dc.description.abstractIntroduction: Epidemic porcine diarrhea is an infectious disease, which mainly attacks neonate piglets, with morbidity from 80 to 100% and mortality from 50 to 90%. The most rapid form of virus spread (PEDV) is the transport of swine. This disease got it to Colombia in 2014 affecting the national production without knowing the epidemiological behavior in the country. It has been previously reported worldwide that the fastest form of virus spread (PEDV) is the swine transport. Objective: Determine the prevalence of PEDV and factors associated with the transport of pigs to benefit plants. Methods: The research's design is a cross-sectional study, with a sample of 518 pig transport trucks in the 32 main slaughterhouses authorized in 2014 by the National Drug and Food Surveillance Institute (INVIMA) in the country, with proportional allocation according to the number of vehicle entrances to the plants. Sampling was carried out in the trucks at the entry and exit of the slaughterhouses, which were analyzed by RT-PCR and a survey applied to truck drivers. Results: The prevalence of PEDv at the ingress to plant was of 71,8% (CI 95% 70,8 - 72,8) vs. 70,5% (CI 95% 69,5 - 71,5) to the exit, p=0,375. Were evidenced as associated factors to the PEDv contamination of the trucks: the type of national slaughterhouse (OR 15,9, CI 95% 4,9 - 51,85) and national - exportation slaughterhouse (OR 9,0 CI 95%: 2,20 - 36,91), the zone of highest slaughter (OR 9,05 CI 95% 2,9 - 27,63) and the non-exclusive use of vehicle to swine transport (OR 3,75, CI 95%: 1,55 - 9,08) and the visit to plants of food concentrates (OR 13,5 CI 95%: 4,1 - 44,12). Were identified as factors that reduce the possibility of PEDv contamination the weekly or daily washing, use of disinfectants on the vehicle and it's the exclusive use to pig transport. Discussion: The results of the study, with a prevalence of 71.8% of PEDv in the trucks, show that the control measures in the pig transport process in Colombia present faults that facilitated the dissemination of PEDv.
