safety precautions and danger symbols are required. However ‘Keep out of reach of children’ is printed on the label as a precaution, though not obligatory. This minimum type of labelling is sufficient for all non-toxic non-food products. No other labelling is required for Chrysal cut flower food consumer packs. This also means that pouring the left-over vase water down the drain is not a problem. The drainage system is generally connected to water treatment plants which will purify this discarded water.
