Salmonellosis is usually associated with foodborne transmission. To identify risk from animal contact, we compared exposures of case-patients infected bovine-associated Salmonella subtypes those control-patients non-bovine-associated subtypes. We used data collected in New York and Washington, USA, March 1, 2008, through 2010. Contact farm animals during the 5 days before illness onset was significantly being a case-patient (odds ratio 3.2, p = 0.0008), after consumption undercooked ground beef unpasteurized milk were controlled for. cattle specifically also 7.4, 0.0002), food More cases salmonellosis humans might result direct contact cattle, as opposed to ingestion foods bovine origin, than previously recognized. Efforts control should include focus on transmission routes other foodborne.
