NEW WORLD SCREWWORM!!!! New World Screwworm (NSW) has been confirmed in Arizona and some surrounding states. For all of our clients traveling to Arizona with your horses this winter here are latest requirements to get back into CA with your horses. Please note these can change at any time so plan ahead and check with a veterinarian BEFORE you need to travel home!
Good afternoon California Veterinarians,
As New World Screwworm (NWS) continues to expand in the United States, California and many other states have implemented additional entry requirements. As such, there are also restrictions on California horses going to states with infested zones and returning. For California origin horses who are going to an event in a state that has a confirmed NWS infestation (but outside of an established infested zone), and then returning to California within the specified timeframes, the requirements are below:
If the horse is going to an event in an infested state and returning to California within 72 hours of inspection:
A Certificate of Veterinary Inspection (CVI) from an accredited veterinarian.
A valid Equine Infectious Anemia (EIA) test within the past twelve months.
No movement permit number is required.
The owner must inspect the horse upon arrival (within 24 hours) back in California to ensure no clinical signs compatible with an NWS infestation.
If the horse is going to an event in an infested state and returning to California within 3-7 days of inspection:
A Certificate of Veterinary Inspection (CVI) from an accredited veterinarian.
A valid Equine Infectious Anemia (EIA) test within the past twelve months.
The owner must self-inspect their horses in the infested state to ensure no clinical signs compatible with an NWS infestation.
The owner must call CDFA while in the infested state to obtain a movement permit. They will need a copy of their Certificate of Veterinary Inspection (CVI) with them in order to obtain the permit number.
Owner must give a verbal statement when obtaining the permit that the horse did not enter an infested zone and is not showing clinical signs compatible with an NWS infestation.
The owner must inspect the horse upon arrival (within 24 hours) back in California to ensure no clinical signs compatible with an NWS infestation and report any compatible clinical signs to CDFA immediately.
If the horse is going to an event in an infested state and returning to California after more than 7 days from inspection:
The CVI from the California veterinarian is no longer valid. The owner will have to obtain a new CVI in the infested state from a local veterinarian.
Paper CVIs are allowed for California origin horses. However, if a CVI is obtained in an infested state , the CVI must be electronic. Also at this time, the Extended Equine CVI (EECVIs) from Global VetLink are not allowed for horses traveling from an infested state. Please note, the above requirements are only for horses going to an event in an NWS free or surveillance zone. If an animal travels through or stays in an infested zone, there are additional entry requirements, which you can find on our website (see below). A map of infested zones can be found at Arizona Department of Agriculture website, the New Mexico Department of Agriculture website and at the Texas Animal Health Commission website.
Our requirements can currently be viewed on CDFA’s website or on InterstateLivestock.com. If you have any questions, please don’t hesitate to contact us at either of the permitting emails above. Thank you for your assistance in managing the spread of NWS.
