Prevention of Laboratory Animal Allergy and Impact of COVID-19 on Prevention Programs in the United States

Abstract

Objective Laboratory animal allergy (LAA) is common and preventable. This study provides a 10-year update on LAA prevention programs in the United States and the effect of COVID-19 on prevention practices. Methods An electronic survey was e-mailed to designated institutional officials at laboratory animal facilities identified by the National Institutes of Health Office of Laboratory Animal Welfare. Results were compared with the prior survey. Results A total of 141 institutions employing 58,224 laboratory animal workers responded. Results were similar to the prior survey with wide variation in practices. Medical surveillance increased (58%–71%), but N95 respirator use decreased (17%–13%). As before, only 25% of institutions knew their LAA incidence and prevalence rates. COVID-19 had a small time-limited effect on personal protective equipment use. Conclusions Universal use of evidence-based practices and improved medical surveillance would provide greater worker protection from LAA.
