UK cattle test positive for Enzootic bovine leukosis

Cattle fed on imported colostrum substitute have tested positive for enzootic bovine leukosis in the UK.

DEFRA tests on three UK farms found calves had picked up the disease from Calf's Choice Total, a Canadian-produced colostrum which is distributed by Alta UK.

DEFRA said there was no direct animal health risk from using the product, and the affected herds had been placed under movement restriction.
