There are some very good arguments for washing chicken with Chlorine solutions. The downside is that if it is assumed that the chlorine treatment is all embracing, then standards of cleanliness elsewhere in the process may not be as thoroughly policed.
"Under current EU rules, the chlorine wash is classed as a processing aid rather than an ingredient and so wouldn’t have to be declared on the packaging." The European Food Safety Authority has found no conclusive evidence that antimicrobial chemicals used in food processing contribute to antibiotic resistance.
It is just another bleat from remainers. Perhaps we are all supposed to become veggietwats like corbyn of the allotment.

It seems a specious argument to me.
I would prefer more policing of contaminated meat sold to unwitting consumers and the prevention of the substitution of hoss for prime beef.
