Abstract: 

During a routine inspection on a pig farm, nortestosterone was found in faecal samples. An intersexual pig held responsible for this finding was slaughtered and further investigated anatomically, histologically and chemically. Macroscopic inspection revealed a mainly female reproductive tract consisting of a vagina, a uterus and on the left side a normal ovary and uterine tube. However, on the right side a hypoplastic testis with an epididymis was found together with a well developed plexus pampiniformis-like structure. Histologically no spermatozoa were found in this testis, but Leydig cells were numerous. Chemical analysis showed the presence of 17--nortestosterone in the urine, fat, kidney and testicular tissue, as well as the precursor noradrenostenedione in the urine, kidney and testis. As intersexuality is a frequent phenomenon in pigs, veterinarians who are responsible for food safety must be aware of this problem which interferes with the inspection on hormonal products in meat.
