Japanese officials have culled 753 pigs in Saitama Prefecture north of Tokyo after detecting an outbreak of swine fever, according to reports by the Yomiuri newspaper.
The Yomiuri said that the cull, which took place on Saturday, was necessary after it was determined that pigs raised in the prefecture for shipment to central Japan were infected.
Saitama also decided to halt shipments from two other pig farms in the area of the outbreak, the Yomiuri said.
Officials from the Saitama Prefecture government were not immediately available to comment.
Last year, Japan confirmed the first outbreak of swine flu in 26 years in the country. The fever was found in a farm in the Gifu Prefecture, central Japan.
