The Iowa Department of Agriculture and Land Stewardship announced the successful completion of all disease control measures in accordance with the program standards of the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA APHIS).
The second round of laboratory testing detected no additional cases of pseudorabies, confirming that the virus did not spread after it was first identified in late April.
The outbreak was initially detected on April 30, 2026, at a small commercial swine operation in Iowa. Following the detection, fewer than ten swine production facilities were placed under quarantine in accordance with established response protocols.
All quarantined farms subsequently completed a second round of testing, with all results returning negative. As a result, the quarantines have been officially lifted.
With the response measures now complete, pork producers within the control area are able to resume normal animal movements without additional restrictions.
The Iowa Department of Agriculture stated that the rapid response, effective biosecurity measures, and strict implementation of the USDA program standards enabled authorities to contain the outbreak and prevent the virus from spreading to other farms.
Maintaining official pseudorabies-free status is of significant importance to the U.S. pork industry, as it supports uninterrupted international trade and reinforces the confidence of trading partners in the country's veterinary health system.
