South Korea is to declare itself free of bird flu later this week as it has not reported any confirmed cases of the virus for the past three months, the government said Wednesday.

The declaration slated for Thursday is in accordance with guidelines set by the World Organization for Animal Health and follows detailed tests conducted on 11,738 poultry farms throughout the country in the past three months, the Ministry for Food, Agriculture and Rural Affairs said.

"We've met the OIE requirements to declare ourselves avian influenza (AI) free. We will technically become a bird flu-free country as of Thursday," the ministry said in a release.

More than three months has passed without any additional confirmed cases since April 7 when the last culling, decontamination and burying of birds confirmed or suspected of having been infected with bird flu took place. The final outbreaks were last reported on the western outskirts of Seoul on April 5.
