Isn't it still free trade having to comply with local regulation? As long as those regulations treats foreign companies/products the same as local ones, of cause. Import taxes or valuing domestic production/owners are not, but i don't see a problem with requiring food not to contain toxic stuff, no matter what country it comes from.
