There is no one magic solution to prevent a hog farm from a PEDV break. A comprehensive approach is needed for preventing and fighting against the virus, especially with the multiple ways pigs can become infected.
Look at all ways the virus could get into an operation. These can include:
- Transportation. Make sure trucks are clean and incoming animals are disease-free. Make sure feed and propane trucks, which may have visited another farm first, are following a biosecurity hierarchy, such as visiting sow farms before finishing farms. Give all employees the authority to reject trucks that are not clean.
- Employees. Help employees understand that biosecurity starts before the farm. It requires constant awareness. Employees should minimize travel to other farms or areas where livestock are kept. Establish clean-dirty lines so any exposure stops at the door. Empower employees to help identify risks for farm safety.
- Supplies. Have protocols for incoming supplies, such as medication, maintenance materials and feed ingredients. This might include an evaluation and disinfection procedure as well as quarantine time before bringing supplies near animals.
Good internal biosecurity helps keep diseases from moving around a farm. Internal biosecurity includes practices such as separating new piglets from older animals that might not be clinically ill but could be shedding some amount of virus. Setting up boot wash stations within the farm is important. Consider required glove changes as well as protocols requiring employees to move from younger to older pigs.
