Conclusion and RecommendationThere are clinical and sub-clinical Salmonellae infections in piglets and weaners in Gulu and Soroti districts.

Intensive management should be promoted to reduce the risk of NTS.

Non-typhoidal salmonellosis (NTS) is one of the most common food-borne zoonoses and is common among children, elderly and/or immuno-compromised persons. In piglets and growing pigs, NTS infections cause enterocolitis, septicemia and death. One of the ways to control NTS is to prevent Salmonellae infections in pigs and therefore, prevent contamination of pork and pork products. Risk factors for NTS in smallholder households, where most of the pigs are produced in Uganda, were investigated.

Free ranging piglets from Gulu (upper image) not protected against NTS. Black colonies of Salmonella (lower image)

Materials and MethodsA study was carried out in 2011 and 2012 in Gulu, and Soroti districts, in Uganda. Fecal samples collected from piglets and weaners in 93 households for bacteriological analysis. Information on potential risk factors collected using questionnaires. Postmortem investigations on some of the diarrheic piglets were performed.

Diarrhea due to clinical salmonellosis was observed and confirmed.

12% of the piglets and weaners had Salmonella.

39% of the households had at least one Salmonella-positive pig.

Intensive management was protective against Salmonella when compared with tethering and roaming (p= 0.016; OR = 0.112) or semi-intensive management (p= 0.048; OR = 0.115).
