Every shift, veterinary nurses and technicians do something that rarely appears in a job description: they expose themselves to chemical disinfectants. Again and again, across every reprocessing cycle, every tray wash, every cage clean.
Nobody raises it at team meetings. It doesn’t feature in most clinic risk assessments. And yet the evidence has been building for years.
This is the occupational health conversation the veterinary profession hasn’t had loudly enough.
What the Research Actually Says
NIOSH and the Merck Veterinary Manual have both documented chemical disinfectants as a recognised occupational hazard in veterinary settings. The risks are not theoretical — they are cumulative and well-evidenced:
- Skin irritation and dermatitis from repeated contact with quaternary ammonium compounds, glutaraldehyde, and chlorine-based products
- Respiratory symptoms, including occupational asthma, linked to aerosolised disinfectants in poorly ventilated clinic spaces
- Ocular exposure from splashing during tray washing and cage cleaning
- Long-term sensitisation, where repeated low-level exposure gradually lowers the threshold for allergic reactions

The Reprocessing Cycle Nobody Counts
In a busy small animal clinic handling 10 to 15 recovery or isolation cases per shift, each reprocessing cycle involves:
- Applying a disinfectant to the tray surface
- Waiting for the required contact time — often 5 to 10 minutes per CDC guidelines
- Rinsing, drying, and restacking
- Repeating after every single patient
The CDC Guideline for Disinfection and Sterilization in Healthcare Facilities is explicit: reusable equipment requires meticulous cleaning every time, with the correct product, correct dilution, and correct contact time. There are no shortcuts that preserve safety.
What the guidelines don’t calculate is the cumulative exposure for the person doing that work, shift after shift, month after month.

The Staffing Context Makes It Worse
AVMA research and reports consistently document a profession under sustained pressure: rising caseloads, staffing shortages, and high burnout rates — particularly among veterinary nurses and technicians. When teams are stretched, two things happen simultaneously: the reprocessing workload doesn’t decrease, and the margin for following full protocol narrows. Shortcuts — conscious or not — become more likely.
This isn’t a criticism of veterinary teams. It’s a systems problem. The design of the workflow creates the exposure. The question is whether there are smarter ways to design around it.

Upstream Thinking vs. Downstream Management
Most occupational health responses in veterinary clinics are downstream: better PPE, improved ventilation, mandatory training, and incident reporting. All valuable. All necessary.
But there is also an upstream question worth asking: what if certain high-risk areas didn’t require reprocessing in the first place?
In isolation wards, post-operative recovery, and high-turnover short-stay cases, the selective use of single-use, biodegradable treatment equipment removes the reprocessing cycle entirely from those settings. No chemical contact. No aerosolisation. No cumulative exposure for the team member doing the work.
This isn’t about replacing all reusable equipment. Steel trays remain the right solution for long-term housing and many clinical contexts. It’s about applying the appropriate tool to the appropriate setting — and recognising that in some areas, the reprocessing cycle is a risk that can simply be designed out.
The Conversation Worth Having
Veterinary medicine asks a great deal of the people who work in it. Long hours, emotional weight, physical demands, and — quietly, daily — chemical exposure that compounds over a career. The least the profession can do is talk about it openly. And wherever possible, design workflows that reduce that burden.
