OSHA Letter of Interpretation

Does OSHA have veterinary-specific safety guidelines?

No. Asked directly in 1994, OSHA's own medical office pointed to CDC and AVMA materials rather than to any veterinary standard of its own.

There is no OSHA rulebook for veterinary medicine. Practices are governed by general industry standards written for workplaces at large, supplemented by the General Duty Clause where no standard exists. A 1994 internal memorandum is the clearest official acknowledgment of that structure: asked what guidance existed for veterinarians, OSHA's Office of Occupational Medicine surveyed the field and pointed outward, to the CDC and the AVMA, rather than to anything of its own.

Background

The memorandum was issued on April 27, 1994 to Linda R. Anku, Regional Administrator for Region III, in response to an earlier inquiry regarding occupational hazards to veterinarians. It was authored by Joseph M. Tonning, MD, MPH, and Angela C. Presson, MD, MPH, of the Office of Occupational Medicine, and routed through Stephen Mallinger, Acting Director of the Directorate of Technical Support, and Melissa A. McDiarmid, MD, MPH, Director of the Office of Occupational Medicine.

Unlike the other letters in this section, this is not a response to a regulated party asking whether a rule applies. It is OSHA's medical staff reporting internally on what guidance exists.

What the survey found

The authors contacted the Centers for Disease Control and Prevention, the American Animal Hospital Association, and the American Veterinary Medical Association. On the zoonotic question, they reported:

According to Arnold Kaufman, DVM, at the CDC, brucellosis is the major concern among diseases that could potentially be transmitted from animals to veterinarians. Dr. Kaufman was unaware of any specific guidelines for veterinarians when handling animals, although he referred to the CDC/NIH publication Biosafety in Microbiological and Biomedical Laboratories, 3rd Edition.

The finding is worth stating plainly, because the memorandum does not: OSHA asked the federal authority on zoonotic disease whether guidelines existed for veterinary animal handling, and was told they did not.

Where OSHA directed attention instead

The memorandum's substantive content is a set of references to material produced by others:

Another excellent source of information regarding occupational hazards to veterinarians is the Journal of the American Veterinary Medical Association. This journal recently published a four-part series of articles by Philip J. Seibert, Jr., CVT, the first three of which are attached. These articles discuss various occupational hazards as well as OSHA regulations such as those governing anesthetic gases, hazardous chemicals, medical waste, and compressed gas cylinders.

It further notes that the February 1, 1994 issue (Vol. 204, pp. 356-358) "specifically addresses disposal of medical waste and animal handling guidelines, citing the OSHA bloodborne pathogens standard," and that the journal "is considered authoritative among veterinarians," with roughly 85 percent of United States veterinarians holding AVMA membership.

The standards OSHA associates with this memorandum reflect that list rather than any veterinary rule: air contaminants (1910.1000), hazard communication (1910.1200), bloodborne pathogens (1910.1030), and compressed gases (1910.101).

Assessment

The direct practical value of this memorandum today is limited. It is thirty years old, it imposes nothing, it references a JAVMA series and a CDC publication edition that have both since been superseded, and its bloodborne pathogens framing was refined by OSHA's 2002 interpretation, which narrowed the standard's application to animal blood considerably.

Its value is structural. It documents, from inside the agency, that veterinary medicine has no dedicated OSHA framework, and that the applicable requirements are assembled from general industry standards. That remains true.

What this means for your practice

  1. Do not look for a veterinary OSHA standard. There is not one. Compliance is assembled from general industry standards that happen to apply, principally hazard communication, bloodborne pathogens, air contaminants, and compressed gases.
  2. Where no standard exists, the General Duty Clause governs. Waste anesthetic gas and ergonomic exposure are both regulated this way, with no specific rule to point to.
  3. Brucellosis was CDC's stated principal zoonotic concern. The reference is dated, but the underlying point holds: zoonotic exposure is a real occupational risk that OSHA does not specifically regulate.
  4. Professional guidance fills the gap OSHA leaves. The agency itself directs practices to AVMA and CDC material. That is a reasonable approach, provided it is not mistaken for a compliance program.
  5. Treat this document as context, not as authority. For current obligations, the 1993 hazard communication letters and the 2002 bloodborne pathogens interpretation are the operative guidance.

This memorandum dates from 1994. Interpretation letters explain existing requirements and do not create new obligations, and OSHA revises its guidance as new information becomes available. The publications it cites have since been superseded. Consult the original for the historical record rather than for current requirements.
