While researchers and scientists investigate the cause of our diabetes, obesity, asthma and ADHD epidemics, they should ask why the FDA approved a livestock drug banned in 160 nations and responsible for hyperactivity, muscle breakdown and 10 percent mortality in pigs, according to angry farmers who phoned the manufacturer.

The beta agonist ractopamine, a repartitioning agent that increases protein synthesis, was recruited for livestock use when researchers found the drug, used in asthma, made mice more muscular says Beef magazine.

But unlike the growth promoting antibiotics and hormones used in livestock which are withdrawn as the animal nears slaughter, ractopamine is started as the animal nears slaughter.

As much as twenty percent of Paylean, given to pigs for their last 28 days, Optaflexx, given to cattle their last 28 to 42 days and Tomax, given to turkeys their last 7 to 14 days, remains in consumer meat says author and well known veterinarian Michael W. Fox.

Though banned in Europe, Taiwan and China–more than 1,700 people were “poisoned” from eating Paylean-fed pigs since 1998 says the Sichuan Pork Trade Chamber of Commerce– ractopamine is used in 45 percent of US pigs and 30 percent of ration-fed cattle says Elanco Animal Health which manufactures all three products.

How does a drug marked, “Not for use in humans. Individuals with cardiovascular disease should exercise special caution to avoid exposure. Use protective clothing, impervious gloves, protective eye wear, and a NIOSH-approved dust mask” become “safe” in human food? With no washout period?

The same way Elanco’s other two blockbusters, Stilbosol (diethylstilbestrol or DES), now withdrawn, and Posilac or bovine growth hormone (rBST), bought from Monsanto in 2008, became part of the nation’s food supply: shameless corporate lobbying. A third of meetings on the Food Safety and Inspection Service’s public calendar in January 2009 were with Elanco, a division of Eli Lilly–or about ractopamine.
