Can anyone confirm or deny this about Frost Mallards? This was sent to me by a friend in the Carolinas. Could this be the beginning of the end??? Fire away fellas! Anyone heard anything about this? Picked up from the refuge Well it has happened. I knew this was coming Mallards from at least 2 of the 3 facilities comprising the Frost Waterfowl Trust in South Carolina have tested positive for H2, H5, and H7 subtypes of avian influenza. These were serological positives with additional PCR and virus isolation tests under way. The NCDA is most concerned about the H5 and H7 subtypes relative to the commercial poultry industry in NC. As you know, the Frost Hatchery is the source for mallards proposed for importation by the North Carolina Waterfowl Association. Under current agency policy, importations from the Frost Hatchery flock will not be allowed by anyone until this disease issue is resolved. Therefore, until further notice, do not issue any importation permits for waterfowl from the Frost Hatchery.
