What evidence do you have that chlorine, as used in a fish processing plant
in the concentrations likely to be used in a fish processing plant,
produces 'questionable by-products'? Would the risks to consumers from
these questionable products be more than the risks to health of the factory
personnel of using ozone in the plants?
