EU member states put chlorine in their water supply, too, but chlorine itself was never the problem. Chlorine washing can be used to hide problems further up the supply chain, so if vinegar washing enables the same, it should also be disallowed.

Not all states do, atleast in my region, there is no requirement to clean water with chlorine once it comes from the water table other than if a farmer screws up their schedules.
