The Office of the US Trade Representative (USTR) has announced that the Obama administration will take the first steps in reinstating trade action against the EU for banning US hormone-treated beef from sale in the EU.This reignites a decades-old dispute on banning US hormone-treated beef in which the WTO ruled against the EU in 1998 as there was no scientific evidence to support the ban. The US was authorised by the WTO to introduce sanctions of additional tariffs against EU products coming into the US.
