A Cross-sectional and descriptive study was carried out in countryside of Puerto Boyacá town for identification of Cochliomyia hominivorax myiasis risk factors on cattle. Fourty four cattle farms were selected with a not-random sampling. Personal interviews were carried out to livestock farmers. Land use, livestock production system, and products for treatment of screwworm myiasis were investigated on February 6-15 of 2007. Stuff and instructions were supplied for taking larvae from animal wounds afterwards register survey application. Those materials were collect since last week on April of 2007 until first week on May of 2007. Frequency analysis, cross-tabs measures and non parametric tests were used. 49 screwworm myiasis cases (0.4%) out of 12,325 registered cattle were found, in 18 (41%) out of 44 selected cattle farms. The main cause of wounds recorded was injury by barbed wire with 16 cases (32.7%). Body sites more frequently infested were navel and scrotum with 9 cases (18.4%) each one. Association between age group in cattle and screwworm myiasis cases was founded (P=0.000; α=0.05). Association between cattle production system and screwworm myiasis cases was founded (P=0.044; α=0.05). Usual handling of non appropriate products for screwworm myiasis treatment like "creolina" (31 farms), gasoline (4 farms), used motor lubricant oil (2 farms), Baygon® (1 farm) and Vanodine® (1 farm) was registered. It may be concluded that selected cattle farms shared risk factors, depending on cattle production system. It demands epidemiological intervention to avoid damages to animals and consumers for using of inappropriate products for treatment of traumatic myiasis.
