Detailed causes

Swine dysentery is still a problem in some herds and in some countries, but it can be treated, controlled and eliminated. Improved methods of diagnosis have allowed increasingly sophisticated certification for herds free from infection. Plus, strict biosecurity can be supplemented in many countries by supplies of dysentery-free breeding stock to ensure that production is not interrupted by the disease.
