title: [The presence of nortestosterone in edible parts from non-castrated male pigs].
abstract: Nortestosterone is a major growth-promoting agent in Europe which is often used illegally in various species of meat animal. Recent studies showed that this compound was also present in the urine of young male pigs (boars) to which nortestosterone had not been administered. To determine to which extent nortestosterone may also be present in liver and muscle tissues, samples of the urine, bile, liver and muscle of twenty five boars were analysed. The mean and highest concentrations, detected respectively in muscle were 1.1 and 13 micrograms/kg and were 23 and 200 micrograms/kg in liver. The corresponding concentrations in urine were 55 and 132 micrograms/l and 88 and 212 micrograms/l in bile.
