On 6 July 2012, the international reference standard Codex Alimentarius Commission narrowly approved the adoption of a maximum residue limit (MRL) of 10 parts per billion (ppb) for muscle cuts of beef and pork. Setting any limit was a controversial move. Countries with major meat export markets had been lobbying for the establishment of such a standard for several years to use it as leverage to erode individual national-level bans in World Trade Organization disputes. Consumers International, a world federation of consumer groups that represents 220 consumer organizations in 115 countries, strongly opposed the move.
