Impact and control of infection Salmonella spp. in pig production

Abstract

Human salmonellosis originating from pork is an important zoonotic disease, and the objective of this study was to evaluate seroprevalence of Salmonella spp. in intensive and extensive farming of pigs. The study was conducted in pigs originating from a farm of 2,000 sows with a closed cycle of production and extensive farming of pigs from a more of individual farmers. In pigs from intensive farming seroprevalence was 42% (63/150), while the extensive farming of pigs founded seroprevalence of 74% (74/100). After the results obtained, were introduced corrective measures at pigs. At the pig farm was introduced to strictly respect the principle of 'all in-all out' with the basic cleansing and disinfection of facilities between two generations of pigs. The extensive farming at ten pig producers the proposed measure is limited access to people other than the person who directly performs with pigs, as well as preventing access to other animal species (dogs, cats, birds) and regular pest control. After corrective measures in this study, there was a reduction of seroprevalence of Salmonella spp. to 8% (12/150) in the case of intensive farming, and to 52% (52/100) in extensive farming. The intensive use of blood was taken from 150, and extensive of 100 finishing pigs before and after corrective measures. The results showed that the implemented corrective measures base for the control of Salmonella spp. infections of pigs, which is the primary requirement in the current production from the aspect of health care pig, at the same time and in the food safety and public health protection.
