💥ATTENTION livestock owners!💥

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has provided an important update on New World Screwworm which has been detected in a bovine in Zavala County, Texas. Read the full press release here: https://www.aphis.usda.gov/news/agency-announcements/usda-confirms-presence-new-world-screwworm-united-states

General information about New World Screwworm (NWS) can be found in the text below and in the attached infographic.

The adult screwworm fly is about the size of a common housefly (or slightly larger), with orange eyes, a metallic blue or green body, and three dark stripes along its back. It gets its name from the behavior of its larvae (maggots) as they burrow (screw) into the wound, feeding as they go. The maggots (larvae) cause extensive damage by tearing at the hosts’ tissue with sharp mouth hooks. The wound can quickly become enlarged and deeper as more maggots hatch and feed on living tissue.

Because they feed on live flesh, NWS maggots may burrow deep into wounds or openings, while other species of maggots may appear around the outer surface of the wound. In addition, even the smallest wounds have the potential to attract flies, so it is imperative that you keep a close eye on your animals for any signs of wounds.

Lastly, NWS infestations are a reportable disease! Immediately report any suspicious wounds, maggots, or infestations to a local accredited veterinarian, your State Animal Health Official, or a USDA veterinarian.

Nobody wants to be in an emergency situation with their horse but when it does, it’s good to be prepared! 🐴🚑🚨‼️

Most equine owners know that a negative Coggins test is a document required to be able to transport their animal across state lines, enter them in a competitive event, or board at someone's barn. But what does the phrase "negative Coggins test" actually mean?

A "Coggins" is a blood test that can only be performed by USDA-approved laboratories and checks for Equine Infectious Anemia (EIA) antibodies in the blood. Equine Infectious Anemia (EIA) is a potentially fatal blood-borne infectious viral disease that produces a persistent infection among equids nearly worldwide. Transmission through blood transfusions or contaminated needles/syringes, surgical instruments or dental equipment is most common. The virus can also be transmitted through vectors via fly bite.

The clinical signs of disease can vary dramatically from an acute infection to an inapparent form, but what is important to know is that it produces a persistent infection. Once an animal tests positive for EIA it becomes a lifelong source of disease transmission, so the owner can only choose between quarantine for life or humane euthanasia to ensure that large outbreaks of the disease don’t occur. There is no vaccine or treatment for EIA.

Take-home message: While a Coggins test is a necessary travel document, don’t forget that it's also first and foremost a way to identify and remove EIA carriers to keep the disease under control.

As the temperatures rise and we head towards summer this is good information! ☀️🐴☀️

As the temperatures rise and the sun stays out longer, make sure your equine friends are adequately protected from harmful UV rays. ☀️

Hot summer weather puts horses at risk not only for dehydration and heat stress but also the skin damage and discomfort that accompany a sunburn— just like humans.

A lot of equestrians love some chrome on a horse, but it's important to remember that those beautiful white markings and the non-pigmented pink skin underneath are more likely to suffer from sunburn, especially in areas where the skin is more sensitive — like around the eyes and the nostrils.

In addition to the pain and discomfort, horses that are prone to recurrent sunburn may also face other long-term consequences, like the increased likelihood of developing squamous cell carcinoma (a common cancer).

If your horse is susceptible to sunburn, contact your veterinarian for more information about sun damage and recommendations to keep your equine protected this summer.

HOW AND WHY DO HORSES GET ULCERS?

Equine gastric ulcers can affect any horse of any age. Up to 90% of racehorses and 60% of show horses, as well as non-performance horses and even foals are affected by equine gastric ulcers. Gastric ulcers result from the erosion of the stomach lining due to a prolonged exposure to the normal acid present in the stomach.

Unlike ulcers in humans, bacteria do not appear to cause equine gastric ulcers. Instead, this condition is often a man-made disease. Stall confinement alone can lead to the development of ulcers. A horse’s feeding schedule and high-grain diets can also contribute to the development of ulcers.

Stress, both environmental and physical, can increase the likelihood of ulcers, as can hauling, training, and mixing groups of horses. Strenuous exercise can decrease the emptying of the stomach as well as the blood flow, thus further contributing to the problem.

The treatment and prevention of gastric ulcers is directed at removing these predisposing factors, therefore decreasing acid production within the horse’s stomach. Prevention of ulcers is the key in helping your horse, as neutralizing the production of stomach acid is nature’s best antacid.

Please note that the only way to definitively diagnose ulcers is through a gastroscopy. An equine veterinarian should always be consulted in any case of suspected gastric ulcers to determine the best course of action and treatment for the individual horse.

This is a common issue we see in our practice. Good information for all of our horse owners!

WHAT IS CELLULITIS? 🔎

Cellulitis is a common condition in horses where there is infection/inflammation in the tissues of the limb, most often the distal limb.

WHAT MIGHT YOU NOTICE?
Owners often first notice a leg that suddenly looks and feels “not right.” While the exact signs can vary case to case, rapid-onset limb swelling is a classic sign. Fever is also a sign to watch for with cellulitis. If your horse's temperature is elevated, contact your vet.

DIAGNOSIS:
Because a swollen, painful leg can have different causes, your veterinarian may use a combination of:
• Physical exam and patient history
• Imaging, including ultrasound, to help assess what’s happening in the tissues and whether there are complicating factors.

HOW IS IT TREATED?
There is limited scientific evidence that definitively tells us the single “best” treatment plan for every horse, and more research is needed (especially to support responsible antibiotic use). Your vet may tailor the plan to your horse’s severity, comfort, and response to therapy.

QUICK ACTION MATTERS:
• Cellulitis can be more than “just swelling.” It can become serious, and in rare severe scenarios, cellulitis/lymphangitis has been reported to progress to distal limb ischemia (loss of blood supply) with catastrophic tissue damage.
• Cellulitis can also lead to a condition called lymphangitis where the lymphatic system is affected, so resolution becomes more difficult. Multiple episodes of cellulitis/lymphangitis in the same leg can cause scarring, which makes recurrence more likely and recovery more difficult.

⚠️Cellulitis needs individualized diagnosis and treatment:
• Call your veterinarian promptly if your horse develops sudden, significant lower-leg swelling, heat, pain, or lameness.
• Don’t self-treat with leftover antibiotics. The evidence base is limited, and appropriate antibiotic choices/duration matter for both patient outcomes and antimicrobial stewardship.
