Ractopamine is fed to American livestock in order to promote lean meat. Currently, it is fed to about 60 to 80 percent of the pigs in America and as a result, there have been numerous reports of dead and sickened pigs. No other livestock drug has caused such high numbers of death and illness according to an investigation by the Food and Drug Administration (FDA).
Since the drug was introduced, over 218,000 pigs on ractopamine have been reported to show very adverse effects. Since March 2011, the drug has caused the majority of problems in pigs even though other livestock animals are on the drug. Pigs are suffering from hyperactivity, trembling, broken limbs, the inability to walk, and death. These results were gathered from a FDA report that was released under a Freedom of Information Act request. Even though these disturbing things are happening to the livestock, the FDA says the data can’t determine that the drug caused these effects.
