Cancer in veterinarians.
ABSTRACT Veterinarians come into contact with several potentially carcinogenic exposures in the course of their occupation. These exposures include radiation, anaesthetic gases, pesticides (particularly insecticides), and zoonotic organisms. This review aims to summarise what is known about the carcinogenic risks in this profession.
The levels of exposure to potential carcinogens in the veterinary profession are examined and evidence is reviewed for carcinogenesis of these substances in humans at doses similar to those experienced by veterinarians. The few published studies of cancer in veterinarians are also summarised.
Veterinarians have considerable potential for exposure to several known and potential carcinogens. Risks may be posed by work in clinics with poorly maintained x ray equipment, by use of insecticides, and from contact with carcinogenic zoonotic organisms. The few studies available suggest that veterinarians have increased mortality from lymphohaematopoietic cancers, melanoma, and possibly colon cancer.
The exposures examined in this review are not unique to the veterinary profession, and, as a consequence, information gathered on the carcinogenic risks of these exposures has implications for many other occupations such as veterinary nurses, animal handlers, and some farmers, as well as dentists, radiographers, and anaesthetists.

ABSTRACT: Several studies have reported association between animal contact and some cancer types, including lymphohaematopoietic, colon, pancreatic and neurological malignancies. We aimed to investigate the association between animal contact and risk of oesophageal squamous cell carcinoma (ESCC) in a case-control study in Kashmir, India, area with a relatively high incidence of ESCC. We recruited 703 histologically confirmed ESCC cases and 1664 controls individually matched to the cases for age, sex and district of residence. Information, including on animal contact, was obtained in face-to-face interviews using a structured questionnaire. Conditional logistic regression models were used to calculate ORs and 95% CIs. As compared with no contact with animals, daily close contact was associated with an increased risk of ESCC (OR 5.99; 95% CI 3.86 to 9.31) in models adjusted for several potential confounding factors, including multiple indicators of socioeconomic status. This association persisted in subgroups following stratification by a composite wealth score and occupation. Irregular contact with animals was not associated with ESCC risk. The association between duration of animal contact and ESCC risk was mixed; however, contact for more than 50 years was associated with an increased risk (OR 3.10; 95% CI 1.53 to 6.26). Frequency (p for trend, 0.001) and duration (p for trend, <0.001) of animal contact showed dose-response association with ESCC risk. Our results suggest an association between long-term and daily close contact with animals and ESCC. This association needs to be investigated in further studies.Occupational and environmental medicine 01/2014; DOI:10.1136/oemed-2013-101802 · 3.23 Impact Factor
Conference Paper: An overview of microbial exposure during veterinary medicine study[Show abstract] [Hide abstract]
ABSTRACT: Background / Purpose: Exposure to endotoxin, both in residential and occupational environments, is a well-known occupational health risk associated with several respiratory diseases. Exposure to dust and endotoxin is poorly described for veterinarians, veterinary students and co-workers (caretakers) and the exposure levels of endotoxin are generally unknown for this line of work.The aim of this study was to investigate the airborne inhalable dust and endotoxin exposure among veterinary students, veterinarians, and co-workers (caretakers) in various veterinary settings. Main conclusion: This study indicated that substantial endotoxin exposure is likely to occur for veterinarians, veterinary students, and care-takers in modern horse, poultry, and ruminant animal clinics; not only in animal houses, but also in examination rooms during practical work.European Respiratory Society Annual Congress 2010; 11/2010
