The chicken isn't chlorinated, but the reason why it might not be healthy when using chlorination/why the EU banned it is probably not what you think.Are you sure? I thought chlorination was not allowed. Granted, many other pesticides and poor animal husbandry practices probably persist in some (unscrupulous) places, but not chlorination .........I think.
The EU banned it because chlorination is done at the end of processing (in the USA) and the EU believe if it was adooted, businesses may cut corners during the processing because they know the chlorination is being done at the end and therefore it's safe to cut corners / treat chicken in an unsanitary way.
