- Please be advised that the turn around time for review of health history surveys and clearance of personnel MAY take as long as two weeks.
- Surveys submitted less than two weeks prior to an IACUC Meeting, where a protocol is on the agenda, cannot be guaranteed to be acted upon in time for that meeting. This may result in the delay of protocol approval.
Occupational Health Program For Research Personnel With Animal Contact
Individuals who work with or near animals in a modern research setting are at risk for animal-related allergy, injury, and infectious disease. The risks are variable depending upon the species being used, the source of the animals, the quantity and quality of contact with or exposure to the animals and other factors.
The quality of today’s research animals greatly limits the chance of acquiring an infectious disease from the animals at GUMC. This is particularly true for anyone using purpose bred rodents or rabbits. The other animals used at GUMC pose slightly higher, but still very small, risks of infectious disease. The Division of Comparative Medicine (DCM) maintains a library with information on zoonotic diseases. Anyone desiring further information can contact the DCM Director.
Allergies are common in people working with or near laboratory animals. These include both inhalant and contact allergies. Nearly every species housed in the DCM has the potential to cause allergic reactions in susceptible individuals. In many cases the allergies develop after employment begins. Symptoms can vary but can include conjunctivitis, dermatitis, respiratory problems and anaphylaxis. Prevention of animal allergy depends on control measures in place within the work environment. A combination of methods to combat or limit allergen exposure, including administrative controls, training and education and the utilization of personal protective equipment has been implemented at Georgetown University.
Injuries are the most common occupational hazard for DCM staff members. Most of these are related to the equipment, lifting, repetitive motion, wet floors, etc. Investigators, their staff, and other individuals entering the animal facility should be watchful for wet floors and practice proper lifting techniques, as necessary. In addition, staff members are at risk of animal bites and scratches. Proper animal handling greatly reduces the potential for a bite or scratch.

- Occupational Health Program Health History Survey
All Animal Research Personnel working in a laboratory setting must attend training sessions in chemical and bio-hazard safety, emergency preparedness, basic laboratory safety, respiratory protection program training (fit testing and annual refresher), and accident investigation, blood borne pathogens and fire /electrical safety. Radiation safety training is required if animal research personnel will be working in a lab authorized to use radioactive materials. EH&S provides training (e.g. ergonomics) and additional retraining as necessary.
The DCM provides hands-on training, upon request of individual Animal Research Personnel or the Georgetown University Animal Care and Use Committee (IACUC), in humane methods of restraint and laboratory procedures with emphasis on injury prevention for both personnel and animals.
Personnel also are required to view specific courses in the ALL regarding potential occupational health risks in an animal care and use environment.
During NHP Safety Training class, a DCM clinical veterinarian provides training to employees working with nonhuman primates on the disease, history, clinical signs and zoonotic potential for B virus (Macacine herpesvirus 1); required PPE; location and proper use of Bite and Scratch Kits; and appropriate post-exposure medical and administrative follow-up. All employees working with nonhuman primates are required to receive this training.
Medical Clearance Procedures
1. Risk Assessment - Health History Survery
All Animal Research Personnel who are listed as participants on an approved IACUC protocol must complete a Health History Survey, receive health risk assessment, and obtain medical clearance, annually and prior to IACUC protocol renewal. All Animal Research Personnel, who will be listed as a participant and will work with animals on an IACUC protocol, must obtain medical clearance through the Occupational Health Program before the IACUC protocol can be approved or renewed. The Health History Survey is available here. Animal Research Personnel also receive the form during their required DCM orientation.
All completed surveys are sent directly to the Occupational Health Program Coordinator (“Coordinator”), who logs and forwards the form to the Medical Director. The Medical Director completes his risk assessment review - evaluating the following:
- Tetanus vaccination - Tdap if not received as an adult and Td booster every 10 years unless medically contraindicated. Personnel may decline vaccine by indicating this choice on the Td/Tdap Vaccine Declination form;
- TB screening - personnel working with nonhuman primates who do not have prior history of a positive TST (tuberculin skin test) receive a TST on enrollment. If the participant has received the Bacille Calmette-Guerin (BCG) vaccine, an interferon-gamma release assay (IGRA) blood test is ordered. If a participant is found to have a positive TST or IGRA, a TB Questionnaire is administered and chest x-ray is obtained unless participant can provide documentation of a normal chest x-ray within the last 12 months. Participant with prior history of positive TST or IGRA does not receive further testing. A TB Questionnaire is administered and a chest x-ray is obtained if the participant’s response to questionnaire suggests active pulmonary tuberculosis or the participant cannot provide documentation of a normal chest x-ray within the last two years following the discovery of the positive test;
- Hepatitis B - 3 doses of vaccine will be offered unless an individual has had prior doses of the vaccine. If prior doses of the vaccine were administered, the vaccine series will resume from the last dose received - the series does not need to be restarted. Employees may decline vaccine by indicating this choice on the Hep B Vaccine Declination Form;
- Measles (MMR) - Personnel working with nonhuman primates who have not had previous exposure to measles (e.g. had a natural case or been previously vaccinated and have laboratory evidence of immunity) will be offered the vaccine. Personnel may decline vaccine by indicating this choice on the Measles Vaccine Declination Form. If measles vaccine is declined or medically contraindicated, employee WILL NOT be cleared to work with nonhuman primates;
- Allergy assessment;
- Evaluation for respiratory protection, if indicated or requested;
- Pulmonary function studies, and/or chest x-ray, if indicated;
Appropriate specialty and subspecialty consultation where indicated
2. Medical Clearance
If additional tests, physical exams or health surveillance are needed, the Medical Director completes a “Medical Authorization and Order Form” and forwards it to the Coordinator. The Coordinator forwards an electronic copy of this form to the animal research personnel and assists in setting up appointments, as necessary, with the Clinical Research Unit (CRU). Upon notification of the need for additional tests, physical exam or health surveillance, all Animal Research Personnel will have thirty days to complete the clinical services. If clinical services are not administered within thirty days of receipt of notification, the IACUC will be notified and access to the DCM facility will be suspended.
