Abstract

We surveyed Wisconsin veterinarians to assess the frequency and severity of accidental self- and other human exposure to Mycobacterium paratuberculosis bacterin (Johne's bacterin). Of 199 veterinarians administering the bacterin to cattle, 22 reported one or more exposures, including 19 needle-stick exposures, 8 skin surface exposures, and 2 oral mucosa exposures. The mean incidence of needle sticks was 5.5/100 veterinarians/year of bacterin use or 1/1,000 doses administered. The mean total doses given in the needle-stick exposure group was 276 +/- 318 vs 80 +/- 268 in the group without needle-stick exposure, and the mean number of months administering the bacterin was 21.7 and 16.1, respectively; 63% of needle-stick exposures took place during the injection process. Five adverse reactions were reported, and each resulted from needle-stick exposure. The only systemic reaction followed an exposure to the original bacterin formulation of sonically ruptured M paratuberculosis in Freund incomplete adjuvant. The remaining reactions were to the current formulation of whole killed M paratuberculosis in mineral oil and ranged from a small nodule persisting for 4 to 6 months to painful inflammation of a finger persisting for 24 months. We anticipate an increase in incidence of these minimally debilitating injuries as the use and distribution of the bacterin expands. For hand wounds, we recommend conservative management. Surgical intervention should be considered if a granuloma persists and causes the patient functional difficulty.
