Steps for Treatment, Control and Elimination of Swine Dysentery

Publish Date: 06/13/2022

Swine dysentery (SD or bloody scours), once one of the most expensive swine diseases, largely disappeared in North America in the 1990’s with three site production and improved hygiene, among other changes in swine industry structure. However, since the early 2000s, SD has re-emerged in swine operations in portions of the U.S. and several Canadian provinces. SD is an intestinal bacterial disease that is very expensive to treat and control medically. It is very difficult to completely eliminate once pigs and facilities are contaminated. SD can be spread by infected swine, rodents and other animals in contact with infected swine as well as any fecal material on equipment or clothing. Biosecurity practices are effective at reducing the exposure risks and, when properly implemented, will prevent or slow the spread of this disease (and other diseases) between farms. Your swine veterinarian can assist you in creating a biosecurity plan to prevent introduction to your herd as well as accurate diagnosis should clinical signs of SD be suspected. For more information on how to recognize SD, see the Pork Information Gateway’s Factsheet, “ Swine Dysentery (Bloody Scours); Recognition and Awareness, Diagnosis, Transmission and Clinical Signs”.
