Abstract

In the fall of 2001, a large commercial dairy calf and heifer raising operation in New York, USA, suffered an outbreak of acute neonatal diarrhoea. Prior to the outbreak, mortality before weaning was 2.5%, and during the outbreak preweaning mortality reached 10%. Multidrug-resistant Salmonella spp. serogroup C2 (serotype Newport) was recovered from clinically affected calves as well as from many environmental sites, including footbaths. This paper identifies some risk factors, such as low serum total protein, and reviews management protocols that were helpful, as well as those that were not (e.g., footbaths), for controlling transmission of Salmonella spp.
