Why veterinary uniform policies are becoming an infection control issue

A new Vet Times commentary is putting a familiar but inconsistently enforced issue back on the table: whether veterinary staff should ever be seen off-site in uniform. Jane Davidson’s argument is straightforward, that if infection control problems emerge in a practice, no one wants to be the clinician recognized for wearing work attire to the shops, the pub, or a human hospital. Her position is that uniforms belong on practice premises, as one visible part of a broader infection control culture. That stance aligns with established human healthcare dress policies and current veterinary biosecurity guidance. (paperzz.com)

The background here is that veterinary medicine has long lagged human healthcare in formalized infection prevention systems, even as caseload complexity, patient throughput, and antimicrobial resistance concerns have grown. A widely cited review in the Journal of Veterinary Internal Medicine noted that infection control in veterinary hospitals often lacks the organized attention seen in human medicine, despite regular concerns about pathogens such as MRSA and methicillin-resistant Staphylococcus pseudintermedius. Vet Times has made a similar point more bluntly, arguing that some practices still treat hygiene as little more than “cleaning,” with limited understanding among clinical teams of disinfectant choice, microbiological risk, or the science behind effective decontamination. Earlier AVMA reporting also highlighted on-site laundry and keeping work clothes at work as practical measures for strengthening infection control. (academic.oup.com)

Davidson’s position also has a policy analogue in the NHS. Welsh and UK NHS dress guidance has for years advised that, where changing facilities exist, staff should change out of uniform before leaving work and should not wear uniforms in public places such as shops, with limited exceptions for staff travelling as part of their duties. Other NHS trust policies use similar language, including explicit references to supermarkets, shops, and public houses. While those are human healthcare policies, they’re relevant because they reflect a mature infection control framework built around both contamination risk and public confidence. (paperzz.com)

Veterinary-specific guidance supports the same direction of travel. AAHA’s infection control, prevention, and biosecurity guidelines state that some PPE and professional garb used in clinical settings should not be worn outside the work environment. The group says lab coats and scrubs should be laundered at least daily, or when contaminated, and notes that linens and professional garb can serve as fomites that transport pathogens within the practice and into the community. AAHA further recommends onsite or specialized commercial laundering when possible, because moving soiled garments to homes or other facilities increases infection control risk. In one referral-hospital study summarized by RCVS Knowledge, about two-thirds of staff reported not regularly changing their work clothing before travelling home, showing how common the gap between policy and behavior can be.

The wider hygiene case for stricter attire rules is also stronger than a simple “don’t wear scrubs to the supermarket” message suggests. Vet Times has argued that rising throughput and routine preoperative antibiotic use can hide poor hygiene performance by suppressing, rather than solving, contamination problems. The same article warned that many staff who deal with disinfectant suppliers may not fully understand the technical differences between products, even though susceptibility varies widely between Gram-positive and Gram-negative bacteria, fungi at different growth stages, and enveloped versus non-enveloped viruses. It also highlighted biofilms as a major practical problem in veterinary settings, because surface-associated microbial communities can be far more resistant to antimicrobials than free-floating organisms and may contribute to recurrent infections, resistance spread, and hospital-associated complications during longer stays or intensive care. Airborne spread, including via dust particles, adds another route of transmission that basic “visible cleanliness” may miss. (vettimes.com)

Direct expert reaction to Davidson’s commentary was limited in public sources, but the broader professional message is consistent. AAHA’s implementation materials describe clothing and PPE as potential sources of transmission if handled poorly, and provide example protocols in which scrubs remain on premises and are laundered by the practice. AVMA-endorsed standard precautions for zoonotic disease prevention also reinforce the need for structured infection control programs in veterinary settings. Taken together, the industry signal is less about fashion or optics alone, and more about reducing preventable pathogen movement while demonstrating professional standards to colleagues, clients, and the public.

Why it matters: For veterinary professionals, uniform policy sits at the intersection of infection prevention, workforce operations, and trust. A clinic that asks staff to change on-site needs lockers, changing space, and a workable laundry process, but those operational costs may be easier to justify as practices face greater scrutiny around hospital-associated infections, antimicrobial stewardship, and zoonotic risk. The policy can also protect staff by making expectations clearer: if uniforms are clinical equipment, not commuter clothing, then practices may need to provide enough sets, laundering support, or both. It also fits a broader lesson from veterinary hygiene reporting: infection control failures are rarely about one dramatic lapse, and more often about cumulative weak points in cleaning, disinfection, airflow, surface contamination, and staff habits that let pathogens persist. For pet parents, meanwhile, visible discipline around attire can signal that hygiene protocols are taken seriously long before they ever see the isolation ward. (aaha.org)

There’s also a reputational layer. Davidson’s framing suggests that what staff wear beyond the clinic can shape how a practice is judged if an infection control lapse later comes to light. That’s partly an optics issue, but it’s also a reminder that infection control is cumulative: hand hygiene, PPE use, laundry handling, traffic flow, disinfectant selection, biofilm control, air quality, and staff clothing all contribute to whether pathogens stay contained. In that sense, a no-uniforms-off-site rule may be one of the simplest policies for practices to explain, observe, and enforce. This is an inference based on the infection control guidance and the commentary’s emphasis on professional standards. (aaha.org)

What to watch: The next step is likely to be more formalization, with practices folding attire rules into written infection control plans, auditing compliance, and reassessing whether they have the facilities to support on-site changing and laundering rather than leaving uniform hygiene to individual staff habits. Expect some clinics to widen that review to the basics Vet Times says are often overlooked: whether staff understand the products they use, whether disinfectants match the organisms they are trying to control, and whether hidden reservoirs such as biofilms or airborne contamination are being addressed as seriously as visible dirt.
