Service providers that move from farm to farm provide a legitimate risk of spreading disease if they do not follow adequate protocols for visiting sites. They should always contact the farm manager ahead of their visit and follow the farm’s entry protocols.
Service Provider Checklist – Manitoba Pork
Service providers should contact barn personnel ahead of an intended visit and follow the farm’s biosecurity protocols for entry. Visits should be postponed if you have signs of cold, flu or stomach issues. Service providers should follow this checklist when visiting a farm.
Disinfectants act to inactivate pathogens and can be extremely effective when applied to a visually clean surface. Different disinfectants have different effectiveness against different pathogens, depending on their type, concentration, and contact time. Only certain disinfectants are effective against coronaviruses, such as PEDv.
At temperatures below freezing, propylene glycol (PG) can added to disinfectants to delay them from freezing and allow adequate contact time to kill pathogens. As much as 40% PG (by volume) must be used in the disinfectant solution to allow adequate contact time below -20°C.
Feed delivery personnel should not enter the barn and should only access the area around the feed bins. Bagged feed should be limited and should be delivered to a separate farm building. Delivery personnel should wear clean clothes and disposable boot covers when delivering feed. Feed trucks should be fully washed and disinfected at least once weekly or immediately following any visits to high-risk sites.
Biosecure Deadstock Removal – National Pork Board (US):
Deadstock pick-up should occur away from the barns, preferably near a public access road. Deadstock haulers should not need to cross the same path as farm and delivery vehicles/workers.
