Animals have been implicated as an important source of injury for farm household members. On dairy farms, many injuries occur while milking. However, little is known about which environmental exposures may increase or decrease the risk for a milking injury. The primary aim of this nested case-control study (36 cases, 94 controls) was to identify which milking-related environmental exposures were associated with an increased or decreased risk of injury. Logistic regression was used to model the dependence of injury involving milking dairy cattle on environmental exposures of interest and confounders. Increased risks for milking injuries were associated with Grade B dairies (RR = 2.32); free stalls (RR = 3.02); restraining cattle (RR = 2.87); moving cattle to and from a milking facility (RR = 2.03); participation in two, three, or four job tasks associated with the milking activity (RR = 3.32, 6.09, and 9.27); and hilly terrain around the bam (RR = 3.66). A decreased risk was seen with the use of no kickers (RR = 0.30) and having dividers present between all stalls in the barn (RR = 0.35).
