Biosecurity and Health Checklists
The Avian Influenza Biosecurity Checklist for Texas Dairy Farms (PDF)
Avian influenza reached dairy cattle, and that changed how farms think about gates and boots. This is a build-your-own checklist, not a downloadable file, so confirm current guidance with the agencies named below.
What changed when avian influenza showed up in dairy cattle?
For years most dairy producers thought of avian influenza as a poultry problem. Detections in dairy herds changed that, and the response involved federal and state animal health agencies, veterinarians and processors. Specifics of what has been found and where are as reported by those agencies, so check the current picture with USDA APHIS and the Texas Animal Health Commission.
The practical lesson is that anything that moves between farms can carry disease: animals, milk, equipment, vehicles and people. Biosecurity is simply a plan for controlling those movements.
Which questions belong on a farm entry checklist?
Start at the gate. Who is allowed on the property, where do they park, and what do they walk through to reach the barns? A good plan is written down and short enough that a new employee can follow it on day one.
Post the plan where drivers and visitors see it before they enter. Keep a simple log of who came, when, and which areas they visited. If a veterinarian ever needs to trace contacts, a log beats memory every time.
Feed deliveries and rendering pickups are another gate. Ask suppliers to stop at a designated drop point outside the working area where possible, and agree in advance on who is responsible for cleaning shared equipment before and after it crosses your property.
- Single marked entry point for visitors
- Visitor and vehicle log
- Dedicated boots and coveralls for animal areas
- Wash station for vehicles that enter working areas
How should milk, equipment and animals be handled?
Think about the flow of everything that touches milk. Milking parlor surfaces, hauler access points and shared equipment all deserve a cleaning routine your vet agrees with. Ask your veterinarian which disinfectants are appropriate, because product choice and contact time matter.
New or returning animals are the other big door. Ask your herd veterinarian about isolation, testing before movement and what the state requires. The Texas A&M AgriLife Extension dairy team and the dairy herd health basics guide are helpful for building routines around this.
Calves deserve their own thought. Shared buckets, nipples and colostrum handling can move germs between animals, so ask your vet which feeding and cleaning routines make sense, and what the farm should do with milk from sick or treated cows.
What about workers, family and wild birds?
People carry disease on clothing and equipment, so training is part of the plan. Explain why the rules exist, in plain language and in the languages your crew speaks. Workers who feel unwell should know how to report it and who will talk with them. Public health guidance is available from the CDC, and the OSHA site covers protective equipment.
Wild birds and poultry on or near the farm deserve attention too. Keep feed covered, stop standing water where waterfowl gather, and ask whether backyard flocks nearby are a concern. In the Texas Panhandle, where large dairies and migratory routes overlap, this deserves a real conversation with your vet.
Who do you call if something looks wrong?
Write the numbers on the checklist itself: your herd veterinarian, the state animal health commission and your milk buyer. Reporting rules are set by the agencies and can change, so confirm what must be reported and how fast.
Early calls are rarely wasted. A sudden drop in milk, off-feed cows or thick, discolored milk are the sort of signs vets want to hear about promptly. Do not guess at causes or treatment on your own; let the vet lead.
How do you keep the plan alive?
Review the checklist twice a year and after any near miss. Walk the farm as a visitor would and note where a stranger could wander into the wrong area. Share what works with neighbors, since one farm's gap can become everyone's problem.
Farm.FM runs dairy stories that are a nice break after a long day of audits, and you can find a farm.FM piece on dairy biosecurity alongside the dairy section and farm news. Keep the humor outside the barn and the protocols inside it.
What does a one-page plan look like?
Put the plan on a single page with headings: entry, vehicles, people, animals, milk, wildlife and calls. Under each, list two or three rules in plain words and the name of the person responsible. A plan with owners gets followed; a plan with nobody's name on it gets filed.
Run a quick drill once a year. Pretend a hauler reports a sick herd on a neighboring farm and ask what your crew would do in the next hour. The gaps show up fast, and fixing them costs almost nothing compared with finding them in a real event. The farm safety checklist guide has useful ideas for drills and signage.
