ABSTRACT
The aim of this study was to determine the herd prevalence of veal and dairy herds and to identify risk factors for VTEC O157 positive veal herds. The study was based on monitoring data from November 1996 through July 2005 of 1051 dairy herds and 930 veal herds. The herd level prevalence (95% CI) was 8.0% (6.4-9.6) for dairy herds and 12.6% (10.5-14.7) for veal herds. Within the population of veal herds, a prevalence of 39.8% (33.9-45.6) was found for pink veal herds (n = 269) and 1.5% (0.7-2.8) for white veal herds (n = 661). Multivariable logistic regression showed that the type of veal (pink vs. white; OR = 21.6; 95% CI 10.4-45.0), ventilation (mechanical vs. natural; OR = 0.4; 95% CI 0.2-0.8), time between arrival in the herd and sampling (3-5 months vs. 0-2 months OR = 2.33; 95% CI 1.1-5.1, > or = 6 months vs. 0-2 months OR = 4.11; CI 1.9-8.9), other feed than the 7 most common (yes vs. no; OR = 2.1; 95% CI 1.2-3.7) and at least one dog present in the stable (yes vs. no; OR = 2.6; 95% CI 1.5-4.6) were significantly (P < 0.05) associated with the presence of VTEC O157. The large difference in the VTEC O157 prevalences for pink veal and white veal production might have been caused by a very different management of these type of herds. However, this could not be studied with the data collected.
