Screwworm Update.

There are now thee infested zones in Arizona.

We found out yesterday that the State Vet's Office is letting us do the inspections now for New World Screwworm (NWS) movement forms as well as other veterinarians, but the veterinarian needs to be USDA accredited.

To move livestock out of the infested zones and travel within the state of Arizona, you have to have this paperwork and the animal has to be treated with an approved product for that species. If you are traveling out of state, you will also need a Health Certificate.

For pets this paperwork is not required if you travel within the state of Arizona, only if you got to a different state, which you will need a health Certificate as well. And keep in mind that each state has its own requirements and we have to look up each state case by cause. If you are traveling to a different state, please go to this website to look up the requirements.

If you want to know if you live in an infested zone or not, please go to this website and put in your address. If it cannot find your address, just use your zip code.

If you are traveling to Arizona with your animals and stay in a red zone, Yes you will need this paperwork to leave the state of Arizona to go to another state. If you don't stay in a red zone, you still need a Health certificate to cross state lines.

Keep in mind that health certificates are now only good for 5 days and the NWS form is also only good for 5 days.

Here is some more information on New World Screwworm that gives a good explanation of what it is and how it is spread. We care about this because of its ability to kill animals relatively quickly and the impact it can have on pets, wildlife, livestock, and the economy.

This pamphlet is a little old but still very relevant.

So like Dr. Parker said, we are getting to the point to where we cannot answer everyones questions individually through face book, there is just too many of them coming in. So what we are going to do is look through the questions and look for reoccurring questions and themes and try to answer them that way through another post or video.

He has been using the Phovia on his horse and it is amazing how quickly it helps heal wounds.

We are seeing some confusion about small animal movement. Dr. Parker Called the State Vets office again and confirmed that as of right now, there is no restriction of movement of small animals within the state of Arizona. The state vets office is recommending before you travel with your pets outside of the read zone, you have your animals seen by your veterinarian and have them on prevention.

For small animals, we currently carry Credelio Quattro and multiple sizes of regular Credelio in stock as well for dogs. We have some Credelio for cats but not much left.

There are other options as well and we have an online pharmacy, so what we don't have in stock, we can have the online pharmacy ship to your house.

Just a friendly reminder, if we haven't seen your animal, we cannot prescribe for it, we have to see them first.

Call (520) 632-3843 to make an appointment.

Screwworm Update

11/03/2026

Dr. Parker was able to speak with the state veterinarians office and got the full update on the quarantine.

If you live within the Red zone
-No restriction on movement of small animals (dogs, cats, etc) within the state of Arizona currently. If you leave the state you need a Health Certificate from a USDA Accredited Veterinarian (Which Dr. Parker is).
-Movement out of the red area for Large animals (Horses, cows, sheep, gots, pigs, chickens, Llamas, etc.) require an inspection from a veterinarian from the state vets office and then if you cross state lines, you also need a Health certificate from a USDA Accredited Veterinarian.

If you live within a yellow zone, there are no restriction on movement of any animals within the state of Arizona but a Health Certificate is required to cross state lines.

Please keep in mind, this may change as the situation unfolds.

Please get on the Arizona State Veterinarians website to check if you live in a Red zone or not.

We have had people asking if we know where the dog is located in Cochise county and we do not. We are not the attending veterinary clinic and if we were, due to privacy laws wouldn't be able to give that information out.

If you see a wound on any of your animals with maggots in it, it needs to be checked right away and samples taken.

On October 28, 2026, the Arizona Department of Agriculture (AZDA) in cooperation with the United States Department of Agriculture (USDA) announced Arizona's index (first) case of New World screwworm (NWS). The confirmed case was found in a canine in Cochise County when a local veterinarian examined the animal on the evening of October 26 and identified a wound on the canine's back heavily infested with maggots consistent with NWS characteristics. Scientific testing, in coordination with federal partners, verified the species.

"We have been preparing for this possibility for a long while and are acting swiftly," said State Veterinarian Dr. Ryan Wolker. "Because of the extensive outreach, coordination, and surveillance already in place, Arizona producers, veterinarians, and pet owners know what to look for and how to report suspected cases. That preparation is allowing us to move quickly to protect animal health in the state."
