The consumption of the offal of non-castrated pigs can lead to the excretion of 19-norandrosterone (NorA) in urine of humans. In doping control, GC/C/IRMS is the method of choice to differentiate between an endogenous or exogenous origin of urinary NorA. In some cases, after the consumption of wild boar offal, the δ13C values of urinary NorA fulfill the criteria of an adverse analytical finding due to differing food sources of boar and consumer. However, consumption of wild boar's offal is not very common in Germany and thus the occurrence of such an analytical finding is unlikely. In contrast, the commerce with wild boar meat has increased in Germany within the last years. Up to 20,000 tons of wild boar meat are annually consumed. In order to probe for the probability of the occurrence of urinary NorA after consumption of wild boar meat, human urine samples were tested following the ingestion of commercially available game. In approximately half of the urine samples, traces of NorA were detected post administration of 200 to 400 g boar meat. The highest urinary concentration was 2.9 ng/ml, and significant amounts were detected up to nine hours after the meal. δ13C values ranged from -18.5 to -23.5 ‰, which would have led to at least two adverse analytical findings if the samples were collected in an anti-doping context. IRMS analysis on German boar tissue samples showed that δ13C values for wild boar's steroids are unpredictable and may vary seasonally.
