Rapid tests from Neogen® for growth promoters, including ractopamine and clenbuterol, can screen meat and tissue samples in the parts per billion.
Ractopamine is a beta-agonist drug added to feed to promote lean muscle in animals raised for meat. While many countries allow the use of ractopamine within specified limits, including the United States, regulatory agencies in other countries have banned residues of the drug, including those in the European Union, Russia, and China. Neogen’s Ractopamine Lateral Flow Device (LFD) tests are intended to screen cattle and swine samples, and swine and turkey feed samples for the presence of ractopamine. The tests are one-step screening tests that easily detect the presence of ractopamine at set levels. The ractopamine screening test for swine screens at 2.5 parts per billion (ppb); the test for cattle screens at 1 ppb; and the test for swine and turkey feed screens at 0.5 or 4 parts per million. Neogen also offers its Ractopamine Microwell ELISA for cattle and swine, urine and tissue testing, which is approved by USDA.
