"chlorinating them possibly encourages less healthy/ethical methods."
It's not true. The chlorination is a way to prevent pathogens. There are just different methods.
Like the USA uses pasteurized milk but then the milk needs to be refirgeratored on the shelf. While the EU irradiates the milk, but then the milk can be on a shelf with no refrigeration.
Or if you look at car safety standards, there is the US standard, the EU standard, and the Japanese standard. Just different ways of ensuring safety.
You don't want chlorination? sure, but don't think you aren't getting other pathogen preventing methods. That's just a fact of life with industrial agri culture.
So then are the other methods of pathogen preventing also encouraging less ethical/healthy measure? nope.
