Why uniform policy is becoming an infection control issue

Uniform policy is getting renewed attention as a practical infection control issue in veterinary practice. In Vet Times, Jane Davidson makes the case that staff should wear uniforms only on practice premises and change before travelling to shops, pubs, or hospitals, arguing that clothing choices can either support or undermine a clinic’s wider biosecurity culture.

The argument lands in a profession that has been talking about hygiene for years. A 2015 Vet Times piece warned that growing caseloads, busier treatment areas, and routine antibiotic use had masked weaknesses in day-to-day hygiene systems. More recently, formal veterinary infection prevention guidance has moved toward a more structured, multimodal approach that includes PPE, dedicated attire, hand hygiene, environmental cleaning, and staff behavior outside high-risk clinical areas.

That broader guidance gives Davidson’s position more weight than a simple opinion piece might suggest. The RCVS-hosted OAHN best-practice document for small animal clinics states that coats, scrubs, and other dedicated hospital attire should not be worn outside the work environment. AAHA’s infection control and biosecurity guidelines similarly warn that linens and professional garb can serve as fomites, moving pathogens around the practice and beyond it. A recent review in Animal Health Research Reviews also found support for visual differentiation of workwear and routine laundering of clinical clothing as ways to reduce cross-contamination between hospital and community settings.

There’s also precedent from both veterinary teaching hospitals and human healthcare. UC Davis’ 2025 small animal infectious disease control protocol says hospital scrubs must never be worn outside the veterinary medical teaching hospital, and that scrubs worn outside the operating room should be covered. In human medicine, NHS-linked policies often frame changing in and out of uniform at work as best practice, although some documents note the evidence that off-site uniform wear itself directly increases infection risk is limited. That makes this partly an evidence question, and partly a policy, professionalism, and public-confidence question. (vetmed.ucdavis.edu)

Expert commentary in the available guidance tends to converge on the same operational point: dedicated attire works best when it’s embedded in a full infection control system. The OAHN resource emphasizes hospital attire as a routine infection control tool, while AAHA ties clothing practices to laundering, PPE use, and environmental controls. In other words, changing out of scrubs before the supermarket won’t compensate for weak hand hygiene or poor disinfection, but it can close one avoidable pathway for contamination. That’s also consistent with Davidson’s framing of uniforms as one component of a multimodal approach rather than a standalone fix. (knowledge.rcvs.org.uk)

Why it matters: For veterinary teams, the takeaway is operational. If a practice doesn’t already have a written policy on where uniforms can be worn, how they’re laundered, what happens after contamination incidents, and what staff should do when commuting, this is a governance gap as much as a hygiene gap. Clearer expectations can reduce cross-site contamination risk for locums and multi-branch teams, support antimicrobial stewardship efforts, and give practices a defensible position if a healthcare-associated infection, zoonotic exposure, or reputational complaint triggers review.

It also matters because pet parents notice. Human healthcare has long wrestled with the tension between limited direct evidence and strong public assumptions about what “clean” looks like. Veterinary practices face the same reality: if staff are seen wearing visibly clinical attire in public settings, especially during or after an infection control incident, perception can quickly become part of the story. Even where the microbiological risk is difficult to quantify, the reputational risk is not. That last point is an inference drawn from the healthcare policy discussion and the emphasis on professionalism in the Vet Times commentary. (khh.org.uk)

What to watch: The next step is likely not new regulation, but more local policy tightening, including dedicated changing areas, clearer laundering rules, and stronger staff training on when workwear should begin and end. (knowledge.rcvs.org.uk)
