“…The most often causes of injury were kicks, bites, and falls from farm animals (36%), falls from tractors and rollovers (24%), and falls from other farm machinery and attempts to unjam material from moving parts (28%) [Cogbill and Busch, 1985]. These causes have also been identified as major contributors to accidental-related injuries by several individuals [Cordes and Foster, 1988;Gunderson et al, 1990;Stallones, 1990;Cogbill et al, 1991;Brison and Pickett, 1992;Pratt et al, 1992;Zhou and Roseman, 1994;Nordstrom et al, 1995;Schulman et al, 1997;Stueland et al, 1997;Gerberich et al, 2001;Munshi et al, 2002;Browning et al, 2003]. In a recent review article, McCurdy and Carroll [2000] summarized the ranges of the percentage of injuries attributed to certain sources: machinery-18-35%, animals-12-33%, tractors-up to 40%, and falls-16-25%.…”
