Resorcylic Acid Lactones, including zeranol, anabolics listed in the group A4 of Directive 96/23/EC, are banned in Europe for use in animals since 1985. Zeranol, after administration to animals, is metabolized to taleranol and zearalanone. It can also naturally occur in the urine due to conversion of zearalenone that may be present in animal feed. In 2010-2017, in Poland, 7746 animal samples were tested for zeranol residues within the official monitoring program. In 13, zeranol was detected after screening...