After the individual has received his/her examination, testing and/or assessment, the Coordinator retrieves the Patient Encounter Form and completed Medical Authorization and Order Form from the CRU and forwards to the Medical Director for final review.
The Medical Director completes a “Medical Clearance to Work with Laboratory Animals” letter (Medical Clearance) and forwards to the Coordinator for distribution and logging into the program database. The Coordinator sends an electronic copy of the Medical Clearance letter to the individual and his/her PI, enters the medical clearance information into the program database and files the hard copy of the forms securely.
The Coordinator provides the IACUC the names of all animal research personnel who have obtained medical clearance. All medical history information will be maintained securely by the Coordinator.
The GUMC Occupational Health Program maintains strict confidentiality of patient information and records, in full compliance with HIPAA. Except for “Clearance to Work with Laboratory Animals” letters, no medical information is released to any agency without written consent from the examinee.[to top]
3. Annual Health Evaluation Assessment
Research personnel are required to complete and submit an Annual Health Evaluation form for review and approval by the Medical Director. The status of medical clearance of all personnel listed on an IACUC protocol is checked at the time of initial protocol submission, annual/triennial renewal and prior to amendment approval. Protocols will not receive approval unless all participants listed have full medical clearance to work with animals.
The DCM and research laboratories must make available personal protective equipment (e.g. lab coats, face masks, gloves, scrubs) in areas where animals may be present.
If research animals are transported outside the DCM, they must be moved in a filtered container (e.g. cages with microisolator filter tops for rodents). The outside of the container must be covered so that animals are not visible.
In the laboratory, animals should be maintained and handled in a local exhaust system such as a biological safety cabinet, fume hood or downdraft table. In areas where local exhaust systems are not feasible, laboratory ventilation is maintained in a negative pressure environment. Appropriate personal protective equipment is always required.
As applicable, research personnel are instructed to:
- Wear personal protective equipment in all locations where animals are housed or where exposure to animal allergies may occur;
- Wear disposable gloves when handling animals, animal tissues or animal fluids;
- Wear a surgical mask and face shield in all nonhuman primate housing areas;
- Keep hands away from mouth, nose and eyes;
- Refrain from eating, drinking, smoking, handling contact lenses, applying cosmetics or taking or applying medicine in areas where research animals are located;
- Wash hands thoroughly after handling animals, animal tissues or animal fluids; and
- Use and dispose of sharps properly and in accordance with GUMC regulated medical waste guidelines.
Allergies to animal dander and other allergens are common and may increase with long term exposure to animals. Occupational Health will assess a person’s needs and determine if wearing a respirator (e.g., N-95 mask, powered air purifying respirator or other type) or face mask and gloves will help alleviate allergy symptoms. Use of a respirator without clearance is prohibited. Occupational Health provides medical clearance and communicates as needed to EH&S who provides the required training and fit testing.
Bite and Scratch Procedures
Personnel who receive an animal bite that punctures the skin or a needle stick should:
- Identify the animal species and ID #;
- Clean the wound;
- Report to the GU Hospital Emergency Room or his/her private physician. An incident report will be completed by the injured party’s supervisor.
Personnel bitten by a nonhuman primate, scratched by a nonhuman primate or by nonhuman primate equipment, or who has any mucous membranes exposed to nonhuman primate secretions (e.g. urine, saliva, feces) are instructed to:
- Follow the instructions for wound care management found in the “Bite/Scratch/Splash Kit” located adjacent to the animal rooms;
- Immediately report incident to a DCM clinical veterinarian or DCM veterinary technician;
- Report to the GU Hospital Emergency Room or his/her own private physician for evaluation for Herpes B exposure. The potentially exposed person will take with him/her a copy of the B-Virus Exposure Management Protocol. An incident report will be completed by the person’s supervisor and other documentation will be completed by the treating physician.
Reporting Procedures for Animal-Related Illness or Injury
Research personnel who become ill or injured due to animal contact or animal allergen exposure should inform his/her primary care physician about his/her occupational exposure to animals. Where appropriate and indicated, specialty consultation will be obtained.
