outbreak, not far from the city of Osijek, is the worst so far in the country, the ministry added.
The farm is not far from the spot where CSF was found in October, according to the ministry. At that time 3,600 pigs were slaughtered.
Veterinary officials say that weak bio-security measures and uncontrolled transport of the animals from the previously contaminated farm caused the new infection.
CSF broke out in Croatia in July for the first time since 2003. From that moment on, over 6,000 pigs have been slaughtered.
