RELATIVE SAFETY OF CLENBUTEROL AND RACTOPAMINE RESIDUES IN EDIBLE TISSUES OF HOGS

摘要

Clenbuterol HCI (Figure 1) gained notoriety as an illegal feed supplement in 1990 when it was reported that residues present in beef caused several human intoxications (1). Since that time, illegal clenbuterol residues have been detected worldwide (2, 3) and additional human intoxications in Europe (4) and Asia (5) have occurred. These incidents led the European Union to ban all beta-agonist use in food animals (3).
