DEFENCE and veterinary personnel say every animal in the KwaZulu-Natal province might have to be put down to contain the spread of foot-and-mouth disease. Veterinarians slaughtered more than 4000 animals in September and October, but the disease, believed to have been imported in swill bought from a ship in Durban harbour, has spread from the original pig farm infected. Officials said up to 7000 cattle and 2000 goats could be slaughtered this week. – AFP
