USDA has biosecurity funds available to repay for truck washes and disinfectant purchases.
Funds can only be applied for if the premise meets the case definition of Confirmed Positive - positive test and pigs clinical (on or after June 5, 2014). In addition to meeting the case definition there must also be an individual herd management plan submitted for the verified premise applying for funds.
Any questions or concerns regarding reimbursement should be directed to USDA VS office. Contact USDA at firstname.lastname@example.org or 317-347-3100.
Negative Premises/Herd Declaration
Producers and veterinarians will work together to determine a premises is free of SECD/PEDv through monitoring clinical signs and negative testing.
Instructions for negative premises/herd declaration
Follow the instructions and sampling protocols.
Note: Accessions used for determining negative status must have a premises number on the laboratory accession. Lab accessions without a premises number do not qualify for determining negative status.
Next, the veterinarian or herd representative needs to complete and submit the Declaration of Negative Premise form.
Please note, different criteria is set for all-in/all-out facilities and continuous/breeding herds.
For continuous/breeding herds, multiple sampling protocols are available (choose the one that works best with your herd).
