that represents 220 consumer organizations in 115 countries, strongly opposed the move. Ractopamine use in food animals is banned in over 160 countries. European Union Ractopamine has not been allowed in the European Union, based on the 2009 EU's Food Safety Authority's opinion on its safety evaluation, which concluded that available data were insufficient to derive a maximum residue limit as a 'safe residue level for human consumption'. The uncertainty was particularly great for people who might be thought to be more susceptible than most to an increase in β adrenergic stimulation from consuming the additive, such as children or people with cardiovascular disease, and that simply increasing the "uncertainty factor" built into the calculation as a safety factor would rapidly become arbitrary. Canada, United States, Mexico Ractopamine use as a feed additive is authorized in the United States, Canada, and Mexico. In the US, ractopamine is allowed to be used at a feed concentration of 5–20 mg/kg feed for finishing pigs and in dosages of 5–10 mg/kg feed for finishing pigs heavier than 109 kg. The maximum residue limit for ractopamine for meat in the USA is 50 parts per billion (ppb), or five times the standard set by the Codex Alimentarius. Ractopamine was approved by the FDA in 1999 for use in swine, in 2003 for use in cattle, and in 2008 for use in turkeys. In 2015, the USDA approved of a new label, "No ractopamine — a beta-agonist growth promotant" to be used. The Canadian Food Inspection Agency (CFIA) maintains the Canadian Ractopamine-Free Pork Certification Program (CRFPCP) so that Canadian exports to Asian countries are not disallowed by their authorities. Hundreds of commercial feed facilities, including some from overseas, are enrolled in the CRFPCP, a programme that is essentially based on self-certification and backed up by a randomized testing policy. Currently, the label for USDA organic means no synthetic compounds can be used other than those on the list of allowed synthetics; therefore, ractopamine would not be allowed in certified organic production. For Canadian domestic consumption of non-CRFPCP pork, ractopamine hydrochloride is permitted to be sold over the counter with applications in meal or pellet feed for finishing barrows and gilts (up to 10 mg/kg for last six weeks), confined finishing cattle (up to 30 mg/kg for last 42 days), and finishing heavy turkeys (up to 9 mg/kg for 14 days).
