Foot-and-Mouth Disease in Goats: Mouth Blisters, Lameness, and Reporting
- See your vet immediately if your goat has blisters, erosions, drooling, fever, or sudden lameness.
- Foot-and-mouth disease (FMD) is a highly contagious viral disease of cloven-hoofed animals, including goats.
- Goats may show milder signs than cattle, which can make outbreaks harder to spot early.
- FMD cannot be confirmed by appearance alone. Other diseases, including vesicular stomatitis and orf, can look similar.
- Suspected cases must be reported right away to animal health authorities through your vet or directly to State or Federal animal health officials.
- Typical initial veterinary visit and foreign animal disease workup on-farm may range from $150-$600 for the exam and farm call, but official regulatory testing and response steps may be directed by animal health authorities rather than handled like a routine private-practice case.
What Is Foot-and-Mouth Disease in Goats?
Foot-and-mouth disease, often called FMD, is a severe, fast-spreading viral disease that affects cloven-hoofed animals such as goats, sheep, cattle, pigs, and deer. Infected animals can develop fever, painful blisters or erosions in the mouth and on the feet, drooling, and lameness. The virus spreads very easily between susceptible animals, and animals may shed virus before obvious signs appear.
In goats, the disease can be harder to recognize than in cattle because signs may be milder or less dramatic. A goat may show only subtle mouth sores, reluctance to walk, or a drop in appetite. That matters because even mildly affected animals can still contribute to spread within a herd or to other livestock.
This is also a reportable foreign animal disease concern in the United States. As of March 14, 2026, the United States has not had an FMD case since 1929, so any suspicious blistering disease in goats needs urgent veterinary attention and official reporting. FMD is not the same as hand, foot, and mouth disease in people, and USDA says it is not a human health or food safety threat.
Symptoms of Foot-and-Mouth Disease in Goats
- Fever
- Blisters or raw erosions in the mouth
- Excessive drooling or stringy saliva
- Sudden lameness or reluctance to stand
- Reduced appetite
- Depression or isolation from the herd
- Drop in milk production
- Nasal discharge
- Abortions after high fever
- Sudden death in kids
When to worry: right away. Mouth blisters, drooling, and sudden lameness in a goat are not symptoms to watch at home. Goats can show subtle signs, and several serious diseases can look similar at first. Keep the affected goat isolated as much as possible, limit movement of animals, people, vehicles, boots, and equipment, and contact your vet immediately so they can guide safe next steps and reporting.
What Causes Foot-and-Mouth Disease in Goats?
FMD is caused by the foot-and-mouth disease virus, an Aphthovirus in the Picornaviridae family. There are 7 major virus types and many subtypes, so immunity to one type does not protect against all others. After exposure, the virus typically incubates for about 3 to 8 days in sheep and goats, although timing can vary.
The virus spreads through direct contact with infected animals, contaminated equipment and clothing, animal transport, shared handling areas, and in some situations by airborne spread. Virus is present in large amounts in blister fluid and oral secretions, and infected animals may spread it before visible lesions appear.
For goat herds, risk increases with animal movement, contact at markets or fairs, shared trailers, visitors who have been around other livestock, and contaminated boots, feed areas, or tools. Travel-related contamination also matters. USDA warns that animal disease agents can survive on shoes, clothing, and other items brought back from affected regions.
Because the United States is considered free of FMD, a suspicious case in a goat is treated as an animal health emergency, not a routine skin or mouth problem. Your vet will help decide whether signs fit a more common condition such as orf or foot rot, or whether official foreign animal disease reporting is needed immediately.
How Is Foot-and-Mouth Disease in Goats Diagnosed?
FMD cannot be diagnosed by appearance alone. Several diseases can cause mouth sores, drooling, and lameness in goats, including orf, bluetongue, vesicular stomatitis, foot rot, and chemical or thermal injury. That is why any suspicious blistering disease needs urgent veterinary evaluation.
Your vet will start with a careful history and exam, including recent animal movement, contact with other livestock, travel exposure, and whether more than one animal is affected. If FMD is suspected, your vet should stop routine movement, use strict biosecurity, and contact the appropriate State animal health official and USDA APHIS channels. APHIS states that diagnosed or suspected cases of nationally reportable animal diseases must be reported to the APHIS Area Veterinarian in Charge and the State animal health official.
Confirmation requires specialized laboratory testing, not an in-clinic visual diagnosis. Depending on lesion stage and official protocols, samples may include vesicular material, lesion swabs, epithelial tissue, blood, or other approved specimens collected under regulatory guidance. Blood testing can miss infection once viremia has passed, so sample choice and timing matter.
If your goat has suspicious signs, do not lance blisters, transport the animal to a sale barn, or move animals off the property unless animal health officials direct you to do so. Early reporting protects your herd and neighboring farms.
Treatment Options for Foot-and-Mouth Disease in Goats
Spectrum of Care means you have options. Here are treatment tiers at different price points.

Recommended Standard Treatment
- Urgent veterinary exam with full biosecurity precautions
- Regulatory notification and coordination with animal health authorities
- Supportive care plan for hydration, nutrition, nursing care, and pain management as directed by your vet
- Assessment of the rest of the herd for fever, oral lesions, and lameness

Cost estimates as of 2026-03. Actual costs vary by location, clinic, and individual case.
Questions to Ask Your Vet About Foot-and-Mouth Disease in Goats
Bring these questions to your vet appointment to get the most out of your visit.
- Do these mouth or foot lesions look suspicious for a reportable vesicular disease, or is another condition more likely?
- Should I isolate this goat from the rest of the herd right now, and how strict should that separation be?
- Do I need to stop all animal movement, visitors, and equipment sharing until we know more?
- Which signs in my other goats should I start checking for today, including fever, drooling, or subtle lameness?
- If FMD is on the list of concerns, who will contact the State animal health official or USDA APHIS?
- What samples are most useful at this stage, and should they be collected under official guidance?
- What supportive care is appropriate for this goat while we wait for results or instructions?
- What cleaning and disinfection steps should I use for boots, pens, feeders, trailers, and handling tools?
How to Prevent Foot-and-Mouth Disease in Goats
Prevention centers on biosecurity and rapid reporting. Limit unnecessary visitors, avoid sharing trailers and equipment without cleaning and disinfection, quarantine new or returning animals, and keep good records of purchases, shows, fairs, and off-farm movement. If anyone on the farm has recently traveled internationally or visited livestock facilities elsewhere, pay extra attention to footwear, clothing, and gear before they enter goat areas.
USDA advises travelers not to bring back prohibited animal products and to avoid carrying contamination on dirty shoes or clothing. That matters because FMD virus can move on contaminated items even when no sick goat is present on your property yet.
Watch your herd closely for fever, drooling, mouth sores, and lameness, especially after new animal introductions or contact with outside livestock. Because goats may show milder signs, a small change in gait or appetite deserves attention. Early recognition is one of the most practical ways to reduce spread.
If you suspect FMD, prevention becomes containment: isolate affected animals, stop movement on and off the property, and contact your vet immediately. Fast reporting is part of prevention because it helps protect neighboring herds, local agriculture, and the wider livestock community.
