Epidemiology of Bovine Salmonellosis

Abstract

Salmonellosis is a disease with great economic and public health impact. Depending upon which salmonella serotype is involved in the disease process, there are also other associated problems: high morbidity in affected herds, abortion sequels, the problems of carrier cattle and the reoccurrence of salmonellosis in herds. Moreover, survivors of outbreaks are often unthrifty and take longer to reach marketable weight or do not regain lost milk production. Along with the lost revenues from decreased milk production are the costs of therapy and replacement animals, and public health problems leading to restrictions on the sale of milk and / or meat products.
