Denmark is building a 43-mile fence along its border with Germany to keep out wild pigs that could pose a major risk to the country’s pork industry.
The move, which was authorized by Danish lawmakers in June, is an attempt to prevent the spread of African swine fever. Unlike swine flu, African swine fever doesn't affect humans but it can be deadly for domestic and wild boars, and cause massive losses for farmers.
Work on the fence, which will be up to 5 feet tall, began Monday in Padborg, 136 miles southwest of Copenhagen.
