Alpaca Biosecurity Basics: Preventing Disease at Home, During Visits, and at Events

Start with traffic control. Keep a written visitor policy, limit access to alpaca areas, and ask anyone entering pens to wear clean boots or disposable boot covers. If visitors have recently handled other livestock, especially cattle or small ruminants, it is wise to add extra caution because some infectious agents can move on clothing, footwear, and equipment.

Set up clean and dirty zones. Feed storage, hay tools, water buckets, halters, and manure tools should stay on your property and should not be shared with neighboring farms unless they are thoroughly cleaned and disinfected first. Remove manure regularly, avoid overcrowding, and keep water sources clean and protected from fecal contamination.

Have a plan for isolation before you need it. A separate pen or shelter for sick, newly purchased, or returning alpacas should be away from the main herd, ideally with no shared fence line. Care for healthy alpacas first, then isolated animals last, and use separate boots, gloves, and handling gear in that area.

Quarantine is one of the most useful biosecurity tools because many infections spread before obvious signs appear. The Alpaca Owners Association advises quarantining alpacas returning from shows for two to three weeks after they come home. During that time, monitor appetite, manure, temperature if your vet recommends it, nasal discharge, coughing, and overall attitude.

New arrivals deserve the same careful approach. Ask your vet which screening tests make sense for your herd and region before introducing a new alpaca. For show animals, the AOA handbook requires veterinary check-in, review of the Certificate of Veterinary Inspection, microchip verification, and BVDV-negative PCR documentation for participating alpacas, along with quarantine procedures for animals showing fresh diarrhea or respiratory illness.

Quarantine works best when it is strict, not partial. Use dedicated feed tubs, water buckets, halters, and manure tools. Wash hands or change gloves after contact. If possible, avoid nose-to-nose contact through fencing and keep runoff, bedding, and manure from the quarantine area away from the resident herd.

Visits can be low risk when they are organized well. Before your vet, shearer, breeding consultant, or other farm professional arrives, ask what infection-control steps they already use between farms. Many professionals routinely clean footwear, outerwear, and equipment, but it is still reasonable to discuss your herd’s needs in advance.

Schedule healthy-herd work before examining any sick alpacas on the property. If one alpaca has diarrhea, fever, or respiratory signs, let your vet know before the visit so they can plan the safest workflow. Keep handling equipment ready, reduce unnecessary movement between groups, and clean high-touch surfaces after the visit.

For breeding visits or shared males, ask your vet about pre-visit testing, transport hygiene, and whether direct contact with outside animals can be reduced. Even brief contact at fence lines, loading areas, or shared pens can create avoidable risk.

Shows and public events combine transport stress, unfamiliar animals, and shared spaces, so preparation matters. Reassess each alpaca’s health before travel, even if it already has movement paperwork. The AOA advises immediate quarantine at the event if an alpaca develops diarrhea or other signs of illness.

Bring your own supplies whenever possible: water buckets, feed tubs, halters, leads, muck tools, and cleaning supplies. Do not share these items between farms or exhibitors unless they have been cleaned and disinfected. Keep manure picked up promptly, wash hands after handling alpacas, and avoid allowing the public to touch multiple animals without hand hygiene.

Check interstate movement rules well ahead of travel. AVMA explains that Certificates of Veterinary Inspection support movement, disease surveillance, prevention, traceability, and control, and requirements can vary by destination. The AOA also notes that some states may require specific identification or additional testing, so your vet should review current rules before you leave.

Call your vet promptly if any alpaca in quarantine or the main herd develops diarrhea, coughing, nasal discharge, fever, weakness, poor appetite, sudden weight loss, or unusual behavior. Merck notes that camelid BVDV can be associated with ill thrift, lethargy, weight loss, nasal discharge, pneumonia, abortion, stillbirth, and weak premature neonates.

See your vet immediately if an alpaca has trouble breathing, cannot stand, shows neurologic signs, has severe diarrhea, or if multiple alpacas become sick around the same time. Fast isolation and early veterinary guidance can protect both the affected alpaca and the rest of the herd.

If you are unsure whether a sign is serious, it is still worth calling. Biosecurity works best when concerns are addressed early, before one sick alpaca becomes a herd problem.
