RESUMO
A Dutch farmer with beef cattle and suckling calves noticed one of the calves suffering from diarrhoea and observed large white worms near the perineum. In the faeces of this calf, eggs of Toxocara vitulorum were found. The majority of the cows in the herd were of the Piemontese breed previously imported from southern France. Treatment with albendazole was successful. Two other calves had positive faecal egg counts. One month after treatment of these calves with doramectin, no eggs were found. To prevent further infections on the farm and dissemination of this uncommon infection to other farms, the farmer decided to have all his cattle slaughtered.

A 2-month-old suckling calf had complaints of diarrhea and roundworms near the perineum. Faecal examination showed the presence of a high number of roundworm eggs of Toxocara vitulorum. The calf was a daughter of a Piemontese cow, born on the farm, but with a grandmother imported from France. This case describes the measures taken on the farm to prevent clinical problems and dissemination of the infection to other farms.
